No, not at all. To me it just sounds like you wish to learn more, in this case about another culture and language. And that is always a good thing.
The flag days?
The birthdays of all adult members of the DRF are official flag days.
On flag days all public institutions, buildings and so must fly Dannebrog in the honor of the DRF member who has a birthday.
DRF members under the age of eighteen are not of legal age and as such they cannot act as regent (actually Rigsforstander as only the Crown Prince can be Regent), so no flags are flying in their honor.
There are of course other flag days through out the year.
Ordinary citizens and private businesses are not required to fly Dannebrog on a flag day. If they do, the legislation regarding flying the flag applies.
That legislation is pretty detailed and pretty strict!
Examples:
Dannebrog must
not fly before sun up, or 06.00 in the morning. And it
must be lowered no later than 18.00 or when the sun goes down, whatever comes first.
No flag, not even that of other nations is allowed to fly higher than Dannebrog. - With the exceptions of embassies, which tecnically speaking are located on foreign soil.
A discarded Dannebrog
must be burned on a clean fire. Basically, you fold the flag and place it on a fire, in say the garden.
Failing to do any of the above is a breach of the law.
