Weekly Hours Calculator

Calculate hours for each day (end minus start, minus unpaid breaks), then add the seven or five daily totals. Compare the sum to 40 for common full-time overtime rules in the US.

Many employers use 40 hours per week as full time, but definitions vary by company, contract, and country. This calculator helps you establish daily duration; multiply by working days to estimate weekly hours.

Run the time span for each unique day pattern, note each day’s hours, then add. For variable shifts, sum each day’s result rather than assuming one repeated start and end time.
