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]
The Moon's maximum and minimum declination vary because the plane of the Moon's orbit around Earth is inclined by about 5.14° with respect to the ecliptic plane, and the spatial direction of the Moon's orbital inclination gradually changes over an 18.6-year cycle, alternately adding to or subtracting from the 23.5° tilt of Earth's axis.
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 number of solar orbits (years) during one lunar nodal precession period equals the period of orbit (one year [ specify ] ) divided by this difference, minus one: 365.2422 / 18 ...

There will be 230 lunar eclipses in the 21st century (2001–2100): 87 penumbral, 58 partial and 85 total. [1] Eclipses are listed in sets by lunar years, repeating every 12 months for each node. Ascending node eclipses are given a red background highlight.
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 ...
The saros (/ ˈ s ɛər ɒ s / ⓘ) is a period of exactly 223 synodic months, approximately 6585.321 days (18.04 years), or 18 years plus 10, 11, or 12 days (depending on the number of leap years), and 8 hours, that can be used to predict eclipses of the Sun and Moon.
The term lunar month usually refers to the synodic month because it is the cycle of the visible phases of the Moon. Most of the following types of lunar month, except the distinction between the sidereal and tropical months, were first recognized in Babylonian lunar astronomy .
