Time
Hours Between Calculator
Find the number of hours and minutes between two times of day, even across midnight.
How the calculation works
Converts both times to minutes since midnight and subtracts. If the end time is earlier than the start time, like a shift from 10 PM to 6 AM, it assumes the end time falls on the next day and adds 24 hours automatically rather than returning a negative result.
Formula
Minutes Between = End Time − Start Time (in minutes since midnight). If negative, add 24 hours, treating the end time as occurring the next day.
Examples
9:00 AM to 5:30 PM
8 hours 30 minutes (8.50 decimal hours)
10:00 PM to 6:00 AM (overnight)
8 hours 0 minutes (8.00 decimal hours)
