Gurupurab, also known as Guru Nanak Gurpurab, is one of the most significant festivals in Sikhism, celebrating the birth anniversary of Guru Nanak Dev Ji, the founder of Sikhism and the first of the ten Sikh Gurus.

The event typically falls in the month of November according to the Nanakshahi calendar. Gurupurab is marked with great fervor and devotion by Sikhs around the world. The celebrations often include early morning processions known as Nagar Kirtan, where devotees sing hymns and carry the Sikh flag, the Nishan Sahib. Gurdwaras, the Sikh places of worship, are adorned with lights and decorations, and special prayers and kirtans (devotional songs) are organized.
