Literary and historical notes of a young technician. How does the Julian calendar differ from the Gregorian calendar?

In Europe, starting in 1582, the reformed (Gregorian) calendar gradually spread. Gregorian calendar gives a much more accurate approximation of the tropical year. The Gregorian calendar was first introduced by Pope Gregory XIII in Catholic countries on October 4, 1582, replacing the previous one: the next day after Thursday, October 4, became Friday, October 15.
Gregorian calendar (" a new style") - a system of calculating time based on the cyclic revolution of the Earth around the Sun. The length of the year is taken to be 365.2425 days. The Gregorian calendar contains 97 by 400 years.

Difference between Julian and Gregorian calendars

At the time of the introduction of the Gregorian calendar, the difference between it and the Julian calendar was 10 days. However, this difference between the Julian and Gregorian calendars gradually increases over time due to differences in the rules for determining leap years. Therefore, when determining which date of the “new calendar” a particular date of the “old calendar” falls on, it is necessary to take into account the century in which the event took place. For example, if in the 14th century this difference was 8 days, then in the 20th century it was already 13 days.

This follows the distribution of leap years:

  • a year whose number is a multiple of 400 is a leap year;
  • other years, the number of which is a multiple of 100, are non-leap years;
  • other years, the number of which is a multiple of 4, are leap years.

Thus, 1600 and 2000 were leap years, but 1700, 1800 and 1900 were not leap years. Also, 2100 will not be a leap year. An error of one day compared to the year of the equinoxes in the Gregorian calendar will accumulate in approximately 10 thousand years (in the Julian calendar - approximately in 128 years).

Time of approval of the Gregorian calendar

The Gregorian calendar, adopted in most countries of the world, was not put into use immediately:
1582 - Italy, Spain, Portugal, Poland, France, Lorraine, Holland, Luxembourg;
1583 - Austria (part), Bavaria, Tyrol.
1584 - Austria (part), Switzerland, Silesia, Westphalia.
1587 - Hungary.
1610 - Prussia.
1700 - Protestant German states, Denmark.
1752 - Great Britain.
1753 - Sweden, Finland.
1873 - Japan.
1911 - China.
1916 - Bulgaria.
1918 - Soviet Russia.
1919 - Serbia, Rumania.
1927 - Türkiye.
1928 - Egypt.
1929 - Greece.

Gregorian calendar in Russia

As you know, until February 1918, Russia, like most Orthodox countries, lived according to the Julian calendar. The “new style” of chronology appeared in Russia in January 1918, when the Council of People's Commissars replaced the traditional Julian calendar in Gregorian. As stated in the Decree of the Council of People's Commissars, this decision was made “in order to establish in Russia the same calculation of time with almost all cultural peoples.” In accordance with the decree, the dates of all obligations were considered to have occurred 13 days later. Until July 1, 1918, a kind of transition period was established when it was allowed to use the old style calendar. But at the same time, the document clearly established the order of writing old and new dates: it was necessary to write “after the date of each day according to the new calendar, in brackets the number according to the calendar that was still in force.”

Events and documents are dated with a double date in cases where it is necessary to indicate the old and new styles. For example, for anniversaries, main events in all works of a biographical nature and dates of events and documents on the history of international relations associated with countries where the Gregorian calendar was introduced earlier than in Russia.

New style date (Gregorian calendar)

The Roman calendar was one of the least accurate. At first, it generally had 304 days and included only 10 months, starting from the first month of spring (Martius) and ending with the onset of winter (December - the “tenth” month); In winter there was simply no keeping track of time. King Numa Pompilius is credited with introducing two winter months (Januarius and Februarius). The additional month - Mercedonius - was inserted by the pontiffs at their own discretion, quite arbitrarily and in accordance with various momentary interests. In 46 BC. e. Julius Caesar carried out a calendar reform based on the developments of the Alexandrian astronomer Sosigenes, taking the Egyptian solar calendar as a basis.

