The two algorithms, worked for 1921
- Western: the Anonymous Gregorian algorithm
a=2 b=19 c=21 d=4 e=3 f=1 g=6 h=2 i=5 k=1 l=3 m=0h + l − 7m + 114 = 119, and 119 ÷ 31 = 3 remainder 26: month 3, day 26 + 1. March 27- Orthodox: Meeus’s Julian algorithm
a=1 b=3 c=2 d=23 e=4d + e + 114 = 141, and 141 ÷ 31 = 4 remainder 17: Julian April 18. Plus 13 days: May 1
