Counting 18 months from June 25, 2026 gives Saturday, December 25, 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 June 25, 2026; change the year in the calculator below to count from another.
