Q: What is 18 months from August 2029?

February 2031. Counting 18 months from August 2029 gives February 2031. Whole calendar months are counted, so the day of the month does not change: August 1 lands on February 1, the 15th on the 15th, and so on for every day of the month. August has 31 days and February has 28, so the last 3 days of August 2029 land on February 28 rather than spilling into March.
