Astronomy Day 2005 is set for April 16

"Astronomy Day is a grassroots movement designed to share the joy of astronomy with the general population."


"Anyone celebrating the event is welcome to distribute any number of copies of the Sky Calendar with no restrictions, other than that [The Abrams Planetarium at Michigan State University] asks that material not be deleted. Scroll down the page and click on 'Sample Sky Calendar' or 'Sample Sky Map.'"
