The main part of the festival (the concerts on the stage) takes begins at 21:00 and ends after midnight.
Since 2004, the organizers have opted for continuity, so the permanent festival hosts are Gabriel Cotabiță and Sorana Belciu.
After a year's break, Callatis Club returned to Romanian Television in 2008, presented by Leonard Miron.
In 2006, singer Cream started an argument with host Gabriel Cotabiță because she was on the festival's program but did not actually appear on stage.
Maria Dragomiroiu, Mihai Trăistariu, Simplu and Morandi have publicly expressed their disgust regarding the fact that they performed live on stage but their show was not aired on TV due to a mid-show commercial break.
