How it works
The tool counts calendar days between the dates, and also expresses the gap in years, months and days, and in weeks plus days. Optionally include the end date in the count.
Example
From 1 January 2026 to 31 December 2026 is 364 days (365 including the end date).

By default no; tick 'include end date' to add one day.
Does the order of the dates matter?

Are leap years accounted for?
