Practical tools for measured work
Work hours calculator
Calculate shift hours after unpaid breaks, including overnight shifts.
Calculate the layout, check the diagram, then print the result for the shop or jobsite.
Single shift
How it works
Subtract the start time from the end time, add one day only when selected, then deduct unpaid breaks. A 09:00–17:30 shift with a 30-minute unpaid break gives 8 paid hours. A shift must last between zero and 24 hours.
Current-input example
The result above uses these exact values. This snapshot is included when the page is printed so the output can be checked against the original measurements.
- Start time
- 09:00
- End time
- 17:30
- End on following day
- No
- Unpaid break minutes
- 30
Primary result: Paid duration: 8:00.
Before using the result
- Check the selected mode, units and input values before using the result.
- Read the assumptions and rounding rules; compare the worked example with your intended calculation.
- A numerical result does not supply missing context or change the stated limitations.
Limitations
These are local clock hours. A shift crossing a daylight-saving change can have a different elapsed duration. No overtime, pay rates, holiday rules or payroll rounding are applied. Breaks cannot exceed the shift.
Frequently asked questions
How do I enter an overnight shift?
Choose the start and end times, then select Yes for End on following day. For 22:30 to 06:15 with a 30-minute break, the paid duration is 7 hours 15 minutes, or 7.25 hours.
Clock-out time
How it works
Add required paid time and unpaid breaks to the clock-in time. An 8-hour paid shift starting at 09:00 with 30 unpaid minutes ends at 17:30. Results round to the nearest minute.

- Clock-in time
- 09:00
- Required paid hours
- 8
- Unpaid break minutes
- 30
Primary result: Clock-out time: 17:30.
Before using the result
- Check the selected mode, units and input values before using the result.
- Read the assumptions and rounding rules; compare the worked example with your intended calculation.
- A numerical result does not supply missing context or change the stated limitations.
Limitations
The total shift must not exceed 24 clock hours. This planning calculation does not adjust for daylight-saving changes or apply payroll policy.
Frequently asked questions
Can the end time fall on the next day?
Yes. Additional calendar days is 1 when the calculated end passes midnight; otherwise it is 0.
Seven-day timecard
Enable the days worked, enter each shift and deduct unpaid breaks. Overnight means the end is on the following day. Totals use unrounded minutes; CSV includes every row and the total.
Local clock-hour totals do not account for daylight-saving transitions, overtime, pay rates or holiday rules. Use the date-and-time duration calculator when actual elapsed hours cross a clock change.
