Coptic calendar

Last updated

The Coptic calendar, also called the Alexandrian calendar, is a liturgical calendar used by the Coptic Orthodox Church and also used by the farming populace in Egypt. It was used for fiscal purposes in Egypt until the adoption of the Gregorian calendar on 11 September (6 Nesi) 1875. [1] This calendar is based on the ancient Egyptian calendar. To avoid the calendar creep of the latter (which contained only 365 days each year, year after year, so that the seasons shifted about one day every four years), a reform of the ancient Egyptian calendar was introduced at the time of Ptolemy III (Decree of Canopus, in 238 BC) which consisted of adding an extra day every fourth year. However, this reform was opposed by the Egyptian priests, and the reform was not adopted until 25 BC, when the Roman Emperor Augustus imposed the Decree upon Egypt as its official calendar (although initially, namely between 25 BC and AD 5, it was unsynchronized with the newly introduced Julian calendar which had erroneously been intercalating leap days every third year due to a misinterpretation of the leap year rule so as to apply inclusive counting). [2] To distinguish it from the Ancient Egyptian calendar, which remained in use by some astronomers until medieval times, this reformed calendar is known as the Coptic or Alexandrian calendar. Its years and months coincide with those of the Ethiopian calendar but have different numbers and names. [3]

Coptic year

The Coptic year is the extension of the ancient Egyptian civil year, retaining its subdivision into the three seasons, four months each. The three seasons are commemorated by special prayers in the Coptic Liturgy. This calendar is still in use all over Egypt by farmers to keep track of the various agricultural seasons. [4]

The Coptic calendar has 13 months, 12 of 30 days each and one at the end of the year of 5 days, or 6 days in leap years. The Coptic Leap Year follows the same rules as the Julian Calendar so that the extra month always has six days in the year before a Julian Leap Year. [5]

The year starts on the Feast of Neyrouz, the first day of the month of Thout, the first month of the Egyptian year. For 1901 to 2098 it coincides with the Gregorian Calendar's 11 September, or 12 September before a leap year, but for any year, it coincides with the Julian Calendar's 29 August, or 30 August before a leap year. Coptic years are counted from 284 AD, the year Diocletian became Roman Emperor, whose reign was marked by tortures and mass executions of Christians, especially in Egypt. [5] Hence, the Coptic year is identified by the abbreviation A.M. (for Anno Martyrum or "Year of the Martyrs"). The first day of the year I of the Coptic era was 29 August 284 in the Julian calendar. Note that A.M. abbreviation is also used for unrelated calendar eras (such as the Byzantine and Jewish calendar epochs) which start at the putative creation of the world; it then stands for Anno Mundi .

Easter is reckoned by the Julian Calendar in combination with the uncorrected repetition of the 19-year Metonic cycle. [6]

To obtain the Coptic year number, subtract from the Julian year number either 283 (before the Julian new year) or 284 (after it).

Date of Christmas

Coptic Christmas is observed on what the Julian Calendar labels 25 December, a date that currently corresponds with 7 January on the more widely used Gregorian Calendar (which is also when Christmas is observed in Eastern Orthodox countries such as Russia). The 25 December Nativity of Christ was alleged very early by Hippolytus of Rome (170–236) in his Commentary on Daniel 4:23: "The first coming of our Lord, that in the flesh, in which he was born at Bethlehem, took place eight days before the calends of January, a Wednesday, in the forty-second year of the reign of Augustus, 5500 years from Adam." [note 1] "Another early source is Theophilus Bishop of Caesarea (115–181): "We ought to celebrate the birth-day of our Lord on what day soever the 25th of December shall happen." [8] [note 2] However, it was not until 367 that 25 December began to be universally accepted. Before that, the Eastern Church had kept 6 January as the Nativity under the name "Epiphany." John Chrysostom, in a sermon preached in Antioch in 387, relates how the correct date of the Nativity was brought to the East ten years earlier. [9] Dionysius of Alexandria emphatically quoted mystical justifications for this very choice. 25 March was considered to be the anniversary of Creation itself. It was the first day of the year in the medieval Julian calendar and the nominal vernal equinox (it had been the actual equinox at the time when the Julian calendar was originally designed). Considering that Jesus was thought to have been conceived on that date, 25 March was recognized as the Feast of the Annunciation which had to be followed, nine months later, by the celebration of the birth of Christ, Christmas, on 25 December.

