About hours calculator
To find the hours worked in a shift, subtract the start time from the end time and take off unpaid breaks.
Example
Starting at 9:15 AM and finishing at 6:00 PM is 8 h 45 m. With a 45-minute lunch break that is 8 hours exactly.
Tips
- Use 24-hour times to avoid AM/PM mistakes.
- Overnight shifts cross midnight; the tool handles an end time earlier than the start.
- Convert minutes to decimals for payroll: 8 h 45 m is 8.75 hours.
Another worked example
A night shift from 22:00 to 06:30 lasts 8 hours 30 minutes. With a 30-minute break, the paid time is 8 hours. In decimal hours, 7 h 45 m is 7.75 hours, which is the form payroll systems usually need.
Tips
- Round the same way every day, for example to the nearest 5 minutes.
- Count unpaid breaks only once.
- Keep a record of start and end times, not only the totals.
