Three consecutive months can range from 89 days (Feb-Mar-Apr in non-leap years) to 92 days (some summer combinations). For legal purposes, "90 days" and "3 months" are usually defined differently.

This depends on the specific requirement. For legal filings, many jurisdictions extend the deadline to the next business day. For visa expiration, the actual calendar date applies regardless. For employment matters, check your contract. When in doubt, complete your requirement before the weekend/holiday to be safe.
