Time duration calculator

Combine days, hours and minutes and get the total in minutes and decimal hours.

Worked example

1 day, 2 hours and 45 minutes equals 1,605 minutes, or 26.75 hours. To get decimal hours from minutes, divide by 60.

How to use the result

Use this for elapsed durations such as project time or a timer. Each day counts as exactly 24 hours. For time across a daylight-saving clock change, find the actual elapsed hours first. Values above 59 minutes and 23 hours are normalized in the result.
