Working-time calculators that show the math
Add up hours and minutes, total a time card, work out overtime pay, or convert military time. Every result comes with the sum written out, so you can see where each number came from. Nothing you type leaves your browser.
How many hours did you work today?
Leave the break empty if you didn't take one. An out time earlier than the in time means the shift crossed midnight.

Why these calculators are different
Most hour calculators hand you a number and stop there. These don't. Each one writes out the sum it did, like "9:00 on the clock - 0:30 break = 8:30", so you can check it against a pay stub or a timesheet. The overtime math follows the federal rule in 29 U.S.C. section 207, and it doesn't quietly assume state rules it can't know.
They're built for people who'd like to check their own numbers: workers who think a pay stub's short, managers who're filling in timesheets, and freelancers who've got to bill by the hour. If you're one of them, you'll find the answer and the working side by side.
Not sure where to start? If you've got clock times, start with the time card calculator. If you've only got a total, the overtime calculator's quicker. Either way, you won't need more than a minute, and you can't break anything by trying. If a result doesn't look right, that's worth knowing too, so we'd love to hear about it.
There's nothing to sign up for, and you won't find a lead form in front of the results. The math runs in your browser, so the hours and pay you enter aren't sent anywhere. If you'd like to see how a calculator works under the hood, the methodology page lists every rule and the test cases we check before each update.
