Calculate hours worked between two times, with optional break time.
Whether you're tracking work hours for payroll, billing a client, managing shift schedules, or simply adding up time entries, our Hours Calculator makes it effortless. Enter multiple start and end time pairs, and the calculator totals them up — accounting for overnight shifts and converting the result to decimal hours for easy payroll integration.
No more manually converting 7 hours 45 minutes to 7.75 hours or adding time entries with pencil and paper. This tool does it all in seconds.
Enter your start and end times in 12-hour or 24-hour format. Add as many time entries as needed (multiple shifts, multiple days). The calculator sums all durations and presents the total in both hours:minutes format and decimal hours. Lunch/break deductions can be entered separately.
Weekly timesheet for a part-time employee:
Monday: 9:00 AM – 1:30 PM = 4h 30m
Tuesday: 2:00 PM – 7:45 PM = 5h 45m
Thursday: 8:30 AM – 3:00 PM = 6h 30m (30 min lunch break = 6h 0m)
Saturday: 10:00 AM – 4:15 PM = 6h 15m
Total: 4h30 + 5h45 + 6h00 + 6h15 = 22h 30m
Decimal: 22.5 hours
