As with solar eclipses, the Gregorian year of a lunar eclipse can be calculated as: year = 28.945 × number of the saros series + 18.030 × number of the inex series − 2454.564. Lunar eclipses can also be plotted in a similar diagram, this diagram covering 1000 AD to 2500 AD. The yellow diagonal band represents all the eclipses from 1900 to 2100.
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 40-year-old Einstein was right. ... a total solar eclipse can happen. Ancient astronomers were aware of these points in the sky, and by the apex of Babylonian civilization, they were very good ...
Data collected during that eclipse helped scientists to accurately predict what the corona, or the sun’s hot outer atmosphere, would look like during eclipses in 2019 and 2021.
For solar eclipses, the Besselian elements are used to calculate the path of the umbra and penumbra on the Earth's surface, and hence the circumstances of the eclipse at a specific location. This method was developed in the 1820s by the German mathematician and astronomer, Friedrich Bessel , and later improved by William Chauvenet .
And the eclipse ends as the moon returns to normal brightness at 4:47 a.m. This will be the only total lunar eclipse visible from the United States in 2025. (The next one will be on March 3, 2026).
Eclipses: Astronomically and Astrologically Considered and Explained (1915) [1] is an astrological text by famous English astrologer Walter Gorn Old, otherwise known as Sepharial. The book claims to teach the readers how to predict world events with solar and lunar eclipses .
