Día del Niño
Since 1939, Government-General of Chosen, viewing Children's Day as one of the nationalist movement by Korean independence activists, had oppressed the Children's Day celebration. Since 1945, Children's Day celebration has been resumed. The children's welfare law written in the constitution officially designated 5 May as Children's Day in 1961. And by 'the law of holiday of government office', Children's day became a holiday in Korea in 1970.
