Hours Between Times
Duration between a start and end time of day, including overnight.
About Hours Between Times
The duration in minutes comes from subtracting the start clock from the end clock, adding a full day when the span crosses midnight. Shifts and sessions that cross midnight need the added day, otherwise the duration would come out negative.
Formula
Hours Between Times
Duration = end time - start time, plus 24 hours if the end is past midnight
- overnight
- End times earlier than start indicate the next day
