At its first meeting on 17 January 1946, the UNSC adopted provisional rule 18 and established the following method of selecting the president: the presidency rotates monthly among the fifteen members of the Security Council. The rotation takes place in alphabetical order of the member states' official names in English. As such, Australia was the first nation to hold the presidency. Such rotation makes the presidency unique among all United Nations organs. Terms began and ended on the 17 of every month until a suggestion by Australia in December 1946 to change led to the term being extended so the presidency would rotate on the first of every month. The president is the only non-elected head of a United Nations organization.
