The two algorithms, worked for 1983
- Western: the Anonymous Gregorian algorithm
a=7 b=19 c=83 d=4 e=3 f=1 g=6 h=7 i=20 k=3 l=5 m=0h + l − 7m + 114 = 126, and 126 ÷ 31 = 4 remainder 2: month 4, day 2 + 1. April 3- Orthodox: Meeus’s Julian algorithm
a=3 b=2 c=7 d=28 e=6d + e + 114 = 148, and 148 ÷ 31 = 4 remainder 24: Julian April 25. Plus 13 days: May 8
