European nations are hosting various initiatives to promote nighttime awareness and address light pollution.

In France, the 18th edition of ‘Jour de la nuit’ (Day of the Night) involves public lighting shutdowns, stargazing, and educational activities to highlight the impact of artificial light on biodiversity and energy use. While global nocturnal light has increased, France has reported a 33% reduction between 2014 and 2022, though 85% of metropolitan France still faces significant light pollution.

In the Netherlands, the 22nd ‘Night of the Night’ aims to protect nocturnal wildlife and human sleep rhythms by reducing unnecessary lighting. This is accompanied by the debut of the ‘Night of the Castle’ festival, which uses evening programs and light activities to showcase cultural heritage.
