Origins and Significance

Inception: International Astronomy Day was initiated in 1973 by Doug Berger, the president of the Astronomical Association of Northern California. His vision was simple: set up telescopes in busy urban locations so that passersby could enjoy views of the heavens.
Twice a Year: This celestial event occurs twice a year, around the time of the first-quarter moon in both spring and fall. The first celebration of the year takes place on the first Saturday in May.
