Counting 18 months before June 2024 gives December 2022. Whole calendar months are counted, so the day of the month does not change: June 1 lands on December 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. December 2022 is Q4 of 2022 and has 31 days, starting on a Thursday and ending on a Saturday.
