Astronomy Day is a day for the interaction between the general public and astronomy community: enthusiasts, groups, and professionals.
The first commemoration was in 1973 by the Astronomical Association of Northern California. The date is to fall on the Saturday at or close to the first quarter Moon (it is also picured in the logo below). Therefore, the date changes every year. 2014's date is May 10, 2014, but 2013's was April 20, 2013. Snce 2007, another Astronomy Day was scheduled to fall on or close to the close of the first quarter Moon. The date for 2014 is October 4, 2014.
At least this page is early rather than late for both 2014 dates!
