Days From Today

Enter a number of days and choose whether to look forward ("from today") or backward ("ago"). The calculator instantly shows the resulting date and day of the week. The arithmetic uses the proleptic Gregorian calendar — including the leap-year rule that adds February 29 every four years with a centurial exception every 100 years and a counter-exception every 400 years.
