Saros cycle
The Saros cycle is an eclipse cycle. It is a period of about 6585 + 1/3 days (approximately 18 years 11 days) which can be used to predict eclipses of the Sun and the Moon.

The Saros cycle is an eclipse cycle with a period of about 18 years 11 days 8 hours (approximately 6585â…" days) that can be used to predict eclipses of the Sun and Moon.
Saros cycles don't last forever or indefinitely, because realignments of full Moon with its node are not perfect. A typical Saros series consists of 69 to 86 eclipses spanning well over a thousand years.

SAROS
The saros is the roughly 18-year periodic cycle of the Earth-Moon-Sun system. Every 6,585 days, the Earth, Moon and Sun are in exactly the same position. When there is a lunar eclipse, there will also be one exactly 6,585 days later.
Saros
(a) A particular cycle of similar eclipses (lunar or solar) known to the Babylonians, that recur at intervals of 6585 days (about 18 tropical years). The interval contains 223 synodic months (6585.32 days) and 19 ecliptic years (6585.

During one saros about 70 eclipses take place, usually 29 lunar and 41 solar; of the latter, usually 10 are total and 31 partial. The minimum number of eclipses that can occur in a given saros year is 2, the maximum 7, and the average is 4.

They copied the Ba by Ionian asterisms, appropriated Babylonian knowledge of the planets and their courses, and learned to predict eclipses by means of the " Saros.
Two well-known eclipse cycles are the Saros cycle and the Inex cycle. The Saros cycle is probably the most well known, and one of the best, eclipse cycles.
The most important series was the "Saros" - it said that 18 years and 11 days after an eclipse, another very similar eclipse would occur. It was probably through the Saros calculation that Thales was able to make his prediction of the solar eclipse.

For example, the ancient Babylonians understood one such set of cycles called the Saros, and were able to predict eclipses based on this knowledge. Here is a link to a discussion of such cycles and regularities in eclipse patterns.
