The two algorithms, worked for 2031

Western: the Anonymous Gregorian algorithm
a=17 b=20 c=31 d=5 e=0 f=1 g=6 h=17 i=7 k=3 l=5 m=0
h + l − 7m + 114 = 136, and 136 ÷ 31 = 4 remainder 12: month 4, day 12 + 1. April 13
Orthodox: Meeus’s Julian algorithm
a=3 b=1 c=17 d=8 e=1
d + e + 114 = 123, and 123 ÷ 31 = 3 remainder 30: Julian March 31. Plus 13 days: April 13

How the date of Easter is calculated explains each letter. The dates on this page agree with the US Census Bureau table (Western), the 5ko.free.fr tables (Western and Orthodox), Wikipedia’s list of dates for Easter (Western and Orthodox), each read September 28, 2026.
