This day is also observed as the beginning of the Hindu solar new year celebrated by the people of Nepal and India in Assam Valley, Kerala, Orissa, West Bengal and some other regions of India. The particular significance attached to the occasion shows regional variation outside of Punjab too.
The festival is celebrated as
- Rongali Bihu in Assam,
- Naba Barsha or Pohela Boishakh in Bengal and Tripura, *Puthandu (Tamil New Year) in Tamil Nadu,
- Vishu (or Vaishakhi) in Kerala,
- Bikhu or Bikhauti in the Kumaon region of Uttarakhand,
- Maha Vishuba Sankranti (or Pana Sankranti) in Orissa, and the
- Sinhalese New Year festival in Sri Lanka.
Hinduism and Sikhism have several religious calendars, some places of worship accept one version and others use a different version. This means it is not possible to say that a festival will always fall on the same day in the western Gregorian calendar.
