Strictly speaking, the lunar standstill is a moving position in the sky relative to the direction of Earth's axis and to the rotation of the Moon's orbital nodes (lunar nodal precession) once every 18.6 years. The standstill position does not persist over the two weeks that the Moon takes to move from its maximum (positive) declination to its ...
After one nodal precession period, the number of draconic months exceeds the number of sidereal months by exactly one. This period is about 6,793 days (18.60 years). [3] As a result of this nodal precession, the time for the Sun to return to the same lunar node, the eclipse year, is about 18.6377 days shorter than a sidereal year.
The 19-year recording period is the nearest full-year count to the 18.6-year cycle of the lunar nodes. [9] In conjunction with sea level rise caused by global warming, lunar nodal precession is predicted to contribute to a rapid rise in the frequency of coastal flooding throughout the 2030s. [10]

McWhirter's main theory was that the major of primary trend of business volume and finance is clearly pointed out by the 18.6-year cycle of the North Node as it passes through the twelve signs of the zodiac. [1] [8] During a long-term trend, the four crucial points of the stock market are reached when the Node enters the four fixed signs ...

Orbital inclination and rotation. When the Moon is 5.14° north of the ecliptic, its north pole is tilted 6.68° away from the Earth. The orientation of the plane containing the vectors normal to the orbits and the Moon's rotational axis rotates 360° with a period of about 18.6 years, whereas the Earth's axis precesses with a period of around 26,000 years, so the line-up of this illustration ...
