Any excel gurus out there wanna help me with a situation?

I'm working on a document that has two main tables. Table A has columns for Contributor Name, how much time they contributed at any one date, and the individual dats of each contribution. Each row in the table is a person, a date, and a quantity of time for that date. Table B then takes that data and makes additional calculations based on time, month, and other factors.

What I'm trying to do is this: In a single cell within Table A, I need to sum the total time for each contributor within a single month. What would be the most effective formula to do this?
