How it works

Calculate elapsed hours, including overnight periods. Fill in the form and choose Calculate. It opens with an example already filled in, so you can see how it works first.

What you need

Start time
End time
Unpaid break (minutes)

What you get

Duration, Decimal hours
Copy or save the result

Example

The tool opens with Start time: 09:00; End time: 17:30; Unpaid break (minutes): 30.

That gives: Duration: 8h 0m; Decimal hours: 8.

Good to know

An earlier end time means the next day; identical times mean zero hours. Does not account for daylight-saving changes.
