International Day of Multilateralism
On April 24 2019, the first official International Day of Multilateralism and Diplomacy for Peace will be celebrated and the General Assembly will convene a one-day high-level plenary meeting 
to commemorate and promote the day.
The International Day was officially approved on 12 December, 2018 through resolution A/RES/73/127. 24 April of every year is designated as the day for the international observance.
Preserving the values of multilateralism and international cooperation, which underpin the UN Charter and the 2030 Agenda for Sustainable Development, is fundamental to promote and support the three pillars of the UN – peace and security, development and human rights.
