Q: What is 6 months before June 2029?

December 2028. Counting 6 months before June 2029 gives December 2028. Whole calendar months are counted, so the day of the month does not change: June 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 2028 is Q4 of 2028 and has 31 days, starting on a Friday and ending on a Sunday.
