MyCalculatorHow it works
Duration is the difference between end time and start time, in minutes, converted to hours and minutes. If the end time is before the start time, we add 24 hours, assuming the span crosses midnight.
Example
From 09:15 to 17:45 is 8 hours 30 minutes.
Assumptions & limitations
This assumes a single continuous span, not multiple days — for spans longer than 24 hours, use the date difference calculator alongside this one.
Frequently asked questions
What if my shift crosses midnight?
Enter your start and end time as normal — if end is earlier than start, we treat it as ending the next day.
