Hours Calculator

Calculate the hours worked between a start time and an end time minus an unpaid break, with optional pay from an hourly rate.

About Hours Calculator

This calculator measures the duration between two clock times. It converts each time to minutes after midnight and subtracts the start from the end; if the end is earlier than the start, the shift is assumed to cross midnight and 24 hours are added. The break is then subtracted. The result is shown as hours and minutes, as decimal hours (minutes ÷ 60), and as pay (decimal hours × hourly rate) when a rate is entered.

Also known as: Time Card Calculator, Time Calculator.

Questions about Hours Calculator

How do I convert minutes to decimal hours?

Divide the minutes by 60. A shift of 7 hours 45 minutes is 7 + 45 ÷ 60 = 7.75 hours. Payroll uses decimal hours because they can be multiplied directly by an hourly rate.

Does it handle night shifts that end the next day?

Yes. If the end time is earlier than the start time, such as 22:00 to 06:00, the calculator treats the end as the following day and returns 8 hours before breaks.
