Q: What is 9 months before August 2028?

November 2027. Counting 9 months before August 2028 gives November 2027. Whole calendar months are counted, so the day of the month does not change: August 1 lands on November 1, the 15th on the 15th, and so on for every day of the month. August has 31 days and November has 30, so the last day of August 2028 lands on November 30 rather than spilling into December. November 2027 is Q4 of 2027 and has 30 days, starting on a Monday and ending on a Tuesday.
