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.
United States presidential inauguration
The inauguration of the President of the United States is a ceremony to mark the commencement of a new four-year term of the President of the United States. This ceremony takes place for each new presidential term, even if the president is continuing in office for a second term. Since 1937, it has taken place on January 20, which is to days after the November presidential election (on the first Tuesday after the first Monday in November). The term of a president commences at noon ("EST" – Eastern Standard Time) on that day, when the Chief Justice of the United States administers the oath of office to the president. However, when January 20 falls on a Sunday, the chief justice administers the oath to the president on that day privately and then again in a public ceremony the next day, on Monday, January 21. The most recent presidential inauguration ceremony was the swearing in of Donald Trump to a four-year term of office on Friday, January 20, 2017.
