Q: What is 9 months before April 2028?

July 2027. Counting 9 months before April 2028 gives July 2027. Whole calendar months are counted, so the day of the month does not change: April 1 lands on July 1, the 15th on the 15th, and so on for every day of the month. Both months have enough days for every date to have a counterpart, so nothing is clamped. July 2027 is Q3 of 2027 and has 31 days, starting on a Thursday and ending on a Saturday.
