Today is Fibonacci Day! #fibonacciday

Fibonacci day fun

November 23 is Fibonacci Day, an annual holiday that honors one of the most influential mathematicians of the Middle Ages – Leonardo Bonacci. Todays date corresponds to the first numbers of the Fibonacci sequence – 1 1 2 3. In mathematics, the Fibonacci numbers, commonly denoted Fn, form a sequence, called the Fibonacci sequence, such that each number is the sum of the two preceding ones. Via Timeanddate.com

Also known as Leonardo of Pisa, he is popularly known as Leonardo Fibonacci. Fibonacci is a contraction of filo Bonacci, meaning the son of Bonaccio.

Date Sequence

November 23 is celebrated as Fibonacci day because when the date is written in the mm/dd format (11/23), the digits in the date form a Fibonacci sequence: 1,1,2,3. A Fibonacci sequence is a series of numbers where a number is the sum of the two numbers before it. For example: 1, 1, 2, 3…is a Fibonacci sequence. Here, 2 is the sum of the two numbers before it (1+1). Similarly, 3 is the sum of the two numbers before it (1+2).
