The national flag of Singapore was designed by a committee, headed by Toh Chin Chye (Dr). It consists of two equal horizontal sections, red above white, where the red segment has a white crescent moon beside five stars placed in a circle. The national anthem, Majulah Singapura, the state crest and the national flag were incorporated on 3 December 1959 during National Loyalty Week. The flag replaced the Union Jack which had previously flown over Singapore.
