President of Argentina
Under the 1994 constitutional amendment, the President serves for four years, with a possibility of immediate reelection for one more term. However, unlike the President of the United States, in Argentina, a person may be reelected again after serving for two terms and staying out of office for the following term. So after serving for two consecutive periods, the president is not allowed to run for a third consecutive one, but may return for the two following elections and so on. There is no limit for a person to be a candidate if he or she does not win the elections.
President of the Continental Congress
The length of a presidential term was ultimately codified by Article Nine of the Articles of Confederation, which authorized Congress "to appoint one of their number to preside; provided that no person be allowed to serve in the office of president more than one year in any term of three years". When the Articles went into effect in March 1781, however, the Continental Congress did not hold an election for a new president under the new constitution. Instead, Samuel Huntington continued serving a term that had already exceeded the new Term limit. The first president to serve the specified one-year term was John Hanson (November 5, 1781 to November 4, 1782).