There may have been more practical considerations for choosing 25 December. The choice would help substitute a major Christian holiday for the popular Pagan celebrations surrounding the Winter Solstice (Roman Sol Sticia, the three-day stasis when the sun would rise consecutively in its southernmost point before heading north, 21, 22 and 23 December. In AD 274, Emperor Aurelian had declared a civil holiday on 25 December (the "Festival of the Birth of the Unconquered Sun") to celebrate the deity Sol Invictus. Finally, joyous festivals are needed at that time of year to fight the natural gloom of the season (in the Northern Hemisphere). [10]

Until the 16th century, 25 December coincided with 29 Koiak of the Coptic calendar. However, upon the introduction of the Gregorian calendar in 1582, 25 December shifted 10 days earlier in comparison with the Julian and Coptic calendars. Furthermore, the Gregorian calendar drops 3 leap days every 400 years to closely approximate the length of a solar year. As a result, the Coptic Christmas advances a day each time the Gregorian calendar drops a leap day (years AD 1700, 1800, and 1900). [11] This is the reason why Old-Calendarists (using the Julian and Coptic calendars) presently celebrate Christmas on 7 January, 13 days after the New-Calendarists (using the Gregorian calendar), who celebrate Christmas on 25 December. From AD 2101, the Coptic Christmas will be on the Gregorian date of 8 January.

Date of Easter

The First Council of Nicaea (325) sent a letter to the Church of Alexandria stating “all our brethren in the East who formerly followed the custom of the Jews are henceforth to celebrate the said most sacred feast of Easter at the same time with the Romans and yourselves and all those who have observed Easter from the beginning.” [12]

At the Council of Nicaea, it became one of the duties of the patriarch of Alexandria to determine the dates of the Easter and to announce it to the other Christian churches.Declercq, Georges (2000). Anno Domini: The Origins of the Christian Era. Isd. ISBN   978-2-503-51050-7. This duty fell on this officiate because of the erudition at Alexandria he could draw on. The rules to determine this are complex, but Easter is the first Sunday after a full moon occurring after the northern vernal equinox, which falls on or after 21 March. Shortly after Julius Caesar reformed the calendar, the northern vernal equinox was occurring on the nominal date of 25 March. This was abandoned shortly after Nicaea, but the reason for the observed discrepancy was all but ignored (the actual tropical year is not quite equal to the Julian year of 36514 days, so the date of the equinox keeps creeping back in the Julian calendar).

Between the Catholic Church and the Orthodox Church, there are different dates for holidays. In recent years there have been multiple attempts to unify these dates. Some people are skeptical about the success of these attempts. Eastern Orthodox use the Julian calendar while Catholics use the Gregorian calendar. Pope Tawadros, the Coptic pope, and Pope Francis, the Catholic pope, agreed to the proposal to celebrate Easter on the same day. Pope Tawadros's suggested to celebrate Easter on the second Sunday of April.

Coptic months

The following table refers to dates for Coptic years not containing February 29. Such years are preceded by a Coptic leap day at the end of the preceding year. This causes dates to move one day later in the Julian and Gregorian Calendars from the Coptic New Year's Day until the leap day of the Julian or Gregorian Calendar respectively.

Notes

  1. Correction: the actual quote from Hippolytus is "For as the times are noted from the foundation of the world, and reckoned from Adam, they set clearly before us the matter with which our inquiry deals. For the first appearance of our Lord in the flesh took place in Bethlehem, under Augustus, in the year 5500; and He suffered in the thirty-third year." [7] The insertion of "eight days..." is from "Chronography of 354" and the insertion of the "forty-second year" is from Eusebius.
  2. Another correction: Theophilus of Caesarea only said the following: "We would have you know, too, that in Alexandria also they observe the festival on the same day as ourselves. For the Paschal letters are sent from us to them, and from them to us: so that we observe the holy day in unison and together." No mention of Dec. 25th.

