 Important Days in Mathematics

Pythagorean Day

Pythagorean Day is celebrated around the globe to commemorate the well-known theorem Geometry Pythagoras' Theorem. Pythagoras' formula calculates the date of celebration. The Pythagoras equation states that the sum squares of the base and perpendicular are equal to the courts of the hypotenuse. A year's celebration date falls on the day the sum of squares for the date and month equals the yard for the last two digits.

Example

Pythagorean Day was August 15, 2017, 2017. 

Let's find out how it is calculated.

Date = 15

Month = 8

The last two digits of 2017 = 17

152+82=225+64=289

also, 172=289

So, on August 15, 2017, the sum of squares 15 and 8 equals square 17.

It is how Pythagorean Day is calculated.

July 24, 2025, is the next Pythagorean Day in the Future.

Fibonacci Day

Every year, Fibonacci Day falls on November 23. It is held to honor Leonardo Bonacci (an Italian mathematician who was the most skilled Western Mathematician in the Middle Ages) and is also celebrated. Leonardo Fibonacci and Leonardo Pisa are also common names for him. He introduced Europe to the Hindu- Arabic numeral systems to make it easier to use numbers other than Roman numerals. He created the Fibonacci numbers, one of the most important sequences of numbers. This unique ratio is known as the "Golden Ratio" in mathematics. Surprisingly, the Golden ratio can describe many natural phenomena and financial markets.

Fibonacci Day is celebrated every year on November 23. The date 11/23 was chosen because the numerals in 11/23 make the Fibonacci sequence, i.e., 1, 1, 2, 3.

Pi Day

Pi, the most well-known number and a constant in mathematics, has a value of 3.142. It is observed every year on March 14. November 2019 is also known as the International Day of Mathematics. Because the three digits 3 and 1 make the Pi value's first three numbers, it is observed on 3/14.

E-Day (Eulers Number)

E-day is a celebration of the mathematical constant Euler's Number, also known as Euler's Number. It has a value of 2.718281818. Every year, it is celebrated on February 7. The Euler's Number has the first two digits that determine the date.

Women in Mathematics Day

Every year, May 12 is Women in Mathematics Day. It's a day to recognize women for their accomplishments in mathematics. Events will be held from May 1 through June 15 to celebrate the occasion.

Square Root Day

Square Root Day is the rarest day in mathematics because it can't be celebrated yearly. Surprisingly, it is only nine times per century. It is celebrated on days when the date and month are equal square roots of the last two digits in the year. Ron Gordon, a Redwood City high school teacher, started it on September 9, 1981 (9/9/81).

On April 4, 2016, the last square root day was celebrated (4/4/2016). Next Square Root Day will be May 5, 2025 (5/5/25). 

Let's look at an honest root day to see how it is calculated.

Example

February 2, 2004, (2/2/04).

Day = 2, Month = 2, Year = 04

Day = 2 = 4.

Month = 2 = 4.

The square root of the year 04 equals both month 02 and day 02 of 2/2/04

May 5, 2025 (5/5/25) 5 5 25 25 = 5

June 6, 2036 (6/6/36) 6 6 36 1 = 6

July 7, 2049 (7/7/49) 7 7 49 49 = 7

August 8, 2064 (8/8/64) 8 8 64 64 = 8

September 9, 2081 (9/9/81) 9 9 81 81 = 9

Palindrome Day

Palindrome Day is a day that makes the same pattern as Palindrome. A palindrome can be described as a word or number read in forward or backward directions. Reading in both directions will produce the same word or number.

A day must have the format of mm/dd/yy or just mm/dd/yyyy to qualify as a palindrome. 02/02/2022 was the last day of Palindrome. The 20/03/2023 Palindrome is the next. Let's see below for the next dates of the Palindrome.

Example

March 20, 2023

It can be written in m/dd/yy as 3/20/23

The number sequence for the forward direction (left-to-right) is 32023.

The number sequence for backward is 32023 (right to the left).

It is, therefore, a palindrome since the number 32023 appears to be the same in both directions, making 3/20/23 a palindrome day.
