Frequently asked questions

Does the calculator include the starting date?

The displayed difference measures the elapsed calendar-day gap between the two dates. For example, Monday to Tuesday is one day.

Can daylight saving time change the result?

This calculator compares calendar dates rather than 24-hour blocks, which avoids common daylight-saving-time errors.
