Frequently Asked Questions

Does the calculator include the start and end dates?
It returns the exclusive count — i.e. the number of days between the two dates. If you need an inclusive count (counting both endpoints), add 1 to the result.
Are leap years handled correctly?
Yes. The calculation uses the browser's native Date API, which accounts for leap years and varying month lengths automatically.
Can I calculate dates in the past?
Yes — pick any historical date as the start, and any later date as the end. The tool also works for future dates if you want a countdown.
