The two algorithms, worked for 1958

Western: the Anonymous Gregorian algorithm
a=1 b=19 c=58 d=4 e=3 f=1 g=6 h=13 i=14 k=2 l=2 m=0
h + l − 7m + 114 = 129, and 129 ÷ 31 = 4 remainder 5: month 4, day 5 + 1. April 6
Orthodox: Meeus’s Julian algorithm
a=2 b=5 c=1 d=4 e=5
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), each read September 28, 2026.