In order to correct the accumulated errors, he, with his power as the great pontiff, inserted in the transitional year, in addition to Mercedonia, two additional months between November and December; and from January 1, 45, a Julian year of 365 days was established, with leap years every 4 years. In this case, an extra day was inserted between February 23 and 24, as before Mercedonia; and since, according to the Roman calculation system, the day of February 24 was called “the sixth (sextus) from the Kalends of March,” then the intercalary day was called “twice the sixth (bis sextus) from the Kalends of March” and the year accordingly annus bissextus - hence, through Greek language, our word is “leap year”. At the same time, the month of Quintilius was renamed in honor of Caesar (to Julius).

In the 4th-6th centuries, in most Christian countries, unified Easter tables were established, based on the Julian calendar; Thus, the Julian calendar spread to the entire Christian world. In these tables, March 21 was taken as the day of the vernal equinox.

However, as the error accumulated (1 day in 128 years), the discrepancy between the astronomical vernal equinox and the calendar one became increasingly obvious, and many in Catholic Europe believed that it could no longer be ignored. This was noted by the 13th-century Castilian king Alfonso X the Wise; in the next century, the Byzantine scientist Nikephoros Gregoras even proposed a calendar reform. In reality, such a reform was carried out by Pope Gregory XIII in 1582, based on the project of the mathematician and physician Luigi Lilio. in 1582: the next day after October 4th came October 15th. Secondly, a new, more exact rule about leap year.

Julian calendar was developed by a group of Alexandrian astronomers led by Sosigenes and introduced by Julius Caesar in 45 BC. uh..

The Julian calendar was based on the chronology culture of Ancient Egypt. In Ancient Rus', the calendar was known as the “Peacemaking Circle”, “Church Circle” and “Great Indiction”.


The year according to the Julian calendar begins on January 1, since it was on this day from 153 BC. e. the newly elected consuls took office. In the Julian calendar, a normal year consists of 365 days and is divided into 12 months. Once every 4 years, a leap year is declared, to which one day is added - February 29 (previously, a similar system was adopted in the zodiac calendar according to Dionysius). Thus, the Julian year has an average length of 365.25 days, which differs by 11 minutes from the tropical year.

The Julian calendar is usually called the old style.

The calendar was based on static monthly holidays. The first holiday with which the month began was the Kalends. The next holiday, falling on the 7th (in March, May, July and October) and on the 5th of other months, was Nones. The third holiday, falling on the 15th (in March, May, July and October) and the 13th of other months, was the Ides.

Replacement by the Gregorian calendar

In Catholic countries, the Julian calendar was replaced by the Gregorian calendar in 1582 by decree of Pope Gregory XIII: the next day after October 4 was October 15. Protestant countries abandoned the Julian calendar gradually, throughout the 17th-18th centuries (the last were Great Britain from 1752 and Sweden). In Russia, the Gregorian calendar has been used since 1918 (it is usually called the new style), in Orthodox Greece- since 1923

In the Julian calendar, a year was a leap year if it ended in 00.325 AD. The Council of Nicaea established this calendar for all Christian countries. 325 g day of the vernal equinox.

Gregorian calendar was introduced by Pope Gregory XIII on October 4, 1582 to replace the old Julian calendar: the next day after Thursday, October 4, became Friday, October 15 (there are no days from October 5 to October 14, 1582 in the Gregorian calendar).

In the Gregorian calendar, the length of the tropical year is taken to be 365.2425 days. The duration of a non-leap year is 365 days, a leap year is 366.

Story

The reason for the adoption of the new calendar was the shift in the day of the vernal equinox, by which the date of Easter was determined. Before Gregory XIII, Popes Paul III and Pius IV tried to implement the project, but they did not achieve success. The preparation of the reform, at the direction of Gregory XIII, was carried out by astronomers Christopher Clavius ​​and Luigi Lilio (aka Aloysius Lilius). The results of their work were recorded in a papal bull, named after the first line of the Latin. Inter gravissimas (“Among the most important”).

Firstly, new calendar Immediately at the time of acceptance, I shifted the current date by 10 days due to accumulated errors.

Secondly, a new, more precise rule about leap years began to apply.

A year is a leap year, that is, it contains 366 days if:

Its number is divisible by 4 and not divisible by 100 or

His number is divisible by 400.

Thus, over time, the Julian and Gregorian calendars diverge more and more: by 1 day per century, if the number of the previous century is not divisible by 4. The Gregorian calendar reflects the true state of affairs much more accurately than the Julian. It gives a much better approximation of the tropical year.

