A lunar standstill or lunistice is when the Moon reaches its furthest north or furthest south point during the course of a month. The declination at lunar standstill varies in a cycle 18.6 years long between 18.134° and 28.725°, due to lunar precession. These extremes are called the minor and major lunar standstills.
The last minor lunar standstill was in October 2015, and the next one will be in 2034. The previous major lunar standstill was in 2006 and the most recent in December 2024. From Wikipedia
