The Nepal Flag was officially adopted on December 16,
1962 and it is the only national flag that is not rectangle or square.
The blue border in the National Flag of Nepal symbolizes peace, while red
is the colour of the Rhododendron- Nepal's National flower. The crescent
moon represents the Royal House, while the Sun is the symbol of the Rana
family of Nepal.
Initially the sun and moon in the National flag of Nepal had human faces,
but they were removed when the flag was updated in 1962. The flag is said to
express the hope that Nepal will endure as long as the sun and the moon
exist. The present National Flag of Nepal was adopted on December 16, 1962.
The flag of Nepal is the only national flag which is not rectangular in
shape. It is based upon two separate pennants which belonged to rival
branches of the Rana dynasty, which formerly ruled the country. The two
pennants were first joined in the last century, but it was not adopted as
the official flag until 1962, the year in which the constitutional form of
government was established in Nepal.
