Counting 40 weeks before February 29, 2028 gives Tuesday, May 25, 2027. Every calendar day is counted, including weekends and public holidays, and leap days are handled exactly. The day you start on is not counted; the day you land on is. February 29 only exists in a leap year, so this counts from 2028, the next one.
