How It Works

The calculator converts each time to minutes after midnight, handles overnight spans, subtracts break minutes, then displays hours, decimal hours, and total minutes.

Example

From 09:00 to 17:30 with a 30-minute break is 8h 0m, or 8.00 decimal hours.

Frequently Asked Questions

Can this calculate overnight durations?

Yes. If the end time is earlier than the start time, the calculator treats it as ending on the next day.

Can I subtract break time?

Yes. Add break minutes and the tool subtracts them from the total duration.

Does this include dates or time zones?

No. This tool is for simple clock-time duration. Use date or timezone tools for calendar-based planning.
