Hello everyone, today I’m going to tell you about some mathematical holidays which most people aren’t aware of and those holidays are celebrated in different parts of the world. Fibonacci Day, Sonia Kovalevsky Mathematics Day, Math 2.0 Day, Mole Day are the topics that will be included in the article.

**Fibonacci Day**

### **What is Fibonacci Day?**

Leonardo Bonacci also known as Leonardo Fibonacci who invented the pattern of counting which now impacts math and technology.

In this sequence, the pattern is made up of numbers and it is produced by adding the previous two numbers to get the next number like 1, 1, 2, 3, 5, 8, 13 and it goes on.

When this sequence was discovered it started showing up everywhere, Fibonacci is everywhere in nature as well and is full of Fibonacci patterns and forms.

This sequence of numbers was mostly used in stock trading, computing, design, and architecture.

**How is Fibonacci Day celebrated?**

Fibonacci Day is celebrated on November 23. This date was chosen from the first numbers in the Fibonacci sequence which are 1 1 2 3.

The best way to celebrate this Day is by researching and studying the Fibonacci sequence, and definitely, you are going to enjoy it because the sequence leads to so many mind-blowing discoveries which you won’t even expect.

You can also create the Fibonacci sequence. It isn’t difficult at all. You can start with 0, 1, and keep adding the previous two numbers like 0, 1, 1, 2, 3, 5, 8, 13, 21, and so on. Do tell in the comment box how much longer you go!

**In normal life can you find the Fibonacci sequence?**

Yes, there are a lot of places you can find the sequence even in your house and everywhere nature is filled with uniqueness. It is just the efforts we have to put in.

For example, you can go through giant sunflowers seeds situated in the center, flower petals as most of the flowers contain a lot of petals, etc if you find any other such thing do share in the comment section.

**Sonia Kovalevsky Mathematician Day**

*Who is Sonia Kovalevsky?*

*Who is Sonia Kovalevsky?*

Sonia Kovalevsky born in 1850 was the first Russian woman who received a Doctorate in Mathematics, this day is celebrated in the honor of an amazing 19th-century mathematician.

Her enthusiasm to study in the best university and with a lot of struggles opened doors for other women to enter the universities as well.

*What is Sonia Kovalevsky Mathematician Day?*

Sonia Kovalevsky Mathematician Day doesn’t have a specific date to celebrate. This day is majorly celebrated to encourage women who have interest and potential to pursue mathematics and build their careers in the same.

*How is Sonia Kovalevsky Mathematician Day celebrated?*

This day is celebrated with all the female students who have an interest in Mathematics. As this holiday doesn’t have a fixed date but it usually takes place in the spring season and the celebration events are held in middle schools and high schools for all the women.

## **Maths 2.0 Day**

### **What is Maths 2.0 Day?**

Maths 2.0 Day celebration reminds us of how important mathematics is. Earlier, people used to think that there would be no jobs in mathematics and used to study physics or chemistry or biology.

But now without mathematics life would be very difficult, in schools and colleges students don’t really like math because of its difficult concepts but in normal life, it is not that hard.

On Maths 2.0 Day let’s celebrate by understanding the importance of the subject and teaching other people how they can use math in their daily lives without getting confused.

**History of Maths 2.0 Day**

Maths 2.0 Day celebration was started in the year 2009 most importantly for the blending of technology and mathematics. And to showcase how people have used mathematics in different forms and to involve people and build their interest in math for the future in technology and math itself.

Maths Future Group, wherein this day is a part of this and all inventors, mathematicians, teachers, professors, researchers, etc. are involved and encouraged to teach people, students about math and learning it.

On this day a lot of discussions, sharing of news, technological discoveries, and information are shared.

**When is Maths 2.0 Day celebrated?**

Maths 2.0 Day is celebrated on July 8 every year. It started in 2009 and has been going on since then. This day celebrates math as a subject and to let people know the importance of it, we don’t even know when and where we are using mathematics numerically or geometrically.

**How is Maths 2.0 Day celebrated?**

You can start by encouraging people and letting them know about mathematics, you can also solve some amazing math problems or an equation with your friends and family, and you can also learn new concepts or formulae, there are events conducted by universities, schools, and companies in which you can take part to know more about the day.

You can also challenge it on social media and make people engage in the activity by yourself, you can teach people around you and encourage them about how easy math is and in how many ways it can be used.

We should enjoy every bit of the day, so Happy Maths 2.0 Day!

“Without mathematics, there is nothing we can do. Mathematics is everywhere, everything around us is mathematics, everything around us is numbers.”

**What is Mole Day?**

Mole day, also known as mixing math and chemistry, is a day that celebrates the number which is a basic unit in chemistry used for a measurement called Mole (6.02×1023).

It’s Avogadro’s number. The main focus is to make students start building interest in chemistry by doing various sorts of activities linked with moles and chemistry.

**History of Mole Day**

This day first originated in the 1980s in one of the articles The Science Teacher taking inspiration from the article by a high school teacher, Maurice Oehler who taught chemistry in Prairie du Chien, Wisconsin founded on 15 May 1991 about (NMDF) National Mole Day Foundation.

Every year around 23 October from Saturday to Sunday National Chemistry Week is sponsored by the American Chemical Society this makes Mole Day play an integral part in National Chemistry Week as well.

**When is Mole Day and how is it celebrated?**

Mole Day is an unofficial holiday that is celebrated every year on October 23 by all the chemists, chemistry enthusiasts, and chemistry students between 6:02 am to 6:02 pm.

In the American style of writing 6:02 is 10/23 wondering about the date and timing. It’s derived from the Avogadro number which is (6.02×1023) it derives defining the number of particles, most atoms, and molecules in one particular mole of a substance, it’s one of the seven base SI units.

This day is special to all those who are associated with chemistry and many events and activities are held on this day at different places.

The National Mole Day Foundation has a theme for each year’s celebration, with 2015 being “May the MOLES be with You.” Past punny iterations include “Molar Eclipse,” “Ride the Rollercoaster,” and “Remember the Alamo.”
