Celebrate Fibonacci Day with friends and family! Enjoy the mathematical fun with puzzles, games, and activities to pay homage to the genius of Leonardo Fibonacci.

Introduction

Get excited to celebrate Fibonacci Day on Nov. 23! This day is dedicated to the famous Italian mathematician Leonardo of Pisa, more commonly known as Fibonacci. He was born in 1170 and introduced a sequence of numbers that has been used for centuries by mathematicians all over the world. His work revolutionized mathematics and still serves as an inspiration today. So let's take some time out of our day to honor his great contributions by celebrating this special holiday!
