Hi,

Assume your data starts in A2 with titles on row 1, in C2 enter the formula

=DATE(YEAR($A$2),MONTH($A$2),DAY($A$2))+ROW(A1)-1

Copy this down as far as necessary to create the dates in the third column
or you can just manually enter them.

In D2 enter the following formula

=IF(ROW()=2,IF(C2<TRUNC($B$2),1,MOD($B$2,1))-MOD($A$2,1),IF(C2<TRUNC($B$2),1,MOD($B$2,1)))

and copy it down as far as necessary.


If this helps, please click the Yes button.
