You’ll notice many Danish flags (Dannebrog) flying around Denmark, particularly in homes around the countryside. Flying the Dannebrog, the striking red and white national flag, is an important symbol of pride. Flags on public buildings fly at half-mast on national days of mourning or remembrance. However, the Danish flag is also used in a celebratory manner which is why you might see the flag as decorations at birthdays and on Christmas trees.
