International Dark Sky Week 2021: Save the Date

International Dark Sky Week 2021 Dates

International Dark Sky Week 2021 is rapidly approaching! This year, we invite everyone to discover the night during the week of April 5-12

Every year, the International Dark-Sky Association hosts International Dark Sky Week (IDSW) to raise awareness about light pollution’s many negative effects. It is always held when the sky is darkest and the stars most visible. This annual event was created in 2003 by a then high-school student, Jennifer Barlow. Since then, International Dark Sky Week has grown to become a worldwide event and a key component of Global Astronomy Month. During the week, dark sky defenders worldwide connect over a shared goal to protect the night. 

Everyone is invited to join in International Dark Sky Week 2021! Whether you’re an International Dark Sky Place, chapter, delegate, supporter, or a casual follower there will be ways to engage and participate.
