Time Calculator

Add up hours and minutes, find how long it is between two times, or work out what time it will be after a duration.

Total
0:00:00

Three ways to calculate time

  • Add / subtract time: add up working hours, video lengths or lap times. Set a row to “−” to subtract it, for example a break. The total can go above 24 hours (for example 37:15:00) and is also shown in decimal hours for timesheets and payroll.
  • Time + duration: “I start at 9:00 AM and work 8 hours 30 minutes. When do I finish?” If the result passes midnight, the tool tells you it is the next day.
  • Time between: “How long from 9:30 PM to 6:15 AM?” When the end time is earlier than the start, it is taken as the next day (8 h 45 min in this example), which suits night shifts and sleep.

Decimal hours

Timesheets often need hours as a decimal: 7 hours 45 minutes = 7.75 hours, and 20 minutes = 0.33 hours. Divide the minutes by 60 to convert them yourself. To count days between dates instead of hours, use the Date Difference Calculator.
