Quick Answer
Subtract the start time from the end time. If the end time is earlier than the start time, add 24 hours before subtracting so overnight shifts still return a positive duration.
How to Calculate Minutes Between Two Times
- Enter the start and end times in 24-hour clock format.
- Click Calculate to convert each time into minutes after midnight.
- If the end time is earlier, the calculator assumes the next day.
- Read the result in minutes and in hours and minutes.
Formula
Minutes = (End minutes after midnight - Start minutes after midnight + 1440) mod 1440
Worked Examples
Example 1: 09:15 to 13:45 = 270 minutes = 4 hours 30 minutes.
Example 2: 22:30 to 01:10 = 160 minutes = 2 hours 40 minutes overnight.
Example 3: 08:00 to 08:00 = 0 minutes.
