8-Hour Shift Calculator
Enter your shift start time and any unpaid break to find out exactly when your 8-hour shift ends.
What this calculator does
The 8-Hour Shift Calculator figures out exactly what time your shift ends, based on when you clock in and how long your unpaid break is. It also shows the total time you’ll spend on site once the break is included.
How the calculation works
The calculator starts from your clock-in time, adds a fixed 8 hours of work, then adds any unpaid break minutes on top (since unpaid breaks extend your time on site without counting as worked hours). The result wraps around midnight automatically if your shift crosses into the next day.
This tool is for general scheduling and planning purposes. Always confirm your exact scheduled hours and break policy with your employer, since some workplaces count breaks differently.
