The lunar standstill phenomenon was probably known from Megalithic times. In high latitudes, there was a period within the 18.6 years cycle, when the Moon became circumpolar. [4] It would have drawn the attention of locals. In other latitudes, the major lunar standstill featured constant scene illumination during the full Moon.
Lunar standstill: every 18.6 years, the declination range of the Moon reaches a maximum or minimum. Lunar precession is a term used for three different precession motions related to the Moon . First, it can refer to change in orientation of the lunar rotational axis with respect to a reference plane , following the normal rules of precession ...
A standstill is a situation of no movement or activity. Standstill may refer to: Lunar standstill, a time at which the range of the Moon's declination is at a maximum or minimum; Standstill (band), a Spanish post-hardcore-band; Standstill (bicycle), a technique used by bicycle riders; Standstill agreement, an instrument of a hostile takeover ...
The last full moon of the year will rise overnight in a rare “major lunar standstill” amid a dazzling meteor shower. The “cold moon” - a phenomenon that happens every 18.6 years - will ...
The lunar standstill is hard for a casual observer of the moon to recognize, he added, and is only really visible in detailed data on observations of the moonrise and moonset.
This is called major lunar standstill. Around this time, the Moon's declination will vary from −28°36′ to +28°36′. Conversely, 9.3 years later, the angle between the Moon's orbit and Earth's equator reaches its minimum of 18°20′. This is called a minor lunar standstill. The last lunar standstill was a minor standstill in October 2015.

The Metonic cycle is the most accurate cycle of time (in a timespan of less than 100 years) for synchronizing the tropical year and the lunar month (synodic month), when the method of synchronizing is the intercalation of a thirteenth lunar month in a calendar year from time to time. [20]
