What Is a Time Duration Calculator?
A time duration calculator determines the exact amount of time
between two times. Instead of manually subtracting hours,
minutes and seconds, you can enter the start and end time and
instantly calculate the duration.
This tool is useful for calculating work hours, employee shifts,
meeting durations, workout sessions, study sessions, travel
durations, project time, cooking times and other activities.
Time Duration Calculation Example
Example: 9:00 AM to 5:30 PM
The duration between 9:00 AM and 5:30 PM is 8 hours and
30 minutes. The calculator also converts the duration into
total minutes, total seconds and decimal hours.
Calculate Overnight Time
Some activities begin on one day and finish after midnight.
Examples include overnight work shifts, late-night travel,
events and sleep schedules.
Enable the overnight option when the ending time belongs to
the following day. For example, a shift from 10:00 PM to
6:00 AM represents 8 hours.
