e-Day: Fun Mathematical Days you Need to Know About

Hello All, I came with some mathematics days which you can celebrate if you are a math lover. I already published some of the articles on this topic and you guys like it very much. So without further ado I am going to tell you the most existing way to celebrate mathematics with your friends and colleague.  


The number e in mathematics is considered very important and that’s the reason why we celebrate e-Day. It is also known as the Euler’s number. E is the mathematical constant with the value of 2.7182818.

Euler’s Number

Leonhard Euler was a Swiss Mathematician and Euler’s Number was referred to after him which is also called the mathematical constant.

He said that e is an irrational number that defines the idea that all the frequently growing systems are a go upward version of a common rate.

It is mostly used in exponential growth, complex numbers, and logarithms, Euler also stated how it is an equally important number in mathematics as so are 0, 1, and Pi (π).

When is e-Day celebrated?

E-Day is celebrated on February 7 in the countries where the date is derived from the month/date format with the value of e which is 2.71 and in other countries that follow the date/month format celebrate on 27 January by taking the first three-digit of the value which is 2.71 as the date 27/1. 

How can you celebrate e-Day?

e-Day can be celebrated by learning more about Euler’s Number and its importance, and its occurrence in mathematics and science. 

You can also prepare food that starts from the letter ‘e’s like eggs, egg whites, eclairs, eggplant, and even eggnog for breakfast, etc. 

e-Day is also sometimes called Napier’s Number because John Napier was the man who created logarithms so in his honor it’s called Napier’s Number as well. Let us know how you are going to celebrate the day, Happy e-Day!

Odd Day

Odd Day rules are quite simple! Be safe, be odd, and have lots of fun. Basically, an odd day is a day that singles out all those odd and wacky numbers together which we have in our calendar.

This day doesn’t occur every year or doesn’t have a particular date; it’s celebrated when three consecutive odd numbers make up a date. Like the last time, it was an odd day on 5/7/09 (5th July 2009) and the next was on 7/9/11 (7th September 2011) this type of thing happens only twice a century. 

So, in this century you have lost the chance of celebrating an odd day if you haven’t celebrated it ever!
