The Commonwealth has adopted a number of symbols that represent the association of its members . The English language is recognised as a symbol of the members ' heritage ; as well as being considered a symbol of the Commonwealth , recognition of it as " the means of Commonwealth communication " is a prerequisite for Commonwealth membership . The flag of the Commonwealth consists of the symbol of the Commonwealth Secretariat , a gold globe surrounded by emanating rays , on a dark blue field ; it was designed for the second CHOGM in 1973 , and officially adopted on 26 March 1976 . 1976 also saw the organisation agree to a common date on which to commemorate Commonwealth Day , the second Monday in March , having developed separately on different dates from Empire Day celebrations
