Q: What is 12 months before May 2029?

May 2028. Counting 12 months before May 2029 gives May 2028. Whole calendar months are counted, so the day of the month does not change: May 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 2028 is Q2 of 2028 and has 31 days, starting on a Monday and ending on a Wednesday.
