I am working on a project that requires to me find out the date of the week
for all the calender days in a year. For example, 3/2/09 - 3/8/09 falls in
the week of 3/2/09 assuming that my week starts on Monday and ends on Sunday.

I've been browsing through all the formulas and have tried many combinations
of the IF and DATE functions, but without success. Appreciate any input!

My table will look like this --- I need to compute the "week of" date,
without having to enter this information manually.