<span class="mw-page-title-main">Easter</span> Christian commemoration of the resurrection of Jesus

Easter, also called Pascha or Resurrection Sunday, is a Christian festival and cultural holiday commemorating the resurrection of Jesus from the dead, described in the New Testament as having occurred on the third day of his burial following his crucifixion by the Romans at Calvary c. 30 AD. It is the culmination of the Passion of Jesus Christ, preceded by Lent, a 40-day period of fasting, prayer, and penance.

Intercalation or embolism in timekeeping is the insertion of a leap day, week, or month into some calendar years to make the calendar follow the seasons or moon phases. Lunisolar calendars may require intercalations of both days and months.

The Julian calendar, proposed by Roman consul Julius Caesar in 46 BC, was a reform of the Roman calendar. It took effect on 1 January 45 BC, by edict. It was designed with the aid of Greek mathematicians and astronomers such as Sosigenes of Alexandria.

A leap year is a calendar year that contains an additional day added to keep the calendar year synchronized with the astronomical year or seasonal year. Because astronomical events and seasons do not repeat in a whole number of days, calendars that have a constant number of days in each year will unavoidably drift over time with respect to the event that the year is supposed to track, such as seasons. By inserting an additional day or month into some years, the drift between a civilization's dating system and the physical properties of the Solar System can be corrected. A year that is not a leap year is a common year.

A moveable feast is an observance in a Christian liturgical calendar which occurs on different dates in different years.

<span class="mw-page-title-main">New Year</span> Beginning of the calendar year

New Year is the time or day currently at which a new calendar year begins and the calendar's year count increments by one. Many cultures celebrate the event in some manner. In the Gregorian calendar, the most widely used calendar system today, New Year occurs on January 1. This was also the first day of the year in the original Julian calendar and the Roman calendar.

The Revised Julian calendar, or less formally the new calendar, is a calendar proposed in 1923 by the Serbian scientist Milutin Milanković as a more accurate alternative to both Julian and Gregorian calendars. At the time, the Julian calendar was still in use by all of the Eastern Orthodox Churches and affiliated nations, while the Catholic and Protestant nations were using the Gregorian calendar. Thus, Milanković's aim was to discontinue the divergence between the naming of dates in Eastern and Western churches and nations. It was intended to replace the Julian calendar in Eastern Orthodox Churches and nations. From 1 March 1600 through 28 February 2800, the Revised Julian calendar aligns its dates with the Gregorian calendar, which had been proclaimed in 1582 by Pope Gregory XIII.

Reform of the date of Easter refers to proposals to change the date for the annual celebration of Easter. These proposals include setting a fixed date or agreeing between Eastern and Western Christendom a common basis for calculating the date of Easter so that all Christians celebrate the Festival on the same day. As of 2022, no such agreement has been reached.

<span class="mw-page-title-main">New Year's Day</span> Holiday that celebrates the new year

New Year's Day is a festival observed in most of the world on 1 January, the first day of the year in the modern Gregorian calendar. 1 January is also New Year's Day on the Julian calendar, but this is not the same day as the Gregorian one. Whilst most solar calendars begin the year regularly at or near the northern winter solstice, cultures that observe a lunisolar or lunar calendar celebrate their New Year at less fixed points relative to the solar year.

<span class="mw-page-title-main">Date of Easter</span> Calculation of its date

As a moveable feast, the date of Easter is determined in each year through a calculation known as computus. Easter is celebrated on the first Sunday after the Paschal full moon, which is the first full moon on or after 21 March. Determining this date in advance requires a correlation between the lunar months and the solar year, while also accounting for the month, date, and weekday of the Julian or Gregorian calendar. The complexity of the algorithm arises because of the desire to associate the date of Easter with the date of the Jewish feast of Passover which, Christians believe, is when Jesus was crucified.

