Q: What date is 18 months from January 23, 2026?

Friday, July 23, 2027. Counting 18 months from January 23, 2026 gives Friday, July 23, 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 January 23, 2026; change the year in the calculator below to count from another.
