About the Workday Hours Calculator

Enter clock-in and clock-out times and an optional unpaid lunch break in minutes. Get total hours worked (in HH:MM and decimal), regular hours (capped at 8) and overtime.

Use it to verify a timesheet, estimate paychecks, or check overtime eligibility on a single day. For multi-day timesheets, use this calculator per day and sum.

How it works

OmniWhen computes (clock-out − clock-in) − unpaid lunch break to get net minutes worked. Net hours = net minutes ÷ 60. Regular hours are capped at 8 per day; anything over is overtime. The lunch break is subtracted entirely from gross time on the clock.

Examples

In 09:00, Out 17:30, Lunch 308h 0m worked · 8h regular · 0h OT
In 09:00, Out 19:00, Lunch 609h 0m worked · 8h regular · 1h OT
In 23:00, Out 07:00 (next day), Lunch 307h 30m worked · all regular

Frequently asked questions

Does this support multi-day timesheets?

Per day only. For a week, run this calculator per day and sum the results, or use the Duration Calculator for raw totals.

How is overtime defined?

Anything over 8 hours per day. US federal rules use a 40-hour week threshold instead — adapt manually if your jurisdiction differs.

Can I omit the lunch break?

Yes — set Lunch to 0 and the calculator reports gross hours.
