Because Astronomy Day is a holiday that is meant to draw attention to all aspects of the study of the stars and planets that hover in the sky, the celebration of Astronomy Day takes place in a variety of venues.  These venues include obvious choices like planetariums and optics shops that specialize in telescope lenses.  Indeed, it is certainly an important part of Astronomy Day to celebrate this holiday in venues and locations that are closely tied to the practice of astronomical observation, because people who pursue the practice of astronomy as either a profession or as a casual hobby are the people who make Astronomy Day happen.  Given this fact, it is little wonder that most Astronomy Day events happen in places that are frequented by members of the Astronomy community.

However, Astronomy Day events are not limited to these kinds of venues where astronomers usually gather.  The venues and locations where Astronomy Day gatherings are held include less obvious choices like shopping malls and busy intersections.  These are places where sidewalk astronomers are sure to get the attention of passersby who may not even have heard of Astronomy Day and the many active astronomy groups that make it possible.  Because Astronomy Day is a holiday that is meant to draw attention to all aspects of the study of the stars and planets that hover in the sky, the celebration of Astronomy Day is meant to attract attention from people who are not already interested in astronomy.  These people would not be likely to attend an event at a planetarium, observatory, or telescope store, so to reach these kinds of people on Astronomy Day astronomers who hold Astronomy Day events need to hold events and meetings in places like malls, public parks, and other areas that are not immediately associated with Astronomy Day and astronomy in general.

Many people spend a lot of time getting everything organized to make Astronomy Day what it is.  Because Astronomy Day and the many events that take place on Astronomy Day don't organize themselves, it is important for people who care about astronomy to take initiative and make events happen.  Although Astronomy Day may sound somewhat whimsical and playful in nature, many people take it very seriously.  A great Astronomy Day event requires weeks and sometimes even months to plan and organize, and there are hundreds of Astronomy Day events that happen all over the world, so the network of people who make Astronomy Day possible is a large and impressive one indeed.

In fact, some people would argue that due to the size and scope of Astronomy Day and the many active astronomy groups that make it possible, Astronomy Day is one of the most subtly pervasive holidays created in the modern age.  Astronomy Day and the events that take place on this unique holiday are truly inspirational, because they show that with a lot of hard work it is quite possible to establish a fun and educational new holiday in the modern age.  Indeed, Astronomy Day is one of the most popular holidays created in recent times, and its popularity is growing every year.
