International Meditation Day

I was watching some film a while ago, it might have been "What the Bleep do we know about physics" and it mentioned a cool phenomenon in which, if a certain amount of people all meditate at once it is proven that the crime rate will drop a certain percentage. So I had this idea that it would be cool if there was one day or a certain week every year and of course at a certain time or hour in which people throughout the world all meditate at the same time. Funny thing is I dont even really know how to meditate, but anyway imagine millions of people across the world all meditating on a certain day at a certain time. Above and beyond that imagine if they had a class in schools that taught meditation and it was taught at the same time across the world. Kids all meditating at the same time. Anyway, to further this thought. What would be the best time and day or week for this to happen? ie. during a solar eclipse, full moon, certain month or whenever during a specific time during the year? A meditation holiday "Chill DaY".
