About International Delegate's Day

International Delegate’s Day is observed on 25 April. The United Nations day recognizes the role of delegates and Member State representatives in multilateral diplomacy and in the work of the United Nations.

The date connects present-day diplomacy with the opening of the 1945 San Francisco Conference that produced the Charter of the United Nations.

Why International Delegate's Day matters

Delegates negotiate texts, represent national positions, build coalitions and participate in the collective decision-making through which intergovernmental organizations operate.

The observance is therefore an opportunity to explain multilateral diplomacy as a process of representation, negotiation, compromise, procedure and accountability rather than as ceremonial attendance alone.

History of International Delegate's Day

On 25 April 1945, delegates from fifty countries met in San Francisco for the opening of the United Nations Conference on International Organization. The Conference ultimately produced the UN Charter.

At the initiative of Belarus, the General Assembly adopted resolution A/RES/73/286 on 2 April 2019 and proclaimed 25 April as International Delegate’s Day.

United Nations in Belarus material identifies 25 April 2020 as the first International Delegate’s Day.
