Here is list of those Indian celebrities who celebrates their birth day on 15th April.
(1) Guru Nanak Dev (Born: 15th April 1969 at Nankana Sahib, Died : 22 September 1539 at Katarpur Sahib) – Guru Nanak was an Indian spritual teacher, mystic and poet, who is regarded as the founder of Sikhism and is the first of the ten Sikh Gurus. Nanak is said to have travelled far and wide across Asia teaching people the message of Ik Onkar (ੴ, ‘One God’), who dwells in every one of his creations and constitutes the eternal Truth. With this concept, he would set up a unique spiritual, social, and political platform based on equality, fraternal love, goodness, and virtue. Nanak’s words are registered in the form of 974 poetic hymns, or shabda, in the holy religious scripture of Sikhism, the Guru Granth Sahib, with some of the major prayers being the Japji Sahib (jap, ‘to recite’; ji and sahib are suffixes signifying respect); the Asa di Var (‘Ballad of Hope’); and the Sidh Gosht (‘Discussion with the Siddhas’). It is part of Sikh religious belief that the spirit of Nanak’s sanctity, divinity, and religious authority had descended upon each of the nine subsequent Gurus when the Guruship was devolved on to them. His birthday is celebrated as Guru Nanak Gurpurab, anually across India.
(2) Guru Arjan Dev (Born: 15th April 1563 at Goindval, Died: 30 May 1606 at Lahore) – He was the fifth of the ten total Sikh Gurus. He compiled the first official edition of the Sikh scripture called the Adi Granth, which later expanded into the Guru Granth Sahib. He is regarded as the first of the two Gurus martyred in the Sikh faith. Guru Arjan was born in Goindval, in the Punjab, the youngest son of Bhai Jetha, who later became Guru Ram Das, and Mata Bhani, the daughter of Guru Amar Das. He completed the construction of the Darbar Sahib at Amritsar, after the fourth Sikh Guru founded the town and built a sarovar. Arjan compiled the hymns of previous Gurus and of other saints into Adi Granth, the first edition of the Sikh scripture, and installed it in the Harimandir Sahib.
