Work Hours Calculator

Calculate hours worked between any two times — minus breaks, with overnight shifts handled — for one day or the whole week, in h:mm and payroll decimals.

Work Hours — Weekly — enter start time, end time and unpaid break for each day
Day Start End Break (min) Total

Type times like 9, 9:30a, 17:30. Breaks in minutes (30) or 0:45. Overnight shifts (10 PM → 6 AM) are handled automatically. Use + split for a second work period in a day.

How to use this calculator

  1. 1

    Enter start and end time per day

    Any format works: 7, 7:15a, 19:30. An end time earlier than the start is treated as an overnight shift.

  2. 2

    Subtract unpaid time

    Type unpaid breaks in minutes. Paid rest breaks (5–20 min) belong in your hours — leave them out of the Break column.

  3. 3

    Read hours worked

    Each day and the week total appear in h:mm and decimal. Decimal hours are what payroll uses: minutes ÷ 60.

  4. 4

    Optional: add a rate

    Gross pay with overtime split appears once you enter an hourly rate.

Just need the gap between two clock times (meetings, travel, parking)? The time duration calculator is the single-pair version of this tool.

Frequently asked questions

How do I calculate hours worked?
Subtract the start time from the end time, then subtract unpaid breaks: that is your hours worked. Example: 7:00 AM to 3:30 PM with a 30-minute lunch = 8.5 − 0.5 = 8 hours. For multiple days, calculate each day and add them — the calculator above does this for a full week at once.
How do I calculate hours worked including minutes?
Work in minutes, then convert back: (end − start in minutes − break minutes) ÷ 60 gives decimal hours. 7:38 AM to 4:11 PM with 45 minutes of breaks is 513 − 45 = 468 minutes = 7.8 hours. The tool shows both h:mm (7:48) and decimal (7.80).
How are overnight work hours calculated?
When the end time is earlier than the start time, the shift crosses midnight: count time to midnight plus time after. A 10:00 PM–6:00 AM shift is 8 hours. This calculator detects overnight shifts automatically and labels them.
What counts as hours worked under the FLSA?
All time you are required to be on duty or on the employer’s premises working — including short breaks, required training and some travel — counts as hours worked. Bona fide meal periods (30+ minutes, fully relieved) and ordinary commuting do not.
How many work hours are in a year?
Full-time is commonly 2,080 hours per year (40 hours × 52 weeks). After typical US holidays and two weeks of vacation, actual worked hours land closer to 1,880–1,950.
