An equinox occurs when the Sun crosses the celestial equator (0° declination), giving roughly equal day and night globally. The March equinox marks spring in the Northern Hemisphere; the September equinox marks autumn. Equinox dates are ideal for calibrating solar declination and understanding Earth's axial tilt.
