Q: What is 18 months from October 2029?

April 2031. Counting 18 months from October 2029 gives April 2031. Whole calendar months are counted, so the day of the month does not change: October 1 lands on April 1, the 15th on the 15th, and so on for every day of the month. October has 31 days and April has 30, so the last day of October 2029 lands on April 30 rather than spilling into May. April 2031 is Q2 of 2031 and has 30 days, starting on a Tuesday and ending on a Wednesday.
