I’m not sure how I missed it, but yesterday was Fibonacci Day. It is on November 23 because the first numbers of the Fibonacci Series are 1, 1, 2, 3. The Fibonacci sequence adds the previous 2 numbers to get the third.

Leonardo of Pisa, sometimes known as Leonardo Fibonacci or just Fibonacci, was an Italian mathematician. He didn’t invent or discover the Fibonacci sequence, but he used it as an example in his book, *Liber Abaci*.

Tiling squares whose sides are consecutive Fibonacci numbers and then drawing a arc connecting opposite corners creates a Fibonacci spiral which approximates the Golden spiral.

Do a little discovering of your own on Fibonacci numbers. They are fascinating.

Why?? is Fibonacci Day not January 12 as 0+1=1+2 is actually the numbers as Leonardo Fibonacci would have wrote them. Just a Idea that flashed on my mind as zeros are very important in any mathematical equation.
