Days Between Dates Calculator

Calculate the number of calendar days between two dates. Enter a start and end date for an immediate result.

How it works

This tool subtracts the start date from the end date. It excludes the starting day, uses calendar dates rather than elapsed hours, and returns a negative result when the end date is earlier. For example, 1 January to 2 January is one day. Public holidays and weekends are not excluded.
