Q: What date is 4 months from February 29, 2028?

Thursday, June 29, 2028. Counting 4 months from February 29, 2028 gives Thursday, June 29, 2028. Calendar months are counted, so the result keeps the same day of the month where it exists. Adding a month to the 31st lands on the last day of a shorter month rather than spilling into the next one. 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.
