The General Coördinator of the Eurovision Song Contest 2004 and the Director General of TRT Ankara Radio, Bülent Osma, said that the venue for the Eurovision Song Contest 2004 should be available between 15th of April and 15th of May next year.
Now it is most likely that the contest will take place at May 8th, because May 15th is the last day of this period. As some time is needed to move everything out again after the contest, it's not very likely that May 15th will be chosen as date. May 1st is also not very likely, because the time for building up and rehearsals will be too short.
Osma added that Istanbul Lütfi Kırdar Convention & Exhibition Center is definitely available for these dates.
