These observances serve as key moments to engage governments, organizations, and individuals in advancing peace, sustainable development, human rights, and international cooperation. Rooted in United Nations resolutions and supported by UN system entities, each observance reinforces the values of the UN Charter and the commitments outlined in the 2030 Agenda for Sustainable Development.
