Today is Sikh Holy Day. Sikh Holy Day celebrates the Guru Granth Sahib Ji, unique among the world's great scriptures. It is considered the Supreme Spiritual Authority and Head of the Sikh religion, rather than any living person. It is also the only scripture of it's kind which not only contains the works of it's own religious founders but also writings of people from other faiths. Sikhs celebrate the first installation of Sri Guru Granth Sahib Ji on 1st September and the Conferment of title of “Guru” on Sri Guru Granth Sahib Ji on 20th October each year.
