How do I find out how many days until a specific date?+

Enter the target date and the calculator instantly shows how many days remain until it (or how many days have passed if it's in the past).

The calculator shows how many days have passed since that date, with a clear 'since' description instead of 'until'.

How many days until Christmas?+

How many days until my birthday?+
