Happy Fibonacci Day

It is the day of the year that follows the beginning of the Fibonacci number sequence. 1, 1, 2, 3, and so on. Each subsequent number is the total of the two previous.

Though it originally appeared in Indian mathematics, in Sanskrit, Leonardo of Pisa (known  as Fibonacci) wrote about it in his book Liber Abaci in 1202.

The graphic above shows the sequence. It is used in computer programs and has many other applications.

But the one thing that draws me to Fibonacci is the way you can find it in nature. You can see the sequence in everything from flower petals to fruits and vegetables and my favorite, the shell of the Nautilus.

I usually stink at math but in this case I find it to be quite beautiful. Poetic, even.

If you want to learn more about Fibonacci numbers and their applications here is a great website that explains it all.

I hope you enjoy your Fibonacci Day!


  1. I will now that I know about it. nautilus shells are one of my favorite as well, especially as a measure of progress.

    1. Aren't they beautiful. And yes, they signify progress and growth. Thank you so much for your lovely comment. xoxo

  2. Granted, that doesn’t work outside of the United States, where the convention is to put the day first (23-11).

    1. That is so true, Kim. I am sorry that I didn't address that in my post. I appreciate you reading and leaving a comment. Thank you!
