Days between dates

Pick a start and end date. We show calendar days, weeks and weekdays (Monday to Friday).

Counting rules

By default we count the days between the dates: from Jan 1 to Jan 2 is 1 day.
Tick “Include the end date” when both days count, like a two-day event on Jan 1 and Jan 2.
Weekdays are Monday to Friday; holidays are not removed.

How many days until New Year?

The end date is set to January 1 of next year by default — the result shows it.
