I have a series of columns for date, total project hours, and hours per team
(three different teams - one column each).

what I want to do is get averages for each team hour column based on date
ranges. i.e. - during this six month period, this team averaged this number
of hours.

what I need help doing is how do I get excel to search the date column,
collect the corresponding team hours for entries that fall within a defined
range of dates, and then average those hours? I'm assuming it would be a
multiple step process and not a single formula, but my biggest roadblock is
the first step - how to collect the hours based on the date.

Any help anyone can offer will be greatly appreciated!

Thanks
