Q: What is 12 months from December 2031?

December 2032. Counting 12 months from December 2031 gives December 2032. Whole calendar months are counted, so the day of the month does not change: December 1 lands on December 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. December 2032 is Q4 of 2032 and has 31 days, starting on a Wednesday and ending on a Friday.
