Q: What is 6 months before November 2030?

May 2030. Counting 6 months before November 2030 gives May 2030. Whole calendar months are counted, so the day of the month does not change: November 1 lands on May 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. May 2030 is Q2 of 2030 and has 31 days, starting on a Wednesday and ending on a Friday.
