Q: What date is 18 months from February 27, 2026?

Friday, August 27, 2027. Counting 18 months from February 27, 2026 gives Friday, August 27, 2027. Calendar months are counted, so the result keeps the same day of the month where it exists. Adding a month to the 31st lands on the last day of a shorter month rather than spilling into the next one. The day you start on is not counted; the day you land on is. The starting date is read as February 27, 2026; change the year in the calculator below to count from another.
