World Play Day is celebrated internationally on 28 May each year. This day commemorates the day in 1987 when the International Toy Library Association (ITLA) was first proposed.
Dr Freda Kim recommended this day at the 8th International Toy Library Conference in Japan in 1999. Dr Kim is a British play advocate and teacher. During a board meeting in Italy in 2001, the date was decided and WPD has been celebrated annually ever since.