The epact, used to be described by medieval computists as the age of a phase of the Moon in days on 22 March; in the newer Gregorian calendar, however, the epact is reckoned as the age of the ecclesiastical moon on 1 January. Its principal use is in determining the date of Easter by computistical methods. It varies from year to year, because of the difference between the solar year of 365–366 days and the lunar year of 354–355 days.

The Ethiopian calendar, or Ge'ez calendar, is the official calendar in Ethiopia. It is used as both the civil calendar and an ecclesiastical calendar. It is the liturgical year for Ethiopian and Eritrean Christians belonging to the Orthodox Tewahedo Churches, Eastern Catholic Churches, and Eastern Protestant Christian P'ent'ay Churches. Most Protestants in the diaspora have the option of choosing the Ethiopian calendar or the Gregorian calendar for religious holidays, with this option being used given that the corresponding eastern celebration is not a public holiday in the western world. The Ethiopian calendar is a solar calendar that has more in common with the Coptic calendar of the Coptic Orthodox Church of Alexandria and Coptic Catholic Church, but like the Julian calendar, it adds a leap day every four years without exception, and begins the year on 29 August or 30 August in the Julian calendar. A gap of seven to eight years between the Ethiopian and Gregorian calendars results from an alternative calculation in determining the date of the Annunciation.

<i>Inter gravissimas</i> Papal document that established the Gregorian calendar

Inter gravissimas was a papal bull issued by Pope Gregory XIII on 24 February 1582. The document, written in Latin, reformed the Julian calendar. The reform came to be regarded as a new calendar in its own right and came to be called the Gregorian calendar, which is used in most countries today.

The intercalary month or epagomenal days of the ancient Egyptian, Coptic, and Ethiopian calendars are a period of five days in common years and six days in leap years in addition to those calendars' 12 standard months, sometimes reckoned as their thirteenth month. They originated as a periodic measure to ensure that the heliacal rising of Sirius would occur in the 12th month of the Egyptian lunar calendar but became a regular feature of the civil calendar and its descendants. Coptic and Ethiopian leap days occur in the year preceding Julian and Gregorian leap years.

<span class="mw-page-title-main">March equinox</span> When sun appears directly over equator

The March equinox or northward equinox is the equinox on the Earth when the subsolar point appears to leave the Southern Hemisphere and cross the celestial equator, heading northward as seen from Earth. The March equinox is known as the vernal equinox in the Northern Hemisphere and as the autumnal equinox in the Southern Hemisphere.

The controversy over the correct date for Easter began in Early Christianity as early as the 2nd century AD. Discussion and disagreement over the best method of computing the date of Easter Sunday has been ongoing ever since and remain unresolved. Different Christian denominations continue to celebrate Easter on different dates, with Eastern and Western Christian churches being a notable example.

The Gregorian calendar is the calendar used in most parts of the world. It was introduced in October 1582 by Pope Gregory XIII as a modification of, and replacement for, the Julian calendar. The principal change was to space leap years differently so as to make the average calendar year 365.2425 days long, more closely approximating the 365.2422-day 'tropical' or 'solar' year that is determined by the Earth's revolution around the Sun.

<span class="mw-page-title-main">Adoption of the Gregorian calendar</span> Gradual global transition from traditional dating systems to the modern standard

The adoption of the Gregorian Calendar was an event in the modern history of most cultures and societies, marking a change from their traditional dating system to the modern dating system, the Gregorian calendar, that is widely used around the world today. Some states adopted the new calendar from 1582, some did not do so before the early twentieth century, and others did so at various dates between; however a number continue to use a different civil calendar. For many the new style calendar is only used for civil purposes and the old style calendar remains used in religious contexts. Today, the Gregorian calendar is the world's most widely used civil calendar. During – and for some time after – the change between systems, it has been common to use the terms Old Style and New Style when giving dates, to indicate which calendar was used to reckon them.

Mathematics in Ethiopia in ancient times related to various aspects of the calendar, astrology, and measurements of physical properties, such as length, weight, and distance. Ethiopians used alternate unit of measurements that differ from fundamental law. Traditionally, they employed draft animals such as goat, mule, sheep or camel, and in modern sense, they use steelyard for scaling.
