“Day of Planetaria”, that has been held in different European countries yearly since 1995, is an important opportunity for involving the international community in a collaboration that aims to promote knowledge of planetaria to the public. During this Day planetaria organise shows, lessons, projections, exhibitions and public sky viewing that are low cost or free to the public.

PlanIt is inviting all planetaria, not only the European ones, to take part and support the “Day.” This initiative provides a good chance for diffusing the knowledge of planetaria to the public at large. It is not necessary to make a big effort in order to be able to join the celebration. Planetaria can offer their ordinary program, but should point that “March 13th, 2016” is the annual “Day of Planetaria”.
