1. Example:  N=The year N=1994  19   N/19 1994/19  Discard   a a=18 

2.  N=The year N=1994  100   N/100 1994/100  b b=19  c c=94 

3.  N=b N=19  4   N/4 19/4  d d=4  e e=3 

4.  N=(b+8) N=27  25   N/25 27/25  Discard   f f=2 

5.  N=(bf+1) N=18  3   N/3 18/3  g 6  Discard  

6.  N=(19a+bdg+15) N=366  30   N/30 366/30  Discard   h h=6 

7.  N=c N=94  4   N/4 94/4  i i=23  j j=2 

8.  N=(32+2e+2ihj) N=76  7   N/7 76/7  Discard   k k=6 

9.  N=(a+11h+22k) N=216  451   N/451 216/451  L L=0  Discard  

10.  N=(h+k7L+114) N=126  31   N/31 126/31  m m=4  n n=2 

M=Month in which Easter occurs
n+1=Day of month on which Easter occurs
