According to the Portuguese Constitution, an election must be called between 14 September and 14 October of the year that the legislature ends. The election is called by the President of Portugal but is not called at the request of the Prime Minister; however, the President must listen to all of the parties represented in Parliament and the election day must be announced at least 60 days before the election.[19] If an election is called during an ongoing legislature (dissolution of parliament) it must be held within 55 days.
