What is International Dark Sky Week?

International Dark Sky Week is a worldwide event hosted by the International Dark-Sky Association to celebrate the night and bring attention to the problems caused by light pollution. Each year, International Dark Sky Week is held in April during the week of the new Moon, when the sky is darkest and the stars most visible. This year’s celebrations begin on Sunday, April 19th and runs through Sunday, April 26th, 2020.
