Hi

Look at this:

=SUMPRODUCT(--(MONTH($A$2:$A$100)=1),--($B$2:$B$100="John C"))

You can change the second criteria ("John C") to a cell reference if
you have list with your 11 employees which you want to use.

person for whole month based on column A dates.

John C was assigned two tasks in Month of Jan. Usally I have about 80 tasks
for 11 employees per month.

Thank you in advance for your help.
