How this is calculated
Today counts as day 0, so 4 days ago is the date you reach after 4 full days back. That is how deadlines like “within 4 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.
