Counting 9 months before June 2026 gives September 2025. Whole calendar months are counted, so the day of the month does not change: June 1 lands on September 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. September 2025 is Q3 of 2025 and has 30 days, starting on a Monday and ending on a Tuesday.
