Q: What is 18 months before August 2026?

February 2025. Counting 18 months before August 2026 gives February 2025. 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 2026 land on February 28 rather than spilling into March. February 2025 is Q1 of 2025 and has 28 days, starting on a Saturday and ending on a Friday.
