Hours calculator

Work out the hours and minutes between two times, for one day or a whole week.

DayStartStopBreak (min)Hours

Your files never leave your device. Everything happens in this browser tab. Nothing is uploaded, and closing the tab erases it.

How it works

  1. Type the start and stop time. 9, 9:30, 930, 5p and 17:30 all work.
  2. Take off a break in minutes if you had one. The hours appear on the row, the total on the side.
  3. Add other days if you need a weekly total, then download it if you want to keep it.

Questions

How do I calculate the hours between two times?

Take the end time minus the start time. From 8:30 am to 5:15 pm is 8 hours 45 minutes. With a 30-minute break, that’s 8 hours 15 minutes.

What about a night shift?

If the stop time is earlier than the start time, Dozo counts it as running past midnight: 10p to 6a is 8 hours.

How do I turn minutes into decimal hours for payroll?

Divide the minutes by 60: 7 hours 45 minutes is 7.75 hours. Dozo shows the total both ways, and the CSV has a decimal column.

How many hours is 9 to 5?

8 hours, or 7.5 with a 30-minute unpaid lunch.

Is my time card saved or sent anywhere?

It stays in this browser on this device, so it’s still there when you come back. Nothing is sent to anyone, and there is no account.
