Eclipses repeat every 18 years or so. Is this related to the saros, where 242 sidereal periods = 223 synodic periods (18 y 11 d 8 h). But the Moon's orbit precesses with a period of 18.6 y. Or are these unrelated?
Does this help? https://en.wikipedia.org/wiki/Eclipse_cycle#Repetition_of_solar_eclipses
