Q: What is 6 months before June 2028?

December 2027. Counting 6 months before June 2028 gives December 2027. 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 2027 is Q4 of 2027 and has 31 days, starting on a Wednesday and ending on a Friday.
