Time and work-hour calculations
Time & Work tools help turn clock times into clear durations and weekly totals. They are useful for personal records, timesheet checks and basic planning when you need elapsed hours rather than just start and end times.
Choosing the right calculator
The Work Hours Calculator is best for one shift or time interval, while the Time Card Calculator is better for combining several daily shifts into a weekly total. Payroll, overtime and rounding rules should still be checked against the policy that applies to you.
- Calculate one shift after subtracting an unpaid break.
- Add daily entries into a weekly time-card total.
- Use decimal-hour results when another calculation requires hours as a number.
