The official national flag of Nepal is the world's only non rectangle national flag. The flag was adopted, with the formation of a new constitutional government, on December 16, 1962.
The flag is a combination of two pennants. Its red base is the colour of the country's national flower. Red is also the sign of victory in war. The blue border is the colour of peace. Until 1962, the flag's emblems, the sun and the crescent moon, had human like faces. They were removed to make the flag look more modern. The individual pennants had been used for the preceding two centuries and the double pennant since the 19th century. The flag is designed from its original design, which has been in use for more than 2,000 years.
