What 90 days is used for
Ninety days is one of the most counted spans there is. It is the usual length of a probation period at a new job, a common return window, the term of many short-term visas, and the limit in the Schengen Area’s 90/180 rule, which allows 90 days of short stays in any 180-day period.
It is also roughly a quarter of a year, but not exactly three months: three calendar months is 89 to 92 days. When a rule says “90 days”, count days, not months.
How the date is counted
The start date is day 0. Adding 90 days moves forward one calendar day at a time, through weekends, holidays, month ends and leap days, and the date you land on is the answer.
Answer = start date + 90 days
