Hey guys!

Say I have a date. Let's just take todays date 05/04/2009.

And say I have numbers 0 - 6 corresponding to each day of the week ie. Sunday is 0, Monday is 1 etc.

From just knowing the day of the date, in this case 5, and that today is a Sunday, is it possible to calculate what the first day of the month was? By using the numbers that correspond to each day, of course.

So, I'll reiterate: from just knowing that its the 5th and that it's a Sunday (0), is it possible to figure out what the first day of the month was?
