March 20

The pure-hearted people of Iran, following a tradition stretching back several thousand years, observe as a national festival this day [Naw-Ruz] that marks the commencement of spring. They put aside all grievances from the preceding year and focus their thoughts on loving fellowship. Bahá’ís across the globe, of every nation and ethnicity, likewise celebrate with great jubilation the festival of Naw-Rúz, as explicitly ordained in the Most Holy Book, and regard it as an opportunity to foster friendship and unity among the peoples of the world.
