The two algorithms, worked for 1909
- Western: the Anonymous Gregorian algorithm
a=9 b=19 c=9 d=4 e=3 f=1 g=6 h=15 i=2 k=1 l=5 m=0h + l − 7m + 114 = 134, and 134 ÷ 31 = 4 remainder 10: month 4, day 10 + 1. April 11- Orthodox: Meeus’s Julian algorithm
a=1 b=5 c=9 d=6 e=1d + e + 114 = 121, and 121 ÷ 31 = 3 remainder 28: Julian March 29. Plus 13 days: April 11
