Baisakhi day is observed as the Naba Barsha (New Year) in Bengal. On April 14, the people take a ritual bath in the River Ganga or any other river or a nearby tank and decorate their houses with rangoli (floral patterns) drawn at the entrance of their homes with a paste made of rice powder.

In Assam, this is the day for the Rongali Bihu, which is a chance for the young people of the state to dress up in their traditional finery and dance the night away. There too, this is the harvest festival, which allows the farmers to relax and enjoy before they take up the task of harvesting their crop.

Baisakhi festival is celebrated twice a year in Himachal Pradesh in the honour of Goddess Jwalamukhi. In the months of Vaishakha (April-May) and Kartika (November), the Himachalis worship the Goddess whose image near a hot spring issues forth flames.

In the South, Baisakhi is celebrated to mark the Tamil and Telugu New Year. In a ceremonial march, people take out wooden chariots in a procession. The temples in Kerala celebrate Pooram festivals usually in honor of Vishnu at this time. Among them, the Pooram observed in the Vaddakunathan Swamy (Shiva) temple of Trichur is famous.

The state of Bihar state celebrates a festival in Vaishakha (April) and Kartika (November) in honor of the Sun God, Surya, at a place called Surajpur-Baragaon. This is essentially a village where, according to an ancient practice, people bathe in the temple tank and pay obeisance to the Sun God while offering flowers and water from the sacred river Ganga.
