Date Sequence

Fibonacci in Nature

One of the beauties of the Fibonacci sequence is that the series is evident all over the natural world. Petal arrangements in flowers, the ordering of leaves in plants, the shell of the nautilus, the DNA molecule and even hurricanes show patterns that correspond to the sequence.

How to Celebrate?

Start the day by learning more about the Fibonacci sequence and its theoretical and practical uses.

A number of fruits and vegetables, like pineapples, romanesco (a cross between broccoli and cauliflower) display the Fibonacci series - incorporate them in your meals to celebrate this mathematical holiday.

Have children in your life? Introduce them to the elegance of math and the importance of learning it to use in real life.

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).

Did You Know…

…that the ratio of two successive numbers in the Fibonacci sequence is very close to the Golden Ratio? The Golden Ratio is approximately equal to 1.6. Objects whose length and breadth exhibit the Golden Ratio are thought to be the most pleasing to the eye.
