Frequently Asked Questions

What if the End Time is earlier?

The calculator assumes the End Time is the next day. E.g., 23:00 to 01:00 is calculated as 2 hours, not -22 hours.

Does it support AM/PM?

Currently, please use the 24-hour format (e.g., 17:00 instead of 5:00 PM).

Can I calculate across multiple days?

Use the "Date Calculator" or "Age Calculator" for multi-day differences. This tool is for time-of-day duration.
