End of Period:

I do not believe this formula works all the time. Unless I am wrong, it
fails for dates like 2/28/2008 through 3/1/2008, 3/29/2008 through
4/1/2008,
4/29/2008 through 5/1/2008, and so on.

You're correct, and <slap upside the face I've made that same %$#^&$
mistake
before.

Should be:

=A1-DAY(A1)+39-DAY(A1-DAY(A1)+32)-WEEKDAY(A1-DAY(A1)+39-DAY(A1-DAY(A1)+33))

I think there are still problems with that one too. Try the first of each
month (2/1/2008, 3/1/2008, 4/1/2008, etc.)

Rick

I don't see that.

2/1/2008 -- Sunday 3/2/2008, which is the same result as your longer formula
gives.

Given that the OP's definition results in overlapping, I wonder what it is used
for.
