The two algorithms, worked for 1945
- Western: the Anonymous Gregorian algorithm
a=7 b=19 c=45 d=4 e=3 f=1 g=6 h=7 i=11 k=1 l=3 m=0h + l − 7m + 114 = 124, and 124 ÷ 31 = 4 remainder 0: month 4, day 0 + 1. April 1- Orthodox: Meeus’s Julian algorithm
a=1 b=6 c=7 d=28 e=4d + e + 114 = 146, and 146 ÷ 31 = 4 remainder 22: Julian April 23. Plus 13 days: May 6
