While planning a trip, I was looking through a list of public holidays for Romania on wikipedia.
I'm interested to learn about National Anthem Day ("Deșteaptă-te, române!").
According to the article, it is not an official public holiday, but it is recognized as an annual observance. What does this mean? What do people on National Anthem Day? Is there anything that a visitor to Romania should be aware of with regards to National Anthem Day?
