On December 14, 1954, the UN General Assembly recommended that all countries observe a Universal Children's Day to promote solidarity among the world's children and awareness of their wellbeing. November 20 gained particular significance as the date the Assembly unanimously adopted the Declaration of the Rights of the Child on November 20, 1959, and later the Convention on the Rights of the Child — the most widely ratified human rights treaty in history — on the same date in 1989. The day promotes children's wellbeing worldwide and reaffirms their fundamental rights to health, education, protection from violence and exploitation, and participation in decisions affecting them. It also serves as a platform to highlight pressing children's issues such as child labor, child marriage, and the impact of armed conflict on young lives. UNICEF and child-focused organizations worldwide mark the day with events giving children a voice, including symbolic roles in governments and institutions for a day, alongside landmarks lit in blue in support of children's rights and awareness campaigns engaging schools and families.
