Guru Nanak Jayanti

This day celebrates the birth of Guru Nanak Dev Ji, founder and first Guru of Sikhism. It is considered one of the most important Sikh holy days. Most Sikhs have traditionally celebrated Guru Nanak Jayanti in November, following the Nanakshahi calendar, However, some scholars believe it should be celebrated on Baisakhi Day, usually falling in April. (The Guru was born on Baisakhi Day, April 5, 1469, in what is now Punjab Province, Pakistan.

Two days before the festival, events begin that include Akhand Paath, a 48-hour reading of the Guru Granth Sahib at gurdwaras (temples). The next day, Sikhs visit the gurdwara to chant hymns and hold Nagar Kirtan. On the festival day, celebrations include readings, music, and assemblies. At langars, or community kitchens, volunteers serve food and a special sweet called karah prashad.
