What is 12 months before April 2030?

Q: What is 12 months before April 2030?

April 2029. Counting 12 months before April 2030 gives April 2029. Whole calendar months are counted, so the day of the month does not change: April 1 lands on April 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. April 2029 is Q2 of 2029 and has 30 days, starting on a Sunday and ending on a Monday.
