Can you hear it? That’s the sound of the awesomeness approaching.

It starts this Wednesday.

5/8/13

The month, date and year are consecutive terms in the Fibonacci sequence.

It continues on Thursday.

5/9/13

The numbers form an arithmetic sequence.

And then there’s Sunday.

5/12/13

That’s a Pythagorean triple.

Arithmetic sequence dates are a dime a dozen. In fact, there are six of them in 2013 alone. Pythagorean dates and Fibonacci dates are far more rare. There are only eight Pythagorean dates and six Fibonacci dates in the entire 21st century. To have all of them occur within a six-day span is incredible.

**How will you celebrate?**

6.mathmom | May 11, 2013 at 11:24 pmMy son was excited to be taking his AP calc exam on the first of such a list of mathy dates :) My boys have taken on the challenge to present a Mother’s Day breakfast worthy of the Pythagorean date.

7.venneblock | May 12, 2013 at 8:22 pmDo tell, mathmom! What did they make? Right triangle waffles? Pancakes that formed a visual proof of the theorem? I’m dying to know!

8.mathmom | May 12, 2013 at 8:25 pmI do like that pancakes idea! Next time :) I got toast cut into 5-12-13 triangles, 4 of which were combined to form a larger similar triangle, along with fruit cut into appropriately-shaped triangles and eggs arranged into a 5-12-13 triangle on the plate. ;-)
