What is 12 months before August 2031?

Q: What is 12 months before August 2031?

August 2030. Counting 12 months before August 2031 gives August 2030. Whole calendar months are counted, so the day of the month does not change: August 1 lands on August 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. August 2030 is Q3 of 2030 and has 31 days, starting on a Thursday and ending on a Saturday.
