The tenure of the President of the United Nations (UN) Security Council is one month. The presidency of the UN Security Council rotates among the 15 members of the Council on a monthly basis, according to the English alphabetical order of their country names. Each member state takes its turn to assume the presidency, which means that each country holds the position for one month throughout the year. During its presidency, the country in charge of the UN Security Council sets the agenda, presides over meetings, and represents the Council in its interactions with other parts of the UN and the wider world. After one month, the presidency is then transferred to the next country in the alphabetical order of member states' names.
