Equinoxes
Day and night are nearly equal length worldwide. The Sun crosses the celestial equator — a key marker for seasonal change.
Solstices
The Sun reaches its northernmost or southernmost point in the sky. These are the longest and shortest days of the year.
Your hemisphere
Dates are shown in your local timezone. Season names reflect the Northern Hemisphere — the same astronomical event marks opposite seasons south of the equator.
