I have something more general from my class. Here it is:
A. Take the last two digits of the year
B. Add a quarter of this number (neglect the remainder)
C. Add the day of the month
D. Add according to the month:
Jan 1 Feb 4 March 4 April 0 May 2 June 5
July 0 Aug 3 Sept 6 Oct 1 Nov 4 Dec 6
E. Add for century
18th 4 20th 0
19th 2 21st 6
F. Divide total by 7
G. The remainder gives day of week:
Sunday 1
Monday 2
Tuesday 3
Wednesday 4
Thursday 5
Friday 6
Saturday 0
This should work for any day between the years 1700-2099. Maybe you
could figure out the exact formula you needed from this.
