Woo Hoo!

Today is Pi Day.

Square Root Day is celebrated when the day of the month and the month are the square root of the last two digits of the year.

Square Root Days fall on the same 9 dates every century.

The next Square Root Day is April 4, 2016 (4/4/16).

And this year, it's pi to four places!
Unless you happened to catch it at 9:26 and a bit more:

10 places!

3.14 15 9:26:53.5
 
Oooooh, I like! I'll keep an eye on my watch tonight and yell Happy Pi Day at the appropriate moment.
 
We didn't watch it swing by this morning, and frankly, I'll probably be busy sawing logs at 9:26, 53 and 1/2 seconds, but in case I'm awake then, call me.
 
I bought two mini pies this afternoon, so we can have a nity-nite snack of pie and ice cream at precisely 9:26 and 54.5 seconds this evening.
 
Next year will be 'Rounded Off Pi Day'.

3.1415927 rounded off is 3.1416.
 
As we write our dates differently in the UK, I generally celebrate fractional Pi day on july 22nd (22/7) marginally closer than the 3 significant figure decimal version.
At least we get our square route days the same on both sides of the pond. :)
