March 19

Among the ancient Persians this day [Naw-Ruz] was looked upon as the holy day of the year - a day when hospitals and charitable institutions were founded, collections for the poor were made and every effort put forth that it might not be allowed to pass without leaving some divine trace and throughout Persia one sees these historical traces.
