Hours Calculator
Time cards and durations, added up.
Runs in your browserAbout
Hours Calculator covers three related jobs: a weekly time card with per-shift start/end times, breaks, and daily/weekly overtime split out automatically; a simple duration between two times (handling shifts that cross midnight); and a free-form list where each line is a duration like "1:30", "45m", or "2h 15m" that gets summed. The time card supports hourly-rate pay calculation and exports to CSV or a print-friendly view. Every result is shown in both h:mm and decimal hours, since payroll systems tend to want one or the other. Runs entirely in your browser.
Frequently asked
- How does it split daily vs. weekly overtime?
- Daily overtime (anything over 8 hours in a single shift) is calculated first; whatever remains in the regular-hours pool is then checked against the weekly 40-hour threshold, with any excess counted as weekly overtime.
- Does it handle a shift that crosses midnight?
- Yes, an end time earlier than the start time is treated as the next day, both in the time card and in the "between two times" mode.
- Can I export the time card?
- Yes, as a CSV download, a copyable table, or a print-friendly view with the browser chrome hidden.
