Why do you celebrate vaisakhi?

Vaisakhi is an ancient harvest festival in Punjab, which also marks beginning of a new solar year, and new harvest season. Vaisakhi also has religious significance for Sikhs.[1] It falls on the first day of the Vaisakh month in the solar Nanakshahi calendar, which corresponds to April 14 in the Gregorian calendar.

In Sikhism, it is one of the most significant holidays in the Sikh calendar, commemorating the establishment of the Khalsa at Anandpur Sahib in 1699, by the 10th Sikh Guru, Guru Gobind Singh. It also marks the beginning of the Sikh new year.[2][3].

This day is also observed as the beginning of the Hindu solar new year celebrated by the people of Nepal and India in Kerala, Orissa, Tamil Nadu, West Bengal and some other regions of India. The particular significance attached to the occasion shows regional variation outside of Punjab too. In Himachal Pradesh, the Hindu Goddess Jwalamukhi is worshipped on Vaisakhi, while in Bihar, the Sun-god Surya is honoured.[4] The festival is celebrated as Rongali Bihu in Assam, Naba Barsha or Pohela Boishakh in Bengal, Assam and Tripura, Puthandu (Tamil New Year) in Tamil Nadu, Vishu (or Vaishakhi) in Kerala, Maha Vishuba Sankranti (or Pana Sankranti) in Orissa, and the Sinhala and Tamil new year festival in Sri Lanka. Besides Punjab, Vaisakhi is widely celebrated as traditional harvest festival in many northern states of India, such as Haryana, Himachal Pradesh and Uttarakhand.
