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.
Astronomers' predictions of eclipses began in China as early as the 4th century BC; eclipses hundreds of years into the future may now be predicted with high accuracy. Looking directly at the Sun can lead to permanent eye damage, so special eye protection or indirect viewing techniques are used when viewing a solar eclipse.
18.999 eclipse years (38 eclipse seasons of 173.31 days) 238.992 anomalistic months; 241.029 sidereal months; The 19 eclipse years means that if there is a solar eclipse (or lunar eclipse), then after one saros a new moon will take place at the same node of the orbit of the Moon, and under these circumstances another solar eclipse can occur.

An eclipse season is the only time when the Sun (from the perspective of the Earth) is close enough to one of the Moon's nodes to allow an eclipse to occur. During the season, whenever there is a full moon a lunar eclipse may occur and whenever there is a new moon a solar eclipse may occur.
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.
