Hours Calculator
Calculate the total hours worked between two times. Subtract break time and see your results in both decimal hours and HH:MM format.
If end time is earlier than start time, midnight crossover is assumed.
About the Hours Calculator
This hours calculator makes it easy to find out how many hours and minutes you worked during a shift. Simply enter your start time, end time, and any break duration. The calculator handles midnight crossover automatically — so if you work a night shift from 10 PM to 6 AM, it will correctly calculate 8 hours. For tracking an entire week of shifts, try the Time Card Calculator which includes overtime and pay calculations.
Decimal hours are useful for payroll calculations — for example, 8 hours 30 minutes equals 8.5 decimal hours. Multiply by your hourly rate to get your gross pay for the shift. If you work across multiple time zones, the Time Zone Calculator can help you convert times between locations before entering them here.
