Assuming dates are in B2:B13 and "a" and "b" are in C2:C13, try:

=SUMPRODUCT(--(B2:B13=DATE(2007,2,20)),
--(B2:B13<=DATE(2007,2,23)),--(C2:C13="a"))

=SUMPRODUCT(--(B2:B13=DATE(2007,2,20)),
--(B2:B13<=DATE(2007,2,23)),--(C2:C13="b"))


Of course, you could use cell references for the following items:
DATE(2007,2,20)
DATE(2007,2,23)
"a"
"b"
