Q: What is 9 months before November 2028?

February 2028. Counting 9 months before November 2028 gives February 2028. Whole calendar months are counted, so the day of the month does not change: November 1 lands on February 1, the 15th on the 15th, and so on for every day of the month. November has 30 days and February has 29, so the last day of November 2028 lands on February 29 rather than spilling into March.
