March 14 is International Mathematics Day.

 A worldwide event is held in honour of the International Day of Mathematics (IDM). Every year on March 14, activities are held at schools, museums, libraries, and other locations that are open to the public as well as students from all nations. 

At its 205th meeting, the Executive Council of UNESCO declared March 14 to be the International Day of Mathematics. In November 2019, it was approved by the UNESCO General Conference's 40th session. On March 14, 2020, the IDM held its official opening ceremony. 2020's theme was "Mathematics is Everywhere." 

There are various departments in maths. Such as algebra, trigonometry, and factors etc. So, there are also sub-departments in factors such as pair factors and prime factors of a number such as 47 etc.

Here is a list of all the things that happened that fit inside the parameters of this theme. The focus in 2021 was on mathematics for a better world. Here is a chronology of what happened. For 2022, the topic was Mathematics Unites.

A new topic will be introduced each year to add flavour to the celebration, encourage innovation, and highlight the connections between mathematics and a variety of fields, concepts, and ideas.

MATHEMATICS DAY HISTORY

The renowned mathematician Srinivasa Ramanujan, whose achievements have had an impact on many people throughout the nation and the world, is the driving force behind the creation of Mathematics Day in India. Iyengar Brahmins raised Ramanujan at Erode, Tamil Nadu, where he was born in 1887. He had little formal schooling when he was 12, but he was an expert in trigonometry and created a number of his own theorems.

After completing secondary school in 1904, Ramanujan qualified for a scholarship to attend the Government Arts College, Kumbakonam, but was unable to win it because of his lacklustre performance in other areas. When he was 14 years old, Ramanujan ran away from home and enrolled at Pachaiyappa's College in Madras. Ramanujan, like many other mathematicians, only managed to thrive in mathematics without managing the same in other areas, therefore he was unable to complete with a Fellow of Arts degree. Ramanujan, who was living in extreme poverty, chose to conduct his own independent research in mathematics.

The aspiring mathematician was soon spotted in Chennai's math communities. He was assisted in 1912 by Ramaswamy Iyer, the Indian Mathematical Society's founder, in obtaining a clerk position at the Madras Port Trust. The breakthrough came in 1913 when Cambridge-based GH Hardy invited Ramanujan to London after being impressed by his theorems. Ramanujan had been sending his work to British mathematicians up until that point.

In 1914, Ramanujan arrived in the UK, where Hardy helped him gain admission to Trinity College, Cambridge. Ramanujan was well on his way to success when he was elected to the London Mathematical Society in 1917. In 1918, he also became one of the youngest people to be named a Fellow of the Royal Society.

Ramanujan left for India in 1919 because he struggled to adjust to the food in Britain. His condition continued to worsen, and he passed away in 1920 at the age of 32. But his contributions to mathematics continue to be held in high regard around the world. Mathematicians worked on Ramanujan's unpublished conclusions for years after his death. He left behind three notebooks, each of which contained several pages. The day of Ramanujan's birth, December 22, was so important that former Indian Prime Minister Manmohan Singh proclaimed it as National Mathematics Day in 2012, to be observed nationwide.
