8 Hour Shift Calculator
The 8-hour shift calculator is a handy tool that helps employees and managers accurately track the length of a shift, including any breaks that may be taken. This is beneficial for scheduling, timekeeping, and ensuring labor law compliance.
With this 8-hour shift schedule calculator, you can input the start time of your shift, along with the length of any breaks, and it will calculate exactly when your shift is over.
How to Use the 8-Hour Shift Calculator
It's simple and easy to find when your shift is over:
- Choose your time format — 12-hour (AM/PM) for the American system or 24-hour for the international/metric system.
- Enter the start time of your shift, for example 7:00 AM.
- Set the shift duration. We set 8 hours by default, but you can adjust it for longer or shorter shifts.
- Specify the total break duration in minutes (not included in the shift). It doesn't matter how many individual breaks you take — just enter the total. Our calculator adds break time on top of shift hours to find your true clock-out time.
- Click Calculate End Time and the calculator will instantly show when your shift ends.
For example, if you start an 8-hour shift at 7:00 AM and have 30 minutes of unpaid break, the calculator will tell you to finish your work at 3:30 PM.
How Many Breaks Are Required by Law in an 8-Hour Shift?
Law specifies the total length of the break rather than the number of breaks, and requirements depend on:
- The state or country you live in
- How long the shift is
- The type of work
Check the official U.S. Department of Labor website to find out what the legal break for an 8-hour shift is in your state. In the USA, it's typically between 20 minutes and 1 hour.
How Long of a Break for an 8 Hour Shift?
While the exact requirement varies by jurisdiction, a 30-minute unpaid meal break is the most common standard for an 8-hour shift. Some states require a paid 10-minute rest break for every 4 hours worked in addition to the meal break.

FAQs
What time does an 8-hour shift end if I start at 7 AM?
If you start at 7:00 AM and work an 8-hour shift with a 30-minute unpaid break, your shift ends at 3:30 PM (15:30 in 24-hour format).
Does break time count as part of my 8-hour shift?
Unpaid breaks are typically not counted as part of the 8 working hours. This calculator adds break time on top of your shift duration to find your actual clock-out time.

Yes! Simply change the shift duration field to any value — 10 hours, 12 hours, or any custom amount. The calculator works for any shift length.
What if my shift goes past midnight?
The calculator handles overnight shifts automatically. If your end time crosses midnight, it will display the correct time and indicate that you finish the next day.
