Luxembourg's government has made significant changes to the country's national day celebrations. A few months ago, prime minister Xavier Bettel announced that changes were to be made to make the the national day more "civil" (though I believe he used the wrong word as civil would probably mean more non-military when he actually meant non-religious a.k.a. secular).
In order to achieve that, a new ceremony at the Grand Théâtre will be hosted in the morning instead of the traditional Te Deum. The ceremony will include speeches by the Prime Minister and the President of the Chamber of Deputies as well as the award of decoration to outstanding citizens. This new ceremony will be followed by the traditional military parade. The Te Deum has been postponed to the evening hours according to Bettel's statement. As the gala dinner for foreign dignitaries usually takes place in the actual evening hours, I guess that the late afternoon is meant. No word yet on which events will be attended by the Grand Ducal Family.
