Time Duration Calculator
Calculate the difference between two times.
What Does a Time Duration Calculator Do?
A time duration calculator computes the difference between two times in hours, minutes, and seconds. Enter a start time and end time, and the tool instantly shows the elapsed duration. This is useful for tracking work hours, calculating travel times, logging exercise sessions, and computing billable hours for freelancers.
How Do I Calculate Hours Between Two Times?
Enter the start time and end time using the time pickers or type them directly. The calculator shows the duration in hours and minutes. It handles both same-day and overnight time spans correctly, so a shift from 10 PM to 6 AM will correctly show 8 hours.
Can I Use This for Timesheet Calculations?
Yes. Enter your clock-in and clock-out times to see total hours worked. This is perfect for freelancers tracking billable hours, employees verifying timesheets, or managers calculating shift durations. Add up multiple durations to get your weekly total.
Does This Tool Handle Overnight Time Ranges?
Yes. If your end time is earlier than your start time, the calculator assumes the end time is on the following day and calculates accordingly. This correctly handles overnight shifts, red-eye flights, and any other scenario where the time range crosses midnight.
How Do I Calculate Overtime Hours?
Enter your regular shift end time as the start and your actual clock-out time as the end to calculate overtime duration. For example, if your shift ends at 5:00 PM but you worked until 7:30 PM, the calculator shows 2 hours 30 minutes of overtime. Multiply this by your overtime rate to calculate extra pay.
Can I Add Multiple Time Durations Together?
This tool calculates a single duration between two times. To add multiple durations (such as daily work hours across a week), calculate each day separately and add the results manually, or note down each duration and sum them. For a 40-hour work week, calculate each day and verify the total matches your timesheet.
