Q: What is 30 months from September 2030?

March 2033. Counting 30 months from September 2030 gives March 2033. Whole calendar months are counted, so the day of the month does not change: September 1 lands on March 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. March 2033 is Q1 of 2033 and has 31 days, starting on a Tuesday and ending on a Thursday.
