Frequently Asked Questions
How do I calculate hours between two times?
Enter a start and end time. The calculator shows the difference in hours and minutes, plus decimal hours for timesheet use.
What if the end time is the next day?
Check 'overnight' to add 24 hours when the end time is earlier than the start time (e.g., 10 PM to 6 AM = 8 hours).
How do I convert hours to decimal?
Divide minutes by 60 and add to hours. For example, 7 hours 30 minutes = 7.5 decimal hours. This calculator shows both formats.
Can I add multiple time durations?
Enter durations in the add mode to sum multiple time periods, useful for timesheets and work hours.
