Q: What is 9 months from May 2030?

February 2031. Counting 9 months from May 2030 gives February 2031. Whole calendar months are counted, so the day of the month does not change: May 1 lands on February 1, the 15th on the 15th, and so on for every day of the month. May has 31 days and February has 28, so the last 3 days of May 2030 land on February 28 rather than spilling into March. February 2031 is Q1 of 2031 and has 28 days, starting on a Saturday and ending on a Friday.
