Hours Calculator
Work out the time between two clock times, for example the length of a shift, a flight or a night's sleep. If the end time is earlier than the start time, it is treated as the next day.

Decimal hours
Timesheets and payroll systems often need hours as a decimal number. Divide the minutes by 60: 7 hours 30 minutes is 7.5 hours, 7 hours 45 minutes is 7.75 hours, and 7 hours 20 minutes is about 7.33 hours. The calculator shows both forms.
Crossing midnight
A night shift from 22:00 to 06:00 is 8 hours. Because the end time is earlier than the start, the calculator adds a day automatically. For periods longer than 24 hours, use days between dates.
