How this calculator works
Ninety days consist of twelve weeks and six days. Three calendar months do not have a fixed ninety-day length: month-end dates and leap years change the interval. This tool answers a fixed-day count, rather than interpreting visa rules, prescriptions or statutory deadlines.
Formula
Destination = reference date + 90 calendar days. The start date is excluded from the offset.

UTC calendar dates, Gregorian calendar, years 0001–9999. Date offsets are limited to ±100,000 days. This is not a legal-deadline or holiday calendar. “Today” uses UTC and can differ from your local date near midnight.
