How many hours are in the 22:00-06:00 night shift?
The time 22:00-06:00 has a duration of 8 hours. The calculator automatically supports overnights. If the end time is less than the start time, the system will calculate it as a day-overnight.
What is the maximum working hours?
The Labour Protection Act stipulates that no more than 8 hours per day and 48 hours per week may be worked for general work, 7 hours per day for potentially hazardous work, and 42 hours per week for potentially hazardous work.
Does the daytime break count as working hours?
The law requires employers to provide at least 1 hours of rest between work a day, and this rest does not count as working time. This calculator subtracts the rest from working time.
