International Astronomy Day

Saturday, May 3, 2025

Astronomy Day was created in 1973 by Doug Berger, then president of the Astronomical Association of Northern California. The unofficial holiday is an attempt to raise the interest of the general public in astronomy by giving them easy access to astronomical instruments such as telescopes.

The holiday also seeks to bridge the knowledge gap by giving the public a chance to interact with astronomers and space scientists.
