Morphology

spring + equinox

The meaning is directly compositional: 'equinox' denotes the event of equal day and night, and 'spring' simply specifies which occurrence. This season+event noun combination follows a regular, cross-linguistic pattern (e.g. Spanish 'equinoccio de primavera'), so a B1 learner who knows both words would readily understand it.

Etymology

Spring equinox names the day in spring around March 21 when the sun is in a position that makes day and night almost the same length, like a scale with both sides 'balanced'. That's why the spring equinox is used to mark the start of the season and the coming of longer days in the north.
