What is 12 months before January 2025?

Q: What is 12 months before January 2025?

January 2024. Counting 12 months before January 2025 gives January 2024. Whole calendar months are counted, so the day of the month does not change: January 1 lands on January 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. January 2024 is Q1 of 2024 and has 31 days, starting on a Monday and ending on a Wednesday.
