Frequently Asked Questions

Can it handle times that cross midnight?
Yes, if the start time is later than the end time, the calculator automatically recognizes it as crossing midnight and calculates accordingly.
Can I see the result in minutes or seconds only?

Can I add up multiple time durations?
The current version calculates the duration between two times. For summing multiple durations, calculate each individually and add the results.
