Frequently Asked Questions
Does this account for time zones?
Both times are read using your browser's local time zone. If you need a cross-timezone calculation, convert both times to the same zone first using the Time Zone Converter.
What happens if I enter the end time before the start time?
The tool shows the absolute duration between the two and lets you know the order was reversed.
