Time Duration Calculator
Calculate the exact duration between two times in hours, minutes, and seconds.
About Time Duration Calculator
Designed for timesheet users, freelancers and event planners, the Time Duration Calculator opens instantly with no signup and nothing to install. Find the duration between two times on the same or next day, with the result in hours, minutes and decimal hours, which is what timesheets and billing need. The tool handles overnight spans, so a 9 pm to 2 am shift is counted correctly across midnight, and it shows both the clock duration and the decimal form that payroll systems use. Freelancers use it to log billable hours, event planners to schedule sessions, and shift workers to verify their hours, and the tool accepts 12-hour and 24-hour input. Because everything is local, the times are not uploaded. It is the clean duration maths that subtracting clock times by hand always gets wrong. Dates follow the DD/MM/YYYY convention used across India, and timezone behaviour matches how calendars and salary cycles actually run here. Typical moments to reach for it: logging billable hours for a client, scheduling event session lengths, or verifying a shift duration across midnight. Try it the next time a quick decision needs real numbers behind it.

Frequently Asked Questions
How to calculate time duration?
Subtract start time from end time. For times crossing midnight, add 24 hours. Our calculator handles both same-day and overnight duration calculations automatically.
What is elapsed time?
Elapsed time is the total time that has passed between two specific moments, measured in hours, minutes, and seconds. It's also called time duration or time interval.
How to calculate work shift duration?
Enter shift start and end times, deduct unpaid break time. Example: 9:00 AM to 6:00 PM with 1-hour break = 8 hours of work duration.
How are overnight shifts handled?
If the end time is earlier than the start, the tool assumes the shift crossed midnight and adds 24 hours to the span.
Why show decimal hours?
Payroll and billing systems use decimal hours, so 1 hour 30 minutes shows as 1.5 hours, ready to multiply by a rate.
