As usual for the last years, the rehearsals for the participants start already almost two weeks before the contest - called Euroweeks.
The rehearsals will be in the order of the Running Order Draw, conducted in March at the Heads of Delegations meeting. This means that the first round of rehearsals - 40 minutes each - will be started by Poland at 10:00 Central European Time (CET) in the Düsseldorf Arena.
The rehearsals are each followed by either a press conference, interviews, photo opportunities or fan meet and greets or a mix of those.
The second round of rehearsals - this time 30 minutes - will begin on Thursday, the 5th of May and will be accompanied by 30 minute press conferences.
The so-called Big 5 countries - Italy, United Kingdom, France, Spain and the Host Country, Germany - will have their first rehearsals on Saturday, the 7th of May.
That is also the day when the traditional Welcome Reception will be held, where all the delegations are greeted officially by the City of Düsseldorf as well as the organisers of this year's contest.
The second round of rehearsals for the Big 5 countries will be held on the next day, but their second press conferences will be held a little later - on the following Friday before the Grand Final.
