A saros cycle of Solar Eclipses encompasses 70 solar eclipses over a period of 1200 to 1400 years. A saros cycle of Lunar Eclipses encompasses around 45 lunar eclipses over a period of around 800 years. The long periods of time involved make the saros cycle interesting for astrological interpreters of history.

Why is the Saros cycle different than the 1999 Eclipse?

This is because the saros cycle is actually 6,585.32 days long — that extra 0.32 of a day means that the earth sneaks in an extra ⅓ of a spin on its axis. The second difference is that the Great American Eclipse took place very slightly to the south of the 1999 event. The reason for this is that the saros cycle is not perfect.

These numbers are from 1 to 19 and are allocated not by order of birth but by actual years in which the Saros Series will produce an eclipse. The system labels two series as Saros Series 1 South and Saros Series 1 North because they will both be producing eclipses within six months of each other.
