Frequently asked questions
How do I calculate hours worked?
Subtract the start time from the end time, then subtract unpaid breaks. 9:00 to 17:30 with a 30-minute break is 8 hours.
How are night shifts counted?
If the end time is earlier than the start time, the shift is treated as ending the next day. 22:00 to 06:00 is 8 hours.
How do I convert minutes to decimal hours?
Divide the minutes by 60. 45 minutes is 0.75 hours, so 8 h 45 min is 8.75 hours.
