Hours Calculator

Enter your start time and end time, and the calculator finds the elapsed duration between them, converting the result into hours and minutes. If you take an unpaid break, you can subtract it to get net working hours. The tool handles shifts that cross midnight and correctly manages the 60-minute hour, so you avoid the errors common when subtracting clock times by hand. The result is ideal for timesheets, payroll preparation, and tracking billable hours.

Yes. For a shift that begins in the evening and ends the next morning, such as 11 PM to 7 AM, the calculator recognises that the end time falls on the following day and returns the correct duration of 8 hours rather than a negative figure. This makes it reliable for night-shift workers, security rosters, hospitality, and any schedule that spans midnight.

After calculating the total span between start and end times, simply deduct the length of any unpaid break to find net hours. For example, a shift from 9 AM to 5 PM is 8 hours gross, and subtracting a 30-minute unpaid lunch leaves 7.5 paid hours. Tracking breaks correctly is important for accurate pay and for complying with working-time rules that govern rest periods.

Payroll systems often use decimal hours, where minutes are expressed as a fraction of an hour. To convert, divide the minutes by 60: 30 minutes is 0.5 hours and 15 minutes is 0.25 hours. So 7 hours and 45 minutes equals 7.75 decimal hours. The calculator can present results in this format, which makes multiplying by an hourly rate straightforward when working out pay.

It is a helpful aid for estimating worked hours and preparing timesheets, but it is intended for general informational use. Payroll involves additional considerations such as overtime rules, rounding policies, statutory breaks, and local labour laws that vary by jurisdiction and employer. Always reconcile calculated hours against your official timekeeping system and applicable regulations before they are used for actual payment.
