Try the below formula and format the cell to [h]:mm

=IF(MOD(B1,1)-MOD(A1,1)"06:00",MOD(B1,1)-MOD(A1,1)+(0.5/24),
MOD(B1,1)-MOD(A1,1))

-- Thanks Jacob, but let me explain my dilema further. I have 6:30am in cell
A1 & 3:00pm in cell B1; I have both of these cells formatted as custom h:mm
AM/PM & I have C1 formatted as h:mm (in this cell is the total hours from A &
B) I have been able to add or subtract a 30 min lunch w/formulas; my question
is: can I have a formula in all affected cells(the total daily hours across a
7 day work schedule) that would add a 30 min period only to those cells that
are greater than 6 hours?
