# The Approximately Four Pi Days Of Pi-Day: Pi Day 1

In honour of Pi-Day (which we all know arrives March 14th, each and every year), I shall be presenting to you dear reader the Approximately Four Pi Days Of Pi-Day; a Pi-Day-carol that I wrote after consultation with various nerds I know.  And since Pi is ubiquitous, I try to include as many nerdy things related to Pi as I can in this one all-encompassing carol.  You are welcome.

Before presenting the uber-awesome carol that is the Approximately Four Pi Days Of Pi-Day, it should be noted that 1 Pi day is approximately 3.14 regular 24 hour days. Hence, four Pi days are a little more than 12 regular days. Do you see where this is going? You can probably imagine the following items put to the tune of the Christmas carol The Twelve Days of Christmas. Of course, I’m betting that you’ll find this far more entertaining than the Christmas carol. Or maybe that’s just me.

The carol will be doled out over the course of the next 4 Pi days. That is, you’ll get the first 3 regular days today, with the remaining 9 regular days on March 6, March 9, and March 12. So, for those keeping track, we have

1. Pi day #1, released March 3 at 3:14pm, and spanning March 3-5,
2. Pi day #2, released March 6 at 3:14pm, and spanning March 6-8,
3. Pi day #3, released March 9 at 3:14pm, and spanning March 9-11, and
4. Pi day #4, released March 12 at 3:14pm, and spanning March 12-14.

Did you notice the time when the carol will be released?  It’s Pi-Time.  This means that you should have a slice of pie on hand to celebrate properly.  Anyway, given that Pi-Day is officially celebrated on March 14, you will be able to practice the song in its entirety in time for the mathiest of all math days.

Regardless of what you know about Pi, where you may see it in your day-to-day life, or how many digits you have memorized, Pi-Day should be loved and celebrated by all.  And with that, I present to you dear reader, the first Pi Day of Pi-Day.  Enjoy!

• On the first $\frac{1}{3}$ Pi day of Pi-Day, Euler gave to me, $|e^{i\pi}|$1.
• On the second $\frac{1}{3}$ Pi day of Pi-Day, a Statistician gave to me, a bivariate Gaussian distribution2.
• On the first full Pi day of Pi-Day, a Physicist gave to me, three lectures on quantum physics at the P.I.3.

In a related story, here is a video that describes the 12 days of Christmath. It’s epic in its awesomeness. I love it long time. Long. Time.

1. I think the person in this video is your soul mate…

2. Haha! 5 = the number I like to do high. Brutes.
