Min Formula with IF

I need to run a min formula where if a value is "Date", then the min function is applied to only those cells where said "Date" is true. So: if the date is 7/22/2010 within column B, then I need the minimum temperature from those days that are values in column D. So, in this case = 54.777. Please, and thank you.
