I'm looking for formulas that will give me the first Monday and last Sunday
of a period. For example The First Monday of February 2008 would be February
4 and the last Sunday would be March 2. Add x number of days to the formulas
to give me the first Monday in April 2008 as April 7 and the last Sunday as
May 4.

probably too complicated but it seems to work

=A1+(2<WEEKDAY(A1))*(7-WEEKDAY(A1)+2)+(2=WEEKDAY(A1))*(2-WEEKDAY(A1))-7


Your date in A1

What is your definition of a "period"?

With any date in A1, the first Monday of the month of that date is given by the
formula:

=A1-DAY(A1)+8-WEEKDAY(A1-DAY(A1)+6)

But I don't know how you are computing the "end of the period".

I interchanged the word period with month. For example the month of May 2008
would begin with April 28 and end the final Sunday would be June 1.

Now I am completely confused. I always thought that May began on May 1 and
ended on May 31; and that June and April were not in the month of May.

Your going to have to be more explicit about your calendar rules in order for
me to help you.

This isn't a calendar month but more of a complete monthly period beginning
with a Monday and ending with a Sunday.
If the calendar month ends on a Tuesday the period would continue to the end
of the week through Sunday. If the calendar month begins after a Monday the
period would begin with the preceding Monday. Also know as a broadcast month.

I'm guessing these aren't necessarily the most efficient formulas, but they
do appear to work...

First Monday of the Month
=================================
=DATE(YEAR(A1),MONTH(A1),1)-WEEKDAY(DATE(YEAR(A1),MONTH(A1),1))-7*(WEEKDAY(DATE(YEAR(A1),MONTH(A1),1))=1)+2

Last Sunday of the Month
=================================
=DATE(YEAR(A1),MONTH(A1)+1,7)-WEEKDAY(DATE(YEAR(A1),MONTH(A1)+1,7))-7*(WEEKDAY(DATE(YEAR(A1),MONTH(A1)+1,7))=1)+1

I think I have it now.

If I understand you correctly, the beginning of the period is the latest Monday
that is equal to or less the beginning of a Month.

The end of the period is the earliest Sunday that is equal to or greater than
the end of that Month.

With any date in a particular calendar month in A1:

Beginning of Period:

=A1-DAY(A1)+2-WEEKDAY(A1-DAY(A1))

End of Period:

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