Gerwis International Children's Day: no central committee
Java-Bode, 26 May 1952, p. 2: Gerwis announces it will celebrate International Children's Day on 1 June with other organisations but form no central committee this year, leaving it to branches; the Jakarta children's week was an experiment approved at the Kongres Wanita Indonesia conference.
