Le jour de la nuit - the day of the night

This Saturday is "Le jour de la nuit" across the whole of France. The idea is to switch off all municipal lights so as to be able to observe the night sky, the stars and enjoy the biodiversity of darkness. It really sounds like fun. Ferney is going to take part, though not Geneva as the idea doesn't seem to have spread to Switzerland yet.
There are several fun things taking place including a night time walk to look at excessive private lighting and the problems of light pollution. The local astronomy club is setting up telescopes in the garden of the Maison St Pierre next door to where we live so that we can all look at the winter night sky. Find out more here.
Meanwhile I just love the play on words of "le jour de la nuit" which means both the day of the night and also the daylight of the night. In spiritual terms I also love the idea of the night and the darkness also being holy. I think Sautrday night might be quite fun - and also the big switch off will really help to reduce carbon emissions - maybe we should be having more days of the night. That night is also the night we all get to sleep an hour extra as the clocks go back, so the switch off will last an hour longer too!
