Q: What is 12 months before November 2029?

November 2028. Counting 12 months before November 2029 gives November 2028. Whole calendar months are counted, so the day of the month does not change: November 1 lands on November 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. November 2028 is Q4 of 2028 and has 30 days, starting on a Wednesday and ending on a Thursday.
