Etymology
From Ancient Greek σάρος (sáros), from Akkadian 𒊹 (šar₂ /šār/, “3600, total, many, a great quantity or measure”). The modern astronomical usage is attributed to Edmond Halley, who based it on the word σάρος (sáros), defined in the Suda as "a measure and a number among Chaldeans. For 120 saroi make 2222 years according to the Chaldeans' reckoning, if indeed the saros makes 222 lunar months, which are 18 years and 6 months."
