The two algorithms, worked for 1997
- Western: the Anonymous Gregorian algorithm
a=2 b=19 c=97 d=4 e=3 f=1 g=6 h=2 i=24 k=1 l=6 m=0h + l − 7m + 114 = 122, and 122 ÷ 31 = 3 remainder 29: month 3, day 29 + 1. March 30- Orthodox: Meeus’s Julian algorithm
a=1 b=2 c=2 d=23 e=0d + e + 114 = 137, and 137 ÷ 31 = 4 remainder 13: Julian April 14. Plus 13 days: April 27
