The two algorithms, worked for 2010

Western: the Anonymous Gregorian algorithm
a=15 b=20 c=10 d=5 e=0 f=1 g=6 h=9 i=2 k=2 l=4 m=0
h + l − 7m + 114 = 127, and 127 ÷ 31 = 4 remainder 3: month 4, day 3 + 1. April 4
Orthodox: Meeus’s Julian algorithm
a=2 b=1 c=15 d=0 e=0
d + e + 114 = 114, and 114 ÷ 31 = 3 remainder 21: Julian March 22. Plus 13 days: April 4

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), each read September 28, 2026.
