What German World Children's Day (Thuringia) marks

Children's Day is a commemorative date celebrated annually in honour of children, whose date of observance varies by country. In 1925, International Children's Day was first proclaimed in Geneva during the World Conference on Child Welfare. Since 1950, it is celebrated on 1 June in many countries that were part of the Eastern Bloc and Non-Aligned Movement, which follow the suggestion from Women's International Democratic Federation. World Children's Day is celebrated on 20 November to commemorate the issuance of the Declaration of the Rights of the Child by the UN General Assembly on 20 November 1959, along with the adoption of the Convention on the Rights of the Child on that date in 1989. In some countries, it is Children's Week and not Children's Day.
