Orthodox dates are given in the Gregorian calendar. The earliest Orthodox Easter in these years is April 4 (1915, 2010) and the latest May 8 (1983, 2078). In the Julian calendar Orthodox Easter runs from March 22 to April 25, as Western Easter does in the Gregorian; the distance between the calendars, 13 days from 1900 to 2099 and 14 days in 2100, moves it later on the wall calendar.

Why March 22 and April 25

Easter is the first Sunday after the Paschal full moon, and that moon is never reckoned earlier than March 21 (Wikipedia, “Date of Easter”). If the full moon falls on Saturday, March 21, Easter is the next day, March 22. At the other end the reckoned full moon is never later than April 18 (The Calendar FAQ); if April 18 is a Sunday, Easter waits a week, to April 25. How the date of Easter is calculated shows where those moons come from.

Every year from 1900 to 2100 has its own page of Easter dates, and the Easter date calculator takes any year from 1583. Observance varies by church and by country. Whether a feast is a day off work is a matter of each country’s law: Holidays lists each country’s public holidays, off the open Nager.Date database.
