Q: What is 18 months before July 2026?

January 2025. Counting 18 months before July 2026 gives January 2025. Whole calendar months are counted, so the day of the month does not change: July 1 lands on January 1, the 15th on the 15th, and so on for every day of the month. Both months have enough days for every date to have a counterpart, so nothing is clamped. January 2025 is Q1 of 2025 and has 31 days, starting on a Wednesday and ending on a Friday.
