Title: List of dates for Easter
Content:  In 1943 Easter fell on Sunday, April 25. The last ecclesiastical full moon preceding the Paschal did not occur until Saturday, March 20; prior to March 21, the fixed date to which the vernal equinox is assigned for the purposes of the computus, meaning the Paschal full moon did not happen until Sunday, April 18. Consequently, Easter was the following Sunday (April 25). Easter will next occur as late again in 2038—a span of 95 years. The second latest date for Easter, April 24, occurred in 2011. The last time this occurred was in 1859 and will not happen again until 2095—spans of 152 and 84 years. Easter last occurred on April 23 in 2000 and will not occur on that day again until 2079, a span of 79 years.

Content:  moon would fall on 19 April, and Easter could be as late as 26 April. In the Julian calendar the latest date of Easter was 25 April, and the Gregorian reform maintained that limit. So the paschal full moon must fall no later than 18 April and the new moon on 5 April, which has epact label "xxv". 5 April must therefore have its double epact labels "xxiv" and "xxv". Then epact "xxv" must be treated differently, as explained in the paragraph above. As a consequence, 19 April is the date on which Easter falls most frequently in the Gregorian calendar:

Content:  The earliest dates for Easter in the Eastern Orthodox Church between 1875 and 2099 are April 4, 1915 and April 4, 2010 (Gregorian). Both dates are equivalent to 22 March in the Julian Calendar.

Content:  In 1818 the Paschal Full Moon fell on Saturday, March 21 (the equinox). Therefore, the following day, March 22, was Easter. It will not fall as early again until 2285, a span of 467 years. The next earliest Easter between 1818 and 2285 (March 23) occurred in 1845, 1856, 1913 and 2008, and will not occur again until 2160—an 11, 57, 95 and 152-year gap, respectively. Easter last occurred on March 24 in 1940 and will not occur on that day again until 2391, a 451-year gap.
Title: List of dates for Easter
Content:  Despite using calendars that are apart by 13 days, Western Easter and Orthodox Easter occasionally fall on the same date as it did 2010, 2011, 2014, and 2017. For example, according to the Western (Gregorian) calendar, the first Paschal Full Moon after the Spring Equinox (March 21) fell on Monday, April 14, 2014. The following Sunday, April 20, was, therefore, Easter Day. According to the Orthodox (Julian) calendar (which is 13 days behind the Gregorian calendar), the Spring Equinox also falls on March 21. However, in the Gregorian Calendar, this is April 3. The first Orthodox Full Moon after the Equinox falls on (Julian) Tuesday, April 2, 2014 (Gregorian April 15). The following Sunday, (Julian) April 7, is, therefore, Easter Day (Gregorian April 20).

These new dates, however, would be extremely uncommon: commencing calculations from 1997, the first occurrence of Easter on 26 April would be in 2201 (a year in which under the Gregorian method Easter falls on 19 April), while the first

The Gregorian calculation of Easter was based on a method devised by the Calabrian doctor Aloysius Lilius (or Lilio) for adjusting the epacts of the Moon, and has been adopted by almost all Western Christians and by Western countries which celebrate national holidays at Easter. For the British Empire and colonies, a determination of the date of Easter Sunday using Golden Numbers and Sunday letters was defined by the Calendar (New Style) Act 1750 with its Annexe. This was designed to match exactly the Gregorian calculation.

Since the Julian calendar is no longer used as the civil calendar of the countries where Eastern Christian traditions predominate, Easter varies between 4 April and 8 May in the Gregorian calendar. Also, because the Julian "full moon" is always several days after the astronomical full moon, the eastern Easter is often later, relative to the visible Moon's phases, than western Easter. Among the Oriental Orthodox, some churches have changed from the Julian to the Gregorian calendar and the date for Easter, as for other fixed and moveable feasts, is the same as in the Western church.
Title: Perennial calendar
Content:  The Christian celebration of Easter is historically calculated to occur on the first Sunday after the first ecclesiastical full moon falling on or after 21 March. In leap-week calendars, March 21 is less likely to match astronomical spring equinox than in the Gregorian calendar. The Symmetry454 calendar proposes Sunday, April 7 as a permanently fixed date for Easter, based on the median date of the Sunday after the day of the astronomical lunar opposition that is on or after the day of the astronomical northward equinox, calculated for the meridian of Jerusalem. In 1963 the Second Ecumenical Council of the Vatican declared: ""[The Vatican] would not object if the feast of Easter were assigned to a particular Sunday of the Gregorian Calendar... [and] does not oppose efforts designed to introduce a perpetual calendar into civil society."" - Second Ecumenical Council of the Vatican
