Guru Nanak Gurpurab is one of the holiest festivals in Sikhism. Besides Sikhs, Hindus and other followers of Guru Nanak Dev Ji's philosophy also celebrate this festival.
Holidays in the Sikh religion revolve around the anniversaries of the 10 Sikh gurus, who were responsible for shaping the beliefs of the Sikhs. Their anniversaries, known as Guru Nanak Gurpurab (or Gurpurb), are occasions for celebration and prayer among Sikhs.
Guru Nanak Dev Ji, the founder of Sikhism, was born on April 15, 1469 in Rai-Bhoi-Di Talwandi, Shekhupura, a District of Pakistan, now Nankana Sahib. In the Gregorian calendar the celebration usually falls in the month of November, but its date varies from year to year depending on the traditional dates of the Indian calendar.
