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.

Last week’s solar eclipse shows us how far we have come in our understanding of nature. We now predict eclipses with precision. The calculations of modern astronomy are obviously superior to ...

Solar (and lunar) eclipses therefore happen only during eclipse seasons, resulting in at least two, and up to five, solar eclipses each year, no more than two of which can be total. [ 2 ] [ 3 ] Total eclipses are rarer because they require a more precise alignment between the centers of the Sun and Moon , and because the Moon's apparent size in ...
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 .
The total solar eclipse occurring on April 8 is expected to trace a wider path and last longer than the previous total solar eclipse that crossed the US in 2017. Why the 2024 eclipse will be a ...