In 1583, Gregory XIII sent an embassy to Patriarch Jeremiah II of Constantinople with a proposal to switch to a new calendar. At the end of 1583, at a council in Constantinople, the proposal was rejected as not complying with the canonical rules for celebrating Easter.

In Russia, the Gregorian calendar was introduced in 1918 by a decree of the Council of People's Commissars, according to which in 1918 January 31 was followed by February 14.

Since 1923, most local Orthodox churches, with the exception of the Russian, Jerusalem, Georgian, Serbian and Athos, have adopted the New Julian calendar, similar to the Gregorian, which coincides with it until the year 2800. It was also formally introduced by Patriarch Tikhon for use in the Russian Orthodox Church on October 15, 1923. However, this innovation, although it was accepted by almost all Moscow parishes, generally caused disagreement in the Church, so already on November 8, 1923, Patriarch Tikhon ordered “the universal and mandatory introduction of the new style into church use to be temporarily postponed.” Thus, the new style was in effect in the Russian Orthodox Church for only 24 days.

In 1948, at the Moscow Conference of Orthodox Churches, it was decided that Easter, as well as all movable holidays, should be calculated according to the Alexandrian Paschal (Julian calendar), and non-movable ones according to the calendar according to which the Local Church lives. The Finnish Orthodox Church celebrates Easter according to the Gregorian calendar.

Julian calendar

Julian calendar- a calendar developed by a group of Alexandrian astronomers led by Sosigenes and introduced by Julius Caesar in 45 BC.

The Julian calendar reformed the outdated Roman calendar and was based on the chronology culture of Ancient Egypt. In Ancient Rus', the calendar was known as the “Peacemaking Circle”, “Church Circle” and “Great Indiction”.

The year according to the Julian calendar begins on January 1, since it was on this day from 153 BC. e. The consuls elected by the comitia took office. In the Julian calendar, a normal year consists of 365 days and is divided into 12 months. Once every 4 years, a leap year is declared, to which one day is added - February 29 (previously, a similar system was adopted in the zodiac calendar according to Dionysius). Thus, the Julian year has an average length of 365.25 days, which is 11 minutes longer than the tropical year.

365,24 = 365 + 0,25 = 365 + 1 / 4

The Julian calendar in Russia is usually called old style.

Monthly holidays in the Roman calendar

The calendar was based on static monthly holidays. The first holiday with which the month began was the Kalends. The next holiday, falling on the 7th (in March, May, July and October) and on the 5th of other months, was Nones. The third holiday, falling on the 15th (in March, May, July and October) and the 13th of other months, was the Ides.

Months

There is a mnemonic rule for remembering the number of days in a month: fold your hands into fists and, going from left to right from the bone of the little finger of the left hand to the index finger, alternately touching the bones and pits, list: “January, February, March...”. February will have to be remembered separately. After July (bone index finger left hand) you need to move to the bone of the index finger right hand and continue counting to the little finger, starting in August. On the underwires - 31, between - 30 (in the case of February - 28 or 29).

crowding out Gregorian calendar

The accuracy of the Julian calendar is low: every 128 years an extra day accumulates. Because of this, for example, Christmas, which initially almost coincided with the winter solstice, gradually shifted towards spring. The difference is most noticeable in spring and autumn near the equinoxes, when the rate of change in the length of the day and the position of the sun is maximum. In many temples, according to the creators' plan, on the day of the vernal equinox the sun should hit a certain place, for example, in St. Peter's Basilica in Rome this is a mosaic. Not only astronomers, but also the highest clergy led by the Pope could make sure that Easter no longer falls on old place. After a long discussion of this problem, in 1582 the Julian calendar in Catholic countries was replaced by a more accurate calendar by decree of Pope Gregory XIII. Moreover, the next day after October 4 was announced as October 15. Protestant countries abandoned the Julian calendar gradually, throughout the 17th-18th centuries; the last were Great Britain (1752) and Sweden.

In Russia, the Gregorian calendar was introduced by a decree of the Council of People's Commissars adopted on January 24, 1918; in Orthodox Greece - in 1923. The Gregorian calendar is often called new style.

