The national flag of Nepal is a red flag with a blue border around the unique shape of two overlapping right triangles.

Nepal is the only country in the world with triangular flag. All other countries in the world have quadrilateral flags. (Quadrilateral is rectangular or four sided shapes)

The smaller, upper triangle has a white stylized moon and the larger and lower triangle displays a white 12-pointed sun. The color red represents the rhododendron (the National flower of Nepal) and the color red is sign of victory and bravery. The blue border signifies peace and harmony; the two right triangles are a combination of two single pennons (pennants) that originally symbolized the Himalaya Mountains. The moon represents the serenity of the Nepalese people and the shade and cool weather in the Himalayas, while the sun depicts the heat and higher temperatures of the lower parts of Nepal. The moon and the sun are also said to express the strong belief that the Nepal will be there in the earth as long as Sun and Moon are in the sky.

The flag was adopted, with the formation of a new constitutional government, on December 16, 1962. The flag borrows the basic design from the original design, which has been in use for centuries.

The Article 6 of Interim Constitution of Nepal 2007 defines the flag of Nepal. The Constitution also prescribed the method of drawing the unique flag of Nepal.

Article 6 of Interim Constitution of Nepal

“The national flag of Nepal, as handed down by tradition, consists of two juxtaposed triangular figures with a crimson colored base and deep blue borders, there being a white emblem of the crescent moon with eight rays visible out of sixteen in the upper part and a white emblem of a twelve rayed sun in the lower part. The method of drawing the flag and other particulars relating thereto shall be as set out in Schedule 1.”

Method of Drawing Nepali Flag

SCHEDULE 1

(Relating to Article 6)

NATIONAL FLAG

(A) Method of Making the Shape inside the Border

1)On the lower portion of a crimson cloth draw a line AB of the required length from left to right.

2)From A draw a line AC perpendicular to AB making AC equal to AB plus one third AB. From AC mark off D making line AD equal to line AB. Join BD.

3)From BD mark off E making BE equal to AB.

4)Touching E draw a line FG, starting from the point F on line AC, parallel to AB to the right

hand-side. Mark off FG equal to AB.

5)Join CG.

(B) Method of Making the Moon

6)From AB mark off AH making AH equal to one-fourth of line AB and starting from H draw a line

HI parallel to line AC touching line CG at point I.

7) Bisect CF at J and draw a line JK parallel to AB touching CG at point K.

8) Let L be the point where lines JK and HI cut one another.

9) Join JG.

10)Let M be the point where line JG and HI cut one another.

11) With centre M and with a distance shortest from M to BD mark off N on the lower portion of line HI

12)Touching M and starting from O, a point on AC, draw a line from left to right parallel to AB.

13)With centre L and radius LN draw a semi-circle on the lower portion and let P and Q be the points where it touches the line OM respectively.

14) With centre M and radius MQ draw a semi-circle on the lower portion touching P and Q.

15) With centre N and radius NM draw an arc touching PNQ at R and S. Join RS. Let T be the point where RS and HI cut one another.

16)With centre T and radius TS draw a semi-circle on the upper portion of PNQ touching it at two points.

17) With centre T and radius TM draw an arc on the upper portion of PNQ touching at two points.

18) Eight equal and similar triangles of the moon are to be made in the space lying inside the semi-circle of No. (16) and outside the arc of No. (17) of this Schedule.

(C) Method of Making the Sun

19)Bisect line AF at U, and draw a line UV parallel to AB line touching line BE at V.

20)With centre W, the point where HI and UV cut one another and radius MN draw a circle.

21)With centre W and radius LN draw a circle.

22)Twelve equal and similar triangles of the sun are to be made in the space enclosed by the circles of No. (20) and No. (21) with the two apexes of two triangles touching line HI.

(D) Method of Making the Border

23)The width of the border will be equal to the width TN. This will be of deep blue colour and will be provided on all the sides of the flag. However, on the five angles of the flag the external angles will be equal to the internal angles.

24)The above mentioned border will be provided if the flag is to be used with a rope. On the other and, if it is to be hoisted on a pole, the hole on the border on the side AC can be extended according to requirements.

Explanation: - The lines HI, RS, FE, ED, JG, OQ, JK and UV are imaginary.

Similarly, the external and internal circles of the sun and the other arcs except the crescent moon are also imaginary. These are not shown on the flag.
