The president submits a written resignation to the Speaker of the National Assembly and informs the public at the same time. The mandate ends on the day the resignation is submitted. Nothing has to be noted, confirmed or accepted, and no one has to wait.
The Speaker of the National Assembly then takes over the duties of the president and calls the election. That is the whole mechanism, and it is why the entire calendar in this tool hangs on a single date.
The procedure is started in the National Assembly on the proposal of at least one third of MPs. The Constitutional Court has 45 days to decide whether the constitution was violated. Removal is then adopted by at least two thirds of all MPs.
Because of the 45 days at the Constitutional Court, and because it needs a two-thirds majority, this route has never been used.
How the dates are counted. In calendar days, exactly as in the law. Deadlines do not move when they fall on a weekend or a holiday, because the law does not provide for that. For deadlines that run backwards from the voting day, the tool shows the last full day on which the act can still be done, so where the law says "no later than 20 days before the day of voting" the tool shows the 21st day.
What the tool does not do. It does not suggest a date and it does not predict one. It shows what the law allows and what it rules out. The full list of deadlines for a called election is in the election calendar; this tool carries only the ones that decide the shape of the window.

The duty to call and hold a presidential election: the legal basis
The Law on the President of the Republic specifies that the resignation is in writing and that the President's mandate ends when it arrives at the National Assembly (Article 14 of the Law).
The Law on the Election of the President of the Republic provides: that if the President's mandate ends before the expiry of the term for which they were elected, the election is called so that voting is held no later than three months from the day the President's mandate ends; that no fewer than 30 and no more than 60 days may pass between the day the election is called and the day of voting; that the decision calling the election sets the day of voting; and that a non-working day is set as the day of voting (Articles 10 and 11 of the Law).
Deadlines for calling and holding the presidential election in the present circumstances
In line with the provisions of the Constitution and the law, under which the presidential election must be held within three months of the President's resignation, the latest date for calling the election would be 27 November 2026 - which would mean an election campaign of 30 days.
The election would be held on 1 November 2026 at the earliest and on 27 December 2026 at the latest (bearing in mind, besides the statutory deadlines, that the day of voting must be a non-working day).
The term "holding the election", used by the Constitution and the law, means the election day on which voting in the presidential election is carried out, and which may at the same time be only the first round of that election.
The Rules of Procedure of the National Assembly: a duty to call the election immediately upon the President's resignation?
It follows from the provisions of the Law on the Election of the President of the Republic that the Speaker of the National Assembly has the power to call the election within one month of Aleksandar Vučić's resignation from the office of President of the Republic - between the day the resignation arrives and the day from which, 30 days later, the election will be held. The Rules of Procedure of the National Assembly, however, expressly provide that the Speaker, upon receiving notification of the resignation, informs the MPs of it and at the same time calls the election for President of the Republic.
CRTA's reading: when must the presidential election be called?
It should also be borne in mind that the Rules of Procedure of the National Assembly govern the organisation and work of the National Assembly and the manner in which MPs exercise their rights and duties (see Article 1 of the Rules of Procedure), which means that the Rules of Procedure regulate the work of parliament in an operational sense and are not a piece of legislation in the field of electoral law in the Republic of Serbia.
From the above, the following can be concluded:
