Actually, Pi day is next year on March 14th, 2015. It may also work today if you take into account only the first 2 digits after the decimal point, but it kind of defeats the purpose.

π is 3.1415926535, no mention of 20. And altho Americans use 3/14/2015, Brits use 14/3/2015 and Asians use 2015/3/14.

Best to say Pi day is every March 14th, from 15:00 to 16:00.

> from 15:00 to 16:00

That seems more like "Pi hour".
