The Day of Interethnic Harmony and Cultural Diversity is observed in Ukraine every May 21, coinciding with the UN World Day for Cultural Diversity for Dialogue and Development. Established by President Volodymyr Zelenskyy in December 2024, the holiday aims to strengthen unity among the diverse ethnic groups in Ukraine, which includes over 100 different communities such as Crimean Tatars, Russians, Jews, and Poles. While not a public holiday, the day is marked by various events organized by government agencies, educational institutions, and cultural centers, emphasizing mutual respect, tolerance, and the importance of cultural diversity. The celebration also highlights the rights of national minorities as defined by the Law on National Minorities adopted in 2022, promoting their cultural identity and participation in social life. The day serves as a reminder of the contributions of these communities to Ukraine's sovereignty and independence.
