Spring Equinox - Sunset

Griffith Observatory marks the start of spring in the northern hemisphere with a live presentation (weather permitting) focused on the Sun as it sets on the western horizon. Inscribed lines in the West Terrace show exactly where the Sun will set on the equinox. Observatory staff will discuss how the position of the setting Sun changes with the seasons. Learn more about the seasons here.


Spring begins in Earth’s northern hemisphere at 8:06 p.m. PDT, March 19. Autumn begins in the southern hemisphere at the same time. The March/vernal equinox is the moment when the Sun crosses the celestial equator (the projection of Earth’s equator into space) from south to north.

What Is Spring?

From the spring equinox until the start of summer – the summer solstice in June – days will get longer, and the noon elevation of the Sun will increase. This happens because the Earth’s axis is tilted 23½ degrees to its orbit. Day and night are of equal length today.
