Q: What is 9 months before January 2024?

April 2023. Counting 9 months before January 2024 gives April 2023. Whole calendar months are counted, so the day of the month does not change: January 1 lands on April 1, the 15th on the 15th, and so on for every day of the month. January has 31 days and April has 30, so the last day of January 2024 lands on April 30 rather than spilling into May. April 2023 is Q2 of 2023 and has 30 days, starting on a Saturday and ending on a Sunday.
