The shorter array** version is slightly more efficient:

=MIN(IF((A2:A14=D1)*(A2:A14<=E1),B2:B14))

** array formulas need to be entered using the key combination of
CTRL,SHIFT,ENTER (not just ENTER). Hold down both the CTRL key and the SHIFT
key then hit ENTER.

Data in A2:B14
D1: holds early date
E1: holds later date

=MIN(INDEX(10^10-(A2:A14=D1)*(A2:A14<=E1)*(10^10-B2:B14),))

Just press ENTER
