The screenshot below shows an alternative format to capture time worked.
If you don't use the brackets, Excel will simply 'roll over' when the duration hits 24 hours (like a clock). The square bracket syntax tells Excel to display hour durations of greater than 24 hours. In cases where calculated time exceeds 24 hours, you may want to use a custom format like :mm. By using MOD with a divisor of 1, positive results are unchanged, but negative results (which occur when start time is greater than end time) are 'flipped' to get a correct duration.įor more details, see: How to calculate number of hours between two times Formatting time durations
This formula uses the the MOD function to handle times that cross a day boundary (midnight). Next, break time is subtracted from work time to get 'net work hours'. This is done to calculate both work time and break time. At the core, this formula subtracts start time from end time to get duration in hours.
