Flag Ratio: 3:5

The national flag of Bangladesh was adopted officially on January 17, 1972. It is based on a similar flag used during the Bangladesh Liberation War of 1971. This flag depicted a map of Bangladesh over a red sun. The map was later deleted from the flag, most likely to simplify the design. The current flag resembles the flag of Japan, except that it has a green field instead of a white one. A red disc is on top of the green field, offset slightly toward the hoist so that it appears centered when the flag is flying. The red disc represents the sun rising over Bengal, and also the blood of those who died for the independence of Bangladesh. The green field stands for the lushness of the land of Bangladesh. [1]
