March 14 of each year is Pi Day, founded in 1988 by Larry Shaw and supported by a 2009 resolution in the U.S. House of Representatives. Those of us who use the date format like 3/14 can match up the digits with the first three significant digits of Pi, 3.14. I’m a number geek who enjoys a bit of silly fun with things like this.

Twenty-two significant digits so far. You can take it further if you like. Others certainly have.

It is a good thing I had not invested in party hats, whistles and fireworks, let me tell you! The magical Pi instant had passed by me unbeknownst.
