'festival' is the definition.

Can you help me to learn more?

(Other definitions for pass over that I've seen before include "Jewish festival celebrating escape from Egypt" , "Jewish spring festival" , "Disregard - Jewish festival" , "Religious feast" , "'Jewish festival, celebrates the exodus out of Egypt (8)'" .)
