The national flag of Bangladesh was adopted officially on 17 January 1972. It consists of a red circle on top of a dark green banner. The red circle is offset slightly toward the hoist so that it appears centred when the flag is flying. While there are numerous interpretations, the green of the flag symbolises the lush landscape of Bangladesh, and the red circle, reminiscent of the rising sun, represents the sacrifice made by the people during the Liberation War of 1971.
