Palm Sunday is celebrated by Western Christians to mark the entry of Jesus into the city of Jerusalem shortly before his arrest and execution on a charge of heresy, as reported in the Christian Gospels. In many churches on this day, palm leaves are distributed in keeping with the palm fronds laid by his followers at the feet of the donkey upon which Jesus rode into the city on that day. For information regarding Christianity, see January 5th, “Christmas Eve.”
The Birthday of Guru Gobind Singh is celebrated by Sikhs on the anniversary of the 1666 birth of the poet and warrior whom the faithful hold to have been the tenth and last prophet of God, who completed the Sikh holy book and established it as the eleventh, final and living Sikh Guru (the Guru Granth Sahib), dying on October 7, 1708. Sikhism is a non-anthropomorphic monotheistic religion based upon the teachings of Guru Nanak Dev, whom the faithful hold to have been the first of ten prophets of God (or Gurus [Sanskrit; in English, “Teachers”]) who was born in India in 1469 and died in 1539.
