Today is a multitude of celebration. First of all you have Pi Day, 3.14, but you've missed the celebrations, which should have happened at 1.59 this morning. If that's way too geeky for you, then there is White Day. And, incidently, it's everyones favourite (mad) scientist, Albert Einstein's birthday too.
Personally, I'm waiting until next month, to celebrate Black Day. Hmmm noodles.
