Happy π Day!

Today "is March 14, or, as it’s written in the U.S., 3/14. That makes it Pi Day, because the mathematical constant π is roughly equal to 3.14. Nerds celebrate this date every year, because, well, we’re nerds. Duh.

But this year’s π Day is special: It’s the year 2015, so the date is 3/14/15, giving us two more decimal places of the famous constant. In fact, if you celebrate it at 9:26:53 today, you get π to nine decimals: 3.141592653. Since the next digit is a 5, you can even round up and celebrate π Day for an extra second. Woohoo!"
