The Vaisakhi festival Khalsa tradition started in the year 1699,[9] as it is on this day that the 10th Guru of the Sikhs, Guru Gobind Singh laid down the foundation of the Panth Khalsa, that is the Order of the Pure Ones, by baptizing Sikh warriors to defend religious freedoms.[25][26][27] This gave rise to the Vaisakhi or Baisakhi festival being observed as a celebration of Khalsa panth formation and is also known as Khalsa Sirjana Divas[28] and Khalsa Sajna Divas.[29] The festival is celebrated on Vaisakhi day (typically 14 April), since 1699. The Birth of the Khalsa Panth was either on 13 April 1699[30] or 30 March 1699.[31] Since 2003, the Sikh Gurdwara Prabhandak Committee named it Baisakh (Vaisakh), making the first day of the second month of Vaisakh according to its new Nanakshahi calendar.[32]
