The Fast is a special period of restraint observed in the last month of the Bahá'í year. It is preceded by the joyous days of Ayyám-i-Há and followed by the celebration of Naw-Rúz (Bahá'í New Year).

Through simple, melodic rhymes, this book teaches the meaning, purpose, and spiritual atmosphere the Fast and Naw-Rúz creates around the world.

Over 24 countries and 20 languages are represented in the books Celebrating Ayyám-i-Há Around the World and Observing the Fast & Celebrating Naw-Rúz Around the World.