Julian calendar in Orthodoxy

Currently, the Julian calendar is used only by some local Orthodox churches: Jerusalem, Russian, Serbian, Georgian, Ukrainian.

In addition, it is adhered to by some monasteries and parishes in other European countries, as well as in the USA, monasteries and other institutions of Athos (Patriarchate of Constantinople), Greek Old Calendarists (in schism) and other schismatic Old Calendarists who did not accept the transition to the New Julian calendar in Greece church and other churches in the 1920s; as well as a number of Monophysite churches, including in Ethiopia.

However, all Orthodox churches that have adopted the new calendar, except the Church of Finland, still calculate the day of Easter celebration and holidays, the dates of which depend on the date of Easter, according to the Alexandrian Paschal and the Julian calendar.

Difference between Julian and Gregorian calendars

The difference between the Julian and Gregorian calendars is constantly increasing due to different rules definitions of leap years: in the Julian calendar, all years divisible by 4 are leap years, while in the Gregorian calendar, a year is a leap year if it is a multiple of 400, or a multiple of 4 and not a multiple of 100. The leap occurs in the final year of the century (see Leap year ).

Difference between the Gregorian and Julian calendars (dates are given according to the Gregorian calendar; October 15, 1582 corresponds to October 5 according to the Julian calendar; other start dates of periods correspond to the Julian February 29, end dates - February 28).

Date difference Julian and Gregorian calendars:

Century Difference, days Period (Julian calendar) Period (Gregorian calendar)
XVI and XVII 10 29.02.1500-28.02.1700 10.03.1500-10.03.1700
XVIII 11 29.02.1700-28.02.1800 11.03.1700-11.03.1800
XIX 12 29.02.1800-28.02.1900 12.03.1800-12.03.1900
XX and XXI 13 29.02.1900-28.02.2100 13.03.1900-13.03.2100
XXII 14 29.02.2100-28.02.2200 14.03.2100-14.03.2200
XXIII 15 29.02.2200-28.02.2300 15.03.2200-15.03.2300

One should not confuse the translation (recalculation) of real historical dates (events in history) to another calendar style with the recalculation (for ease of use) to another style of the Julian church calendar, in which all days of celebration (memory of saints and others) are fixed as Julian - regardless of what Gregorian date a particular holiday or memorial day corresponded to. Due to the increasing change in the difference between the Julian and Gregorian calendars, Orthodox churches using the Julian calendar, starting in 2101, will celebrate Christmas not on January 7, as in the 20th-21st centuries, but on January 8 (translated to the new style), but, for example, from 9997, Christmas will be celebrated on March 8 (new style), although in their liturgical calendar this day will still be marked as December 25 (old style). In addition, it should be borne in mind that in a number of countries where the Julian calendar was in use before the beginning of the 20th century (for example, in Greece), dates historical events, which occurred before the transition to the new style, continue to be celebrated on the same dates (nominally) on which they occurred according to the Julian calendar (which, among other things, is reflected in the practice of the Greek section of Wikipedia).

As in other Christian countries, from the end of the 10th century in Rus' the Julian calendar was used, based on observations of visible movement Sun across the sky. It was introduced in Ancient Rome by Gaius Julius Caesar in 46 BC. e.

The calendar was developed by the Alexandrian astronomer Sosigenes based on the calendar of Ancient Egypt. When Rus' adopted Christianity in the 10th century, the Julian calendar came with it. However, the average length of a year in the Julian calendar is 365 days and 6 hours (that is, there are 365 days in a year, with an additional day added every fourth year). While the duration of the astronomical solar year is 365 days 5 hours 48 minutes and 46 seconds. That is, the Julian year was 11 minutes 14 seconds longer than the astronomical year and, therefore, lagged behind the real change of years.

By 1582, the difference between the Julian calendar and the real change of years was already 10 days.

This led to a reform of the calendar, which was carried out in 1582 by a special commission created by Pope Gregory XIII. The difference was eliminated when, after October 4, 1582, it was ordered to count not October 5, but immediately October 15. After the name of the pope, the new, reformed calendar began to be called the Gregorian calendar.

