Counting 18 months from April 2025 gives October 2026. Whole calendar months are counted, so the day of the month does not change: April 1 lands on October 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. October 2026 is Q4 of 2026 and has 31 days, starting on a Thursday and ending on a Saturday.
