Intro
Use this time duration calculator to find elapsed hours and minutes between two times.

Enter a start time and end time. If the end time is earlier, the calculator treats it as the next day.
Formula
Times are converted to minutes after midnight, then subtracted.
Example calculation
09:00 to 17:30 is 8 hours and 30 minutes.

Does it handle overnight times?