In this calendar, unlike the Julian calendar, the final year of the century, if it is not divisible by 400, is not a leap year. Thus, the Gregorian calendar has 3 fewer leap years in each four-hundredth anniversary than the Julian calendar. The Gregorian calendar retained the names of the months of the Julian calendar, an additional day in leap year- February 29 and the beginning of the year - January 1.

The transition of countries around the world to the Gregorian calendar was long. First, the reform took place in Catholic countries (Spain, Italian states, the Polish-Lithuanian Commonwealth, a little later in France, etc.), then in Protestant countries (in Prussia in 1610, in all German states by 1700, in Denmark in 1700, in Great Britain in 1752, in Sweden in 1753). And only in the 19th-20th centuries the Gregorian calendar was adopted in some Asian (in Japan in 1873, China in 1911, Turkey in 1925) and Orthodox (in Bulgaria in 1916, in Serbia in 1919, in Greece in 1924 year) states.

In the RSFSR, the transition to the Gregorian calendar was carried out according to the decree of the Council of People's Commissars of the RSFSR “On the introduction of the Western European calendar in the Russian Republic” dated February 6, 1918 (January 26, old style).

The calendar problem in Russia has been discussed several times. In 1899, a Commission on the issue of calendar reform in Russia worked under the Astronomical Society, which included Dmitry Mendeleev and historian Vasily Bolotov. The commission proposed modernizing the Julian calendar.

“Taking into account: 1) that in 1830 the petition of the Imperial Academy of Sciences for the introduction of the Gregorian calendar in Russia was rejected by Emperor Nicholas I and 2) that the Orthodox states and the entire Orthodox population of the East and West rejected the attempts of representatives of Catholicism to introduce the Gregorian calendar in Russia, the Commission unanimously decided to reject all proposals for the introduction of the Gregorian calendar in Russia and, without being embarrassed by the choice of reform, to settle on one that would combine the idea of ​​​​truth and possible accuracy, both scientific and historical, in relation to Christian chronology in Russia,” reads Resolution of the Commission on the reform of the calendar in Russia from 1900.

Such a long use of the Julian calendar in Russia was due to the position of the Orthodox Church, which had a negative attitude towards the Gregorian calendar.

After the church was separated from the state in the RSFSR, linking the civil calendar to the church calendar lost its relevance.

The difference in calendars created inconvenience in relations with Europe, which was the reason for the adoption of the decree “in order to establish in Russia the same calculation of time with almost all cultural nations.”

The question of reform was raised in the fall of 1917. One of the projects under consideration proposed a gradual transition from the Julian calendar to the Gregorian calendar, dropping a day each year. But, since the difference between the calendars by that time was 13 days, the transition would take 13 years. Therefore, Lenin supported the option of an immediate transition to a new style. The church refused to switch to the new style.

“The first day after January 31 of this year should be considered not February 1, but February 14, the second day should be considered the 15th, etc.,” read the first paragraph of the decree. The remaining points indicated how new deadlines for fulfilling any obligations should be calculated and on what dates citizens would be able to receive their salaries.

The change of dates has created confusion with the celebration of Christmas. Before the transition to the Gregorian calendar in Russia, Christmas was celebrated on December 25, but now it has moved to January 7. As a result of these changes, in 1918 there was no Christmas at all in Russia. The last Christmas was celebrated in 1917, which fell on December 25th. And the next time the Orthodox holiday was celebrated on January 7, 1919.





For all of us, the calendar is a familiar and even mundane thing. This ancient invention of man records days, dates, months, seasons, periodicity natural phenomena, which are based on the system of movement of celestial bodies: the Moon, the Sun, the stars. The Earth rushes through the solar orbit, leaving years and centuries behind.
In one day, the Earth makes one complete revolution around its own axis. It passes around the Sun once per year. The solar or astronomical year lasts three hundred sixty-five days, five hours, forty-eight minutes, forty-six seconds. Therefore, there is no integer number of days. Hence the difficulty in compiling accurate calendar for correct timing.
The ancient Romans and Greeks used a convenient and simple calendar. The rebirth of the Moon occurs at intervals of 30 days, or to be precise, at twenty-nine days, twelve hours and 44 minutes. That is why days and then months could be counted by changes in the Moon. In the beginning, this calendar had ten months, which were named after the Roman gods. From the third century BC to ancient world an analogue was used based on the four-year lunar-solar cycle, which gave an error in the value of the solar year of one day. Used in Egypt solar calendar, compiled on the basis of observations of the Sun and Sirius. The year according to it was three hundred sixty-five days. It consisted of twelve months of thirty days. After it expired, another five days were added. This was formulated as “in honor of the birth of the gods.”

