Q: What is 6 months from December 2030?

June 2031. Counting 6 months from December 2030 gives June 2031. Whole calendar months are counted, so the day of the month does not change: December 1 lands on June 1, the 15th on the 15th, and so on for every day of the month. December has 31 days and June has 30, so the last day of December 2030 lands on June 30 rather than spilling into July. June 2031 is Q2 of 2031 and has 30 days, starting on a Sunday and ending on a Monday.
