The two algorithms, worked for 1923
- Western: the Anonymous Gregorian algorithm
a=4 b=19 c=23 d=4 e=3 f=1 g=6 h=10 i=5 k=3 l=0 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=3 b=5 c=4 d=1 e=3d + e + 114 = 118, and 118 ÷ 31 = 3 remainder 25: Julian March 26. Plus 13 days: April 8
