March 14th, is written as: 3/14, au 3.14 This decimal is also known as pi. So, I guess on 3/14/15 mathmaticians will be REALLY happy, because the inayofuata part of pi is 15. :)
People have already answered this adequately but I'd just like to add that "Pi Day" only makes sense in the United States.
Citizens of Europe and the UK, for example, write their dates day, month, year, not month, day, mwaka like the Americans. Therefor, to them, today is 14.3.2009 not 3.14.2009.
It's the third mwezi of the mwaka and the 14th. 3.14 Get it?

Well, yes I get it but it makes no sense to me. Like Cinders alisema not everyone writes the date/month/year universally. I'm Australian and here we write 14.3. Just a bit of trivia while I'm already here... Downunder it's already 15.3 au be it 3.15.lol!
