Add or subtract days from a date

Find the date a number of days before or after a starting date, including the weekday, without daylight-saving effects.

Fill in the fields to see the result.

How does it work?

Count calendar days, including weekends, holidays and 29 February. The starting day is day 0: 1 January + 1 day = 2 January. Years: 0001–9999. Not a legal deadline calculator.
