International Dark Sky Places Calendar 

Find the latest information on events at our International Dark Sky Places on the calendar below. For more information click on the event.

Times displayed on this calendar are based on the USA East Coast time zone (GMT -05:00). To see when the event is happening  in its time zone click on the event then click 'more details.' A new page will open with the time of the event switched to that location's time zone.

For example, on this page an event at Death Valley National Park says it is happening at 10pm, but when you click for "More Details" it says it is happening at 7pm. This is because at Death Valley it will be 7pm when the event happens and on the East Coast of the USA it will be 10pm. So, if you plan to travel to an event please check the location's time by clicking "More Details."
