Counting 12 months before October 2025 gives October 2024. Whole calendar months are counted, so the day of the month does not change: October 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 2024 is Q4 of 2024 and has 31 days, starting on a Tuesday and ending on a Thursday.