History of the Julian Calendar Further changes occurred in the forty-sixth year BC. e. Emperor Ancient Rome Julius Caesar, based on the Egyptian model, introduced the Julian calendar. In it, the solar year was taken as the size of the year, which was slightly larger than the astronomical one and amounted to three hundred sixty-five days and six hours. The first of January marked the beginning of the year. According to the Julian calendar, Christmas began to be celebrated on January 7th. This is how the transition to a new calendar took place. In gratitude for the reform, the Senate of Rome renamed the month of Quintilis, when Caesar was born, to Julius (now July). A year later, the emperor was killed, and the Roman priests, either out of ignorance or deliberately, again began to confuse the calendar and began to declare every third year a leap year. As a result, from forty-four to nine BC. e. Instead of nine, twelve leap years were declared. Emperor Octivian Augustus saved the situation. By his order, there were no leap years for the next sixteen years, and the rhythm of the calendar was restored. In his honor, the month Sextilis was renamed Augustus (August).

For the Orthodox Church, the simultaneity of church holidays was very important. The date of Easter was discussed at the First Ecumenical Council, and this issue became one of the main ones. The rules for the exact calculation of this celebration established at this Council cannot be changed under pain of anathema. Gregorian Calendar Chapter Catholic Church Pope Gregory the Thirteenth approved and introduced a new calendar in 1582. It was called "Gregorian". It would seem that everyone was happy with the Julian calendar, according to which Europe lived for more than sixteen centuries. However, Gregory the Thirteenth considered that the reform was necessary to determine a more accurate date for the celebration of Easter, as well as to ensure that the day of the vernal equinox returned to the twenty-first of March.

In 1583, the Council of Eastern Patriarchs in Constantinople condemned the adoption of the Gregorian calendar as violating the liturgical cycle and calling into question the canons of the Ecumenical Councils. Indeed, in some years he breaks the basic rule of celebrating Easter. It happens that Catholic Bright Sunday falls earlier than Jewish Easter, and this is not allowed by the canons of the church. Calculation in Rus' On the territory of our country, starting from the tenth century, the New Year was celebrated on the first of March. Five centuries later, in 1492, in Russia the beginning of the year was moved, according to church traditions, on the first of September. This went on for more than two hundred years. On the nineteenth of December, seven thousand two hundred and eight, Tsar Peter the Great issued a decree that the Julian calendar in Russia, adopted from Byzantium along with baptism, was still in force. The start date of the year has changed. It was officially approved in the country. The New Year according to the Julian calendar was to be celebrated on the first of January “from the Nativity of Christ.”
After the revolution of February fourteenth, one thousand nine hundred and eighteen, new rules were introduced in our country. The Gregorian calendar excluded three leap years within each quadrant. This is what they began to adhere to. How are the Julian and Gregorian calendars different? The difference between is in the calculation of leap years. Over time it increases. If in the sixteenth century it was ten days, then in the seventeenth it increased to eleven, in the eighteenth century it was already equal to twelve days, thirteen in the twentieth and twenty-first centuries, and by the twenty-second century this figure will reach fourteen days.
The Orthodox Church of Russia uses the Julian calendar, following the decisions of the Ecumenical Councils, and Catholics use the Gregorian calendar. You can often hear the question of why the whole world celebrates Christmas on the twenty-fifth of December, and we celebrate the seventh of January. The answer is completely obvious. The Russian Orthodox Church celebrates Christmas according to the Julian calendar. This also applies to other major church holidays. Today the Julian calendar in Russia is called the “old style”. Currently, its scope of application is very limited. It is used by some Orthodox Churches - Serbian, Georgian, Jerusalem and Russian. In addition, the Julian calendar is used in some Orthodox monasteries in Europe and the USA.

