Regular Night Differential Hours and Night Differential OT


New Member
Good Day!
How can I compute the number of hours between a specific range,
For example, an employee has timed in at 6:00 pm then timed out at 3:00 am the next day. What formula can I use to compute the number of hours that is only within the Night Differential, 10:00 pm to 6:00 am.
Night Differential can be changed based on the policy of the user.

Thank you very much.

It works for your sample. But I'm not sure what other variations are possible, since I don't know the labor law in you area.
Ex: In my area Day shift going over 14 hours is not permitted without allowing for 13 hour before next shift, and only with written consent.

Thank you so much.

In my area, regardless of the shift, as long as your time goes between the given range of Night Differential (Mostly 10:00 pm to 6:00 am), rate will be different from the regular hour, also if you work for more than 8 hours, the excess will be considered as overtime, with a different rates.
So, if you have an overtime that goes between 10:00 pm to 6:00 am, then the rate will also be different from the regular overtime.
We'll again, Thank you. :)
