Counting 18 months before August 2025 gives February 2024. 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 29, so the last 2 days of August 2025 land on February 29 rather than spilling into March. February 2024 is Q1 of 2024 and has 29 days, starting on a Thursday and ending on a Thursday.
