Use Old flag of Nepal before 1962

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). Its crimson red is the colour of the rhododendron, the 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 modernise the flag.

The current flag was adopted on 16 December 1962, along with the formation of a new constitutional government[citation needed]. It borrows from the original design, used throughout the 19th and 20th Centuries, and is a combination of the two individual pennons used for more than 2,000 years.[citation needed]

## Symbolism

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[citation needed]. The triangular shape of the pennons represent the Himalayas.

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. Additionaly, the stylised moon represents the calm demeanour and purity of spirit of the Nepali people, while the stylised sun represents their fierce resolve[citation needed]. Further, the moon also symbolises the cool weather of the Himalayas, whereas the sun symbolises the heat and the high temperature of the Nepali lowlands (Terai).

### Aspect ratio

According to the stated geometric construction law, the circumscribed rectangle has an irrational ratio of:

${\displaystyle 1:{\frac {6136891429688-306253616715{\sqrt {2}}-{\sqrt {118-48{\sqrt {2}}}}\left(934861968+20332617192{\sqrt {2}}\right)}{4506606337686}}}$

≈ 1:1.21901033… ().[2] This ratio is the least root of the quartic polynomial[3]

${\displaystyle 243356742235044r^{4}-1325568548812608r^{3}+2700899847521244r^{2}-2439951444086880r+824634725389225,}$

and arises from the addition of the blue border after construction of the red field. The bounding rectangle of the red field alone has the rational aspect ratio 3:4 (=1:1.333…).[1]

## Incorrect versions

This is the flag of Nepal used for the 2016 Summer Olympics. It has the transparency turned off.

The shape of the flag of Nepal is difficult to reproduce, and is often is used incorrectly. These typically have a white area to make the flag a 3:2 ratio, an example is the Nepalese Flag used at the 2016 Summer Olympics.[4]
