Interesting! But I think next year will be the big one.
According to wikipedia :-In the year 2015, Pi Day will have special significance on 3/14/15 at 9:26:53 a.m. and p.m., with the date and time representing the first 10 digits of Pi.
It is the wrong date format for me in the uk but still interesting enough to notice.
And for those that missed it, there is always “Pi Approximation Day” (22nd July) in uk format
