How to display negative time in excel cell

While working with excel application I found that if we find difference between 2 times is negative then excel doesn’t display time, it shows “##########” instead of values. For positive difference we don’t have any issue.

There are 2 ways to handle this, using 1904 date system and other using custom formula.

To change the date system you need open Advance options of excel and enable the 1904 date system box.

Use the formula:

=IF(D2-A2<0, "-" & TEXT(ABS(D2-A2),"hh:mm"), D2-A2)
