title>Hours Calculator - Add, Subtract & Calculate Time Hours
The Hours Calculator helps you calculate total hours between two times, add/subtract hours, or sum up multiple time periods. It’s perfect for tracking work hours, billing clients, managing timesheets, or simply measuring productivity.
You can use it in different ways:
Format supported: 12-hour (with AM/PM) or 24-hour clock.
Total Hours = End Time − Start Time
Convert minutes to decimals if needed:
1 hour 30 minutes = 1.5 hours
Start: 9:00 AM
End: 5:30 PM
Break: 1 hour lunch
Total = (5:30 − 9:00) − 1.0 = 7.5 hours
→ You worked 7.5 hours
