Time Duration Calculator
Calculate elapsed time between two moments or adjust a time by adding/subtracting hours, minutes, and seconds.
Worked Example:
If you started a project on Jan 15, 2024 at 09:00 AM and finished on Jan 16, 2024 at 02:30 PM, the duration would be 1 day, 5 hours, 30 minutes.
Formula
Duration = End Time - Start Time
The time duration is calculated by subtracting the start time from the end time, resulting in the elapsed hours, minutes, and seconds. When adjusting time, we add or subtract the specified interval from the base time to get the new time.
