The theme for the 2022 IDM by is “Mathematics Unites”.The theme was proposed by Yuliya Nesterova, a graduate student from the University of Ottawa in Canada.


On 26th November 2019, The executive council of the United Nations Educational, Scientific and Cultural Organization(UNESCO) at its 205th session, adopted a resolution (40C/ Resolution 30) and proclaimed the 14th March of every year as the “International Day of Mathematics”.
