Find the exact length of a day or overnight shift from clock-in and clock-out times.
A shift from 7:00 AM to 3:30 PM is 8 hours 30 minutes.
The calculator keeps each component visible so you can review inputs instead of relying on one unexplained total.
Find the exact length of a day or overnight shift from clock-in and clock-out times. It can help employees, shift workers, freelancers, supervisors and small-business owners make quick planning estimates before reviewing an official time card or payroll statement.
Results can be formatted for USD, GBP, CAD, AUD, EUR or NZD when money is involved. Currency formatting does not apply tax, minimum-wage, overtime or employment-law rules automatically.
Enter the requested values and select Calculate. The tool applies this method: Shift length = end time − start time, adding 24 hours when the shift crosses midnight.
The result is a planning estimate. Employer policies, contracts, taxes and employment laws can change the final amount.
