3 durations · 2.5 hours
How to use sum durations
Enter one duration per line to total a playlist, video sequence, or schedule. Blank lines are ignored. Hours can exceed 24, so long projects do not wrap back to zero.
Worked example
0:30:00, 1:15:00, and 0:45:00 total 2:30:00, or 2.5 hours.
What the result means
Negative durations subtract from the total. Only duration values are accepted; leave task names out of the list.
