About International Asteroid Day

International Asteroid Day is one of the international days on the United Nations list. The UN uses these days to draw attention to an issue and to what people around the world are doing about it.

In 2027 it falls on a Wednesday; in 2028 it’s on Friday 30 June, and in 2029 on Saturday 30 June. Also in June 2027: National Ceviche Day (28 Jun), Teachers’ Day (Dominican Republic) (30 Jun) and Armed Forces Day (Guatemala) (30 Jun). From this page you can add it to your calendar, get an email before it, share the countdown, or show it full screen.
