How this is calculated

Today counts as day 0, so 17 days ago is the date you reach after 17 full days back. That is how deadlines like “within 17 days” are usually read: the period ends on that date.

Business days are Monday to Friday without the 11 federal holidays (5 U.S.C. 6103). When a holiday falls on a Saturday it is observed the Friday before, on a Sunday the Monday after. Banks, courts and employers can have their own calendars.