Gregorian calendar in Russia
In our country, the issue of calendar reform has been raised more than once. In 1830 it was staged by the Russian Academy of Sciences. Prince K.A. Lieven, who served as Minister of Education at the time, considered this proposal untimely. Only after the revolution the issue was brought to a meeting of the Council of People's Commissars Russian Federation. Already on January 24, Russia adopted the Gregorian calendar. Peculiarities of the transition to the Gregorian calendar For Orthodox Christians, the introduction of a new style by the authorities caused certain difficulties. The New Year turned out to be shifted to the Nativity Fast, when any fun is not welcome. Moreover, January 1 is the day of remembrance of St. Boniface, the patron saint of everyone who wants to give up drunkenness, and our country celebrates this day with a glass in hand. Gregorian and Julian calendar: differences and similarities Both of them consist of three hundred sixty-five days in a normal year and three hundred sixty-six in a leap year, have 12 months, 4 of which are 30 days and 7 are 31 days, February is either 28 or 29 The only difference is the frequency of leap years. According to the Julian calendar, a leap year occurs every three years. In this case, it turns out that the calendar year is 11 minutes longer than the astronomical year. In other words, after 128 years there is an extra day. The Gregorian calendar also recognizes that the fourth year is a leap year. The exceptions are those years that are multiples of 100, as well as those that can be divided by 400. Based on this, extra days appear only after 3200 years. What awaits us in the future Unlike the Gregorian calendar, the Julian calendar is simpler for chronology, but it is ahead of the astronomical year. The basis of the first became the second. According to the Orthodox Church, the Gregorian calendar violates the order of many biblical events. Due to the fact that the Julian and Gregorian calendars increase the difference in dates over time, Orthodox churches that use the first of them will celebrate Christmas from 2101 not on January 7, as it happens now, but on January 8, but from nine thousand In the year nine hundred and one, the celebration will take place on March 8th. In the liturgical calendar, the date will still correspond to the twenty-fifth of December.

In countries where the Julian calendar was used by the beginning of the twentieth century, for example in Greece, the dates of all historical events that occurred after the fifteenth of October one thousand five hundred and eighty-two are nominally celebrated on the same dates on which they occurred. Consequences of calendar reforms Currently, the Gregorian calendar is quite accurate. According to many experts, it does not need changes, but the issue of its reform has been discussed for several decades. This is not about introducing a new calendar or any new methods for accounting for leap years. This is about rearranging the days of the year so that the beginning of each year falls on one day, such as Sunday. Today, calendar months range from 28 to 31 days, the length of a quarter ranges from ninety to ninety-two days, with the first half of the year being 3-4 days shorter than the second. This complicates the work of financial and planning authorities. What New Calendar Projects Are There Various designs have been proposed over the past one hundred and sixty years. In 1923, a calendar reform committee was created at the League of Nations. After the end of the Second World War, this issue was transferred to the Economic and Social Committee of the UN. Despite the fact that there are quite a lot of them, preference is given to two options - the 13-month calendar of the French philosopher Auguste Comte and the proposal of the French astronomer G. Armelin.
In the first option, the month always begins on Sunday and ends on Saturday. One day in the year has no name at all and is inserted at the end of the last thirteenth month. In a leap year, such a day appears in the sixth month. According to experts, this calendar has many significant shortcomings, so more attention is paid to the project of Gustave Armelin, according to which the year consists of twelve months and four quarters of ninety-one days. The first month of a quarter has thirty-one days, the next two have thirty. The first day of each year and quarter begins on Sunday and ends on Saturday. In a normal year, one additional day is added after the thirtieth of December, and in a leap year - after the 30th of June. This project was approved by France, India, Soviet Union, Yugoslavia and some other countries. For a long time The General Assembly delayed approval of the project, and in Lately this work at the UN ceased. Will Russia return to the “old style”? It is quite difficult for foreigners to explain what the concept “Old” means New Year"Why we celebrate Christmas later than Europeans. Today there are people who want to make the transition to the Julian calendar in Russia. Moreover, the initiative comes from well-deserved and respected people. In their opinion, 70% of Russian Orthodox Russians have the right to live according to the calendar used by the Russian Orthodox Church. http://vk.cc/3Wus9M
