Measure the exact time between two dates and moments — shown as days, hours and minutes, plus total hours.
About this Time Duration Calculator
Time Duration Calculator measures the exact gap between two moments — start and end of a shift, a project, a trip or a countdown to a deadline. The result is broken into days, hours and minutes and also given as total hours and total minutes, which is what timesheets and billing usually need.
How to use it
- Enter the start date and time.
- Enter the end date and time.
- Press Calculate duration.
- Read the breakdown, plus totals in hours and minutes.
Example
From Friday 6:00 PM to Sunday 9:30 AM is 1 day, 15 hours and 30 minutes — 39.50 hours in total.
Frequently asked questions
What if the end is earlier than the start?
The tool still reports the size of the gap and flags that the end comes first, so swapped entries are easy to spot.
Does it handle overnight shifts?
Yes — because full dates are used, a shift from 10 PM to 6 AM the next day correctly counts as 8 hours.
