Enter a start time and end time to find the elapsed duration in hours and minutes, plus the total in minutes. Overnight spans that cross midnight are handled automatically.
Without dates, an end time before the start time is treated as the next day. Times use local time.
What does this calculator do? It finds the duration between a start time and an end time in hours and minutes, plus the total number of minutes, including spans that cross midnight.
Convert each time to minutes since midnight, then subtract the start from the end. The result is shown as hours and minutes and as a total number of minutes.
If you do not supply dates and the end time is earlier than the start time, the calculator assumes the span crosses midnight into the next day and adds 24 hours. Add a start date and end date if you want to measure across specific calendar days.
Yes. An overnight span such as 10:00 PM to 6:00 AM is measured as 8 hours, either automatically when no dates are given, or precisely when you enter the start and end dates.
