The term of office for a temporary member of the UN Security Council is 2 years.

Non-permanent members of the United Nations Security Council are elected for a term of two years. These members are elected by the United Nations General Assembly, and five of them are elected each year. The rotation ensures that there is a turnover of membership, bringing in new countries to contribute to the Security Council's work and decision-making processes. This system is designed to provide a degree of continuity while allowing for diverse representation from various regions of the world.
