Gurupurab means the "festival of the Gurus". The sikh festivals are celebrated as Gurupurabs. Every morning, for three weeks before any Gurupurab, there are processions through the streets of a town called Prabhat Pheris, these early-morning processions have Sikhs going around localities singing hymns. Those marching in the procession are offered sweets and tea by the faithful. The Gurupurab day signals the end of the Prabhat Pheris.Beginning three days before the holy day, the Sikh holy book - the Guru Granth Sahib - is read continuously, from beginning to end, without break, in the gurudwaras. This is known as the akhand path. The reading concludes on the day of the festival. All Gurpurabs are considered auspicious and important but special significance is accorded to the birth anniversary of Guru Nanak, in the month of Kartik.
