Today is Luxembourg's National Day and both RTL and Wort are streaming the official celebrations live. RTL's live coverage of the day starts at 10am. The Te Deum is expected to commence at 10:30 and ends at about 11:15. The subsequent military parade will start at 12:00 (the broadcast at 11:40) and will also be shown live by RTL. Their coverage of the day's activities ends at 1pm. I expect Wort to have a similar schedule.
In case you are not able to watch it but would like to know what goes on anyway, I will live-tweeting the event on Twitter (@SydneyLux). You can also ask questions and such which I will try to answer to the best of my knowledge. Of course we will also be covering the celebrations right here on the blog. As RTL usually uploads the videos afterwards, you won't miss anything if you can't watch it live.
