The flag of Nepal is unique in that it is the only national flag that is not rectangular. It consists of two stacked triangles, symbolizing the Himalayas and the two major religions of the country—Hinduism and Buddhism. Red is the dominant color, representing the bravery and valor of the Nepalese people. Blue is used for the border, symbolizing peace. The upper triangle contains a sun with 12 rays and a crescent moon, symbolizing the hope that Nepal will live as long as the sun and moon, with the sun representing the Rana dynasty and the moon symbolizing the Shah dynasty. The lower triangle features a mountain with snow, reflecting Nepal's Himalayan geography. The flag has been in use since 1962, although the symbols and shape have deep historical roots.
