formula for summing time elapsed within a certain hours

I have researched websites to try and figure out formulas to assist me with this time card and have not had success. I am trying to assist our coworkers with a way to avoid loosing track of their pay and differentials.

TimeCard.xlsx

-I have laid out the basics for the spreadsheet but need any assistance with sorting out how to find elapsed time between clock in and clock out cells being that some may clock in at night and clock out the next morning and have them work with the next criteria as well?
-How do I extract time ranges within these clock in and clock out cells to be then calculated into their respective time differential ranges?
-Lastly how would I implement the other differentials like "weekends" and "holidays"?

Any help is greatly appreciated
Thanks

You will have to decide how your log entries will be made. Either Date & time or just time only. It makes a difference. In your sample, you put the date/time in the formula itself. That's not the way.

If the shift only crosses over midnight once. Say from 22:00 Tuesday to 07:30 Wednesday, then something like:
=B1+(1*(B1<A1))-A1 will work.
If B1, the end time, is less than the start time, A1 then thats a midnight crossing. Since times in Excel are fractions of a day, always less than 1, adding 1 will add 24 hours to the off-time before subtracting the start time. It's exactly like borrowing in subtraction when the minuend is smaller than the subtrahend.
