Start your wheatgrass this RAK Week and enjoy a sign of Spring in just a week or two! In Persian culture, Nowruz (March 20) marks the start of spring and a new year. Zoroastrians put together an elaborate thanksgiving table with symbolic items, including sprouted wheatgrass, as reminders to lead a good life, help each other, and take care of the earth. Bahá’í communities celebrate the spiritual renewal that accompanies the first day of Spring by ending their 19-day fast on Naw-Rúz (March 19—20).
