I have a date such as April,1,2009. I want to know what the weekday is, i.e. whether April 1 is a Monday, Tuesday etc. Likewise I want to check weekday of each day in the month of April.

If your computer language of choice doesn't have a DayOfWeek
function, you can use Zeller's Congruence which returns the day of the week using simple integer arithmetic.
