How the date 90 days from today is calculated
The start date is day 0. Day 1 is the next day, and so on. The calculator adds the number of days to the start date and lets the calendar handle months of different length and leap years.
Date after N days
Calendar days: result = start date + N days
Days ago: result = start date − N days
Business days: count forward one day at a time and skip every Saturday and Sunday until N business days are counted
Public holidays are not skipped. If a holiday falls inside the span, add one extra business day for each holiday.
