Precise calendar calculations. Everything is computed instantly in your browser, no account, no data sent. Leap years and Gregorian calendar rules are handled.
Each duration is converted to minutes, summed, and the total is shown in hours and minutes and in decimal hours. You can use H:MM format or decimal values:
1:30 + 0:45 + 2:15 + 3:00 = 7 hours 30 minutes = 7.5 hours decimal, average 1:52.
Write each duration on its own line, in H:MM format (e.g. 1:30, 0:45, 2:15). The calculator adds them and shows the total in hours and minutes and in decimal hours.
Yes. A line can be 1.5 (read as 1 hour 30 minutes) or 1:30. You can mix both formats in the same list.
Divide the total minutes by 60. For example, 6 hours 30 minutes = 6.5 decimal hours.
It is the total divided by the number of durations entered — useful for the average per day, per meeting or per activity.

Enter each day’s duration on a line; the total gives your weekly hours, and the decimal form helps multiply by the rate.
Weekly timesheets, time spent on projects, the total length of a playlist, workouts or meetings.
