About the Time Difference Calculator
The Time Difference Calculator computes the duration between two times in HH:MM or HH:MM:SS format. If the end time is smaller, it is treated as crossing midnight (adds 24 hours). The result is in hours-minutes-seconds plus totals.
Useful for work hours, shift durations, and scheduling.
