Counting 18 months before August 2024 gives February 2023. 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 2024 land on February 28 rather than spilling into March. February 2023 is Q1 of 2023 and has 28 days, starting on a Wednesday and ending on a Tuesday.
