Re: 10 second questions
Hi ganesh;
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: 10 second questions
Hi ganesh;
Hi Devante:
I use Zellers congruence for programs, but I don't know if it is easier than what you have done:
where
h =day of the week (0 = Saturday, 1 = Sunday, 2 = Monday, ...
q = day of the month
m = month (3 = March, 4 = April, 5 = May, ..., 14 = February)
K the year of the century year mod 100
J is the century
(1969 the century would is 19)
January and February are counted as months 13 and 14 of the previous year.
It was a Monday.
I found a reference to zeller's over here. It provides much more:
