About time calculator
Adding durations such as 2 h 45 m + 1 h 30 m is awkward because minutes roll over at 60. The calculator keeps a running total across rows.
Example
1 h 50 m + 2 h 25 m = 4 h 15 m. Subtract a row to take away break time.
Common uses
Totalling video lengths, tallying study sessions and summing task times for a project.
Another worked example
A study plan has three sessions of 2 h 45 m, 1 h 30 m and 0 h 50 m. Adding the minutes gives 125 minutes, which carries 2 hours into the hours column. The total is 5 hours 5 minutes.
Subtracting
To find how much of a 6-hour budget remains after 4 h 20 m, subtract: 6:00 − 4:20 = 1:40.
