What date was 15 days ago?

If you count back 15 days from today, you land on Tuesday, October 13, 2026. That day was a Tuesday, day 286 of 2026, in ISO week 42. The gap is 15 calendar days (2 weeks and 1 day).

Today is not counted as day 1: the first day counted is tomorrow (or yesterday when you count back). This is how deadlines, notice periods and delivery dates are usually calculated. Between the two dates there are 11 business days, Monday to Friday, before public holidays are taken off.

The answer above uses your own time zone, so it is always correct for where you are. To count from a different start date, or to skip weekends, use the calculator below.
