Guru Nanak Jayanti is a significant festival celebrated by Sikhs around the world to honor the birth of Guru Nanak Dev Ji, the founder of Sikhism. This day usually falls in November and is marked by various religious activities, including prayers, singing hymns, and community service. The celebrations often begin with a special prayer service called Akhand Path, which is a continuous reading of the Guru Granth Sahib, the holy scripture of Sikhism. Devotees also participate in processions, known as Nagar Kirtan, where they sing devotional songs and share food with the community, emphasizing the values of equality and service.
