The 13th of February was recommended as the official day due to it being “the day the United Nations established the whole concept of the United Nations Radio, in 1946”. The Board requested that UNESCO's Director-General bring the resolution to the attention of the Secretary-General of the United Nations so that World Radio Day could be endorsed by the General Assembly and celebrated by the whole system. The matter was subsequently treated by UNESCO's General Conference, which adopted the resolution in file 36 C/63. World Radio Day was thus unanimously proclaimed by all member states of UNESCO in November 2011.
