According to the official website Eurovision.tv the next Eurovision Song Contest will be held a week earlier as previously announced.
The new dates for 2014 are:
Semi Final 1: 6th May 2014
Semi Final 2: 8th May
Grand Final: 10th May 2014
The reasons for this might be capacity issues of the venues with other events like concerts, sports-events, etc. Due to the fact that the host city is still unclear and several candidate cities have already withdrawn like Frederica and even the Parken Stadium in Copenhagen, it seems unreal that the capital Copenhagen gets the ESC 2014. This will cause some problems with accommodation for all the delegations, visitors and media representatives.
