The two algorithms, worked for 1975
- Western: the Anonymous Gregorian algorithm
a=18 b=19 c=75 d=4 e=3 f=1 g=6 h=6 i=18 k=3 l=2 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=3 b=1 c=18 d=27 e=3d + e + 114 = 144, and 144 ÷ 31 = 4 remainder 20: Julian April 21. Plus 13 days: May 4
