The International Day of Mathematics


The logo is temporary.
A competition to submit bids for the logo of the International Day of Mathematics was started, see the IMU AO Circular Letter 19/2018.

Project IDM, led by IMU, is to have UNESCO proclaim
March 14
as the International Day of Mathematics (IDM).

The project was adopted by the Executive Board of UNESCO at its 205th session in October 2018. It is on the agenda of the 40th session of the General Conference of UNESCO in November 2019. If adopted by the General Conference, the first official celebration will be on March 14, 2020.

A list of all international days endorsed by UNESCO can be found here.

Each year all countries will be invited to celebrate the IDM with mathematics activities in schools and with the general public, under a (non mandatory) theme. Announcements of activities worldwide will be posted on the IDM website.

A call was launched to host the website of the International Day of Mathematics, see the IMU AO Circular Letter 20/2018.

To emphasize the importance of mathematics and mathematical education as a tool for the achievement of the Sustainable Development Goals of the 2030 Agenda (SDG1-17) of the United Nations, Open Source material for curriculum enrichment and activities for the public will be made available.


March 14, often written 3/14, is already celebrated in many countries as Pi Day, since
Π=3.141 592 653 589 793 238 462 643 383 279…
Moreover, the date is convenient for all countries around the world.


The major goals of an International Day of Mathematics, with expected benefits for students, for teachers, for women and girls and for society at large are to:

1.    Improve understanding among the general public, decision makers and in schools, of the importance of mathematics in education;
2.    Contribute to capacity building in mathematical and scientific education, with special focus on girls and children from developing countries (SDG4);
3.    Achieve gender equality and empower women and girls in mathematics (SDG5);
4.     Improve understanding among the general public, with decision makers and in schools of the importance of mathematics as a tool for developments which lead to more prosperous economy circumstances (SDG9);
5.    Emphasize the importance of basic research in mathematical sciences as the seed to breakthroughs in technology and the management of society (SDG8);
6.    Highlight the role of mathematics in the organization of modern society, including economic, financial, health and transport systems, telecommunications in the quest for human well-being, etc. (SDG3);
7.    Raise awareness of the role of mathematics in fighting disasters, epidemics, emerging diseases, invasive species (SDG11);
8.    Highlight the role of mathematics in moving to a circular economy of sustainability compatible with preservation of biodiversity (SDG14 and 15);
9.    Equip the general public and young people with tools for understanding the planetary challenges and the capacity to respond as knowledgeable citizens;
10.    Increase international networking and collaborations in public awareness of mathematics;
11.    Increase the access to information, providing a simple way to give citizens a choice in all aspects of their daily life.


Project IDM is supported by the international and regional organizations:



The website will be designed to allow mirror pages in different languages and the Open Source material related to the theme of the year will be offered in several languages.

Support in many countries:

Organizations in the following countries expressed their support to celebrate the IDM on March 14: Algeria, Argentina, Australia, Austria, Bangladesh, Belgium, Benin, Botswana, Brazil, Bulgaria, Burkina Faso, Cameroon, Canada, Chile, China, Czech Republic, Egypt, Ethiopia, Finland, France, Gabon, Germany, Ghana, Iceland, India, Indonesia, Iran, Israel, Italy, Ivory Coast, Japan, Kenya, Madagascar, Malawi, Malaysia, Mexico, Morocco, Nepal, Netherlands, New Zealand, Niger, Nigeria, Norway, Papua New Guinea, Philippines, Poland, Portugal, Russia, Rwanda, Senegal, South Africa, Spain, Sudan, Sweden, Switzerland, Tanzania, Tunisia, Turkey, Uganda, United Kingdom, Uruguay, USA, Vietnam, Zimbabwe.

The African Mathematical Union (AMU)’s current priority is to exhibit the relevant role of Mathematics in addressing important challenges in Africa, and the celebration of an International Day of Mathematics (IDM) is a part of it. So, the AMU supports the IDM project and will spare no effort to put Africa in the spotlight with celebrations all over the continent., Prof. Nouzha El Yacoubi, President of the African Mathematical Union

In my opinion, having an International Day of Mathematics is long overdue, I know that mathematics makes our lives easier because there is mathematics in everything.  Prof. Adewale Solarin, Past-President of African Mathematical Union.
‘'The suggestion to have March 14th as the International Day of Mathematics was warmly received in Botswana through the Mathematical Association of Botswana. Students, mathematicians and mathematics educators  in Botswana are already looking forward to 14th March 2019, on which they will be engaged in, among others, mathematics quizzes, mathematical games, debates and public lectures.’’ Prof. Mmoloki Lekhutille, Vice-President of African Mathematical Union, Vice-president of the Mathematical Association of Botswana

« L'institution de cette Journée Internationale est très importante à mes yeux car elle permettra de mieux faire connaître les mathématiques par les citoyens du monde entier et de les faire aimer car les mathématiques sont souvent considérées en Afrique et ailleurs comme étant réservées à une "élite cultivée". Nous mêmes, à la Société Mathématique de Côte d'Ivoire (SMCI), nous organisons régulièrement tous les deux ans les "Journées Mathématiques de Côte d'Ivoire" (JMCI) et ceci depuis les années 80. Ces Journées ont pour objectifs de sensibiliser les populations ivoiriennes à la présence des mathématiques dans toutes les activités humaines, de démystifier notre discipline bref, de montrer que les mathématiques, "ça sert à quelque chose". Notre association (la SMCI) soutient donc fermement votre noble initiative et nous souhaitons collaborer avec vous pour co-organiser des manifestations scientifiques en Côte d'Ivoire. » Prof. Saliou Touré, Président de la Société Mathématique de Côte d'Ivoire
