Shift Calculator
Enter shift start, scheduled length, unpaid break, and days per week. Get clock-out time including overnight, paid hours, and weekly hours.
How to use this shift calculator
The shift calculator answers “what time do I get off?” from start plus length, which is how a lot of night and 12-hour schedules are written. It is not a weekly punch card. Use Time Card when you have real clock times each day.
Formula
Worked example
A 22:00 start, 8-hour length, 30-minute break ends at 06:00 and pays 7.5 hours. Four nights = 30 weekly hours.

Frequently asked questions
What time do I clock out after an 8-hour shift from 10 PM?
22:00 + 8 hours = 06:00 the next morning.
Does the break change clock-out?
Not in this tool. Length is the scheduled span; break only reduces paid hours.
12-hour shifts?
Enter 12 for length. Overnight still wraps correctly.
