One way:

This is based on

http://cpearson.com/excel/DateTimeWS.htm#NthDoW

=DATE(YEAR(A1),MONTH(A1),1+((N-(D=WEEKDAY(
DATE(YEAR(A1),MONTH(A1),1))))*7)+(D-WEEKDAY(DATE(YEAR(A1),MONTH(A1),1))))

Where N = nth (e.g., for F3, 1; H3, 2)
D = Day of the week (Sunday = 1)
and A1 contains the last (or any other) day of the month.
