<P> The national flag of Nepal (Nepali: नेपालको झण्डा) is the world's only non-quadrilateral national flag . The flag is a simplified combination of two single pennons (the vexillological word for pennants), known as a double pennon . Its crimson red is the colour of the rhododendron, Nepal's national flower, while the blue border is the colour of peace . Until 1962, the flag's emblems, the sun and the crescent moon, had human faces, but were removed to modernize the flag . </P> <P> The current flag was adopted on 16 December 1962, along with the formation of a new constitutional government . It borrows from the original, traditional design, used throughout the 19th and 20th Centuries, and is a combination of the two individual pennons used for more than 2,000 years . </P> <P> After Prithvi Narayan Shah unified all small principalities of Nepal, the double - pennon flag was adopted . In modern times, the flag's symbolism has evolved to incorporate several meanings . The crimson red indicates the bravery of Nepali people and is the country's national colour and the blue border represents peace and harmony . The colours are often found in Nepalese decoration and works of art . The triangular shape of the pennons originally represented the Himalayas, with their sizing denoting important families - Shahs for the upper, and the Ranas below . Another theory is that the two points represented peace and hard work, using the symbols of the moon and sun respectively . However, the modern and government sanctioned representation is of Hinduism and Buddhism, the main religions of the country . </P> <P> The inclusion of the celestial bodies indicates Nepal's permanence, and the hope that Nepal will enjoy the same longevity as the Sun and the Moon . Additionally, the stylized moon represents the calm demeanour and purity of spirit of the Nepali people, while the stylised sun represents their fierce resolve . Further, the moon also symbolizes the cool weather of the Himalayas, whereas the sun symbolizes the heat and the high temperature of the Nepali lowlands (Terai). </P>
