1. International Holiday Calendar
International days are occasions to educate the general public on issues of concern, to mobilize
political will and resources to address global problems, and to celebrate and reinforce
achievements of humanity. The existence of international days predates the establishment of the
United Nations, but the UN has embraced them as a powerful advocacy tool.
