Time Card Calculator

A time card that totals itself

Punch in, punch out, lunch out, lunch in — the four-column card, totalled per day and per week, with the rounding your clock actually applies.

Questions people ask

The things that come up about time card calculators, answered plainly.

Why does my time card total differ from the clock's?

Rounding, nearly always. A clock set to quarter-hour rounding turns a 09:07 punch into 09:00 and a 09:08 into 09:15, and over a week that adds up. Set the same rule here and the totals should agree.

Can I use a 12-hour clock?

Yes — 9am, 5:30pm and 0930 are all read correctly, as is a bare 930.
