Fibonacci Day is celebrated each year on the 23rd of November. The day aims to honor Leonardo Bonacci, the most influential mathematician of the Middle Ages. Just how influential was Leonardo Bonacci?

Bonacci is credited with creating the Fibonacci sequence, a mathematical counting pattern where every number is the sum of the previous two. Today, this sequence is used by computers to process and store data. It is even used in architecture and trading stocks and is also present in DNA patterns. That’s one of the reasons why science and math classes refer to the Fibonacci sequence as nature’s universal rule or nature’s secret code. The November 23rd date even corresponds with the first numbers of the Fibonacci sequence – 1 1 2 3.

How To Celebrate Fibonacci Day

During Fibonacci Day, science and math classes worldwide hold various fun activities using the Fibonacci sequence. You can join in on the fun by learning more about Leonardo Bonacci and other well-known mathematicians like Newton and Archimedes. You could also mark the day by looking for items in nature or your home that contain the sequence. Some people even bake Fibonacci spiral cookies, creating the perfect dessert for upcoming holidays. Be part of all the math fun during this year’s #FibonacciDay.
