The 23rd November is National Fibonacci day!

I love numbers. 1 – 90 are my favourite! Another famous guy that liked numbers is Leonardo of Pisa – or Leonardo Fibonacci. The 23rd November is a national day of recognition created in his honour.

Fibonacci was born around 1170 in Italy and lived until the 1240s. He is credited with leading Europe to switch from Roman numerals (I, II, III, IV, V etc.) to the digits we use today.

He also publicised the Fibonacci code which was used to explain the solution to the following riddle:

A newly-born pair of rabbits, one male, one female, are put in a field. Rabbits are able to mate at the age of one month so that at the end of its second month a female can produce another pair of rabbits. Suppose that our rabbits never die and that the female always produces one new pair (one male, one female) every month from the second month on. How many pairs will there be in one year?

In the Fibonacci sequence of numbers – which was used to get to the number 144 and answer the riddle – each number is the sum of the previous two numbers. Let’s just park our thoughts about rabbit incest and look at the code for a minute!


It works like this:

1 + 1 = 2

1+ 2 = 3

2 + 3 = 5

And so on…

Can you guess why 23rd November is classed as National Fibonacci Day?

Write it down in numbers in the American way – with the month first, then the day.


You get 11/23 – 1123 – 1,1,2,3 – A Fibonacci date!

Every day’s a school day, roomies! Now go play bingo to reward your learning!
