International Astronomy Day is celebrated every year on ________ date ?

International Astronomy Day is celebrated twice a year — one in autumn and another in spring. The Astronomy Day 2020 is celebrated on May 2. The world will celebrate the next Astronomy Day on September 26. On this day, museums, societies, astronomical institutions and planetariums organise seminars, workshops and other fun-filled activities to spread awareness about the world of astronomy. According to starwalk space, in 1973, Doug Berger, president of the Astronomical Association of Northern California, had organised the celebration of first Astronomy Day. The idea behind observing the day is to create awareness and educate people about the beautiful universe.
