The two algorithms, worked for 2023
- Western: the Anonymous Gregorian algorithm
a=9 b=20 c=23 d=5 e=0 f=1 g=6 h=15 i=5 k=3 l=3 m=0h + l − 7m + 114 = 132, and 132 ÷ 31 = 4 remainder 8: month 4, day 8 + 1. April 9- Orthodox: Meeus’s Julian algorithm
a=3 b=0 c=9 d=6 e=6d + e + 114 = 126, and 126 ÷ 31 = 4 remainder 2: Julian April 3. Plus 13 days: April 16
