Vrishabha Sankranti is when Sun moves to Vrishabha Rasi (Taurus zodiac) from Mesha Rasi (Aries zodiac). Sankranti is the time when Sun is changing direction from one Rashi to another.
This day is considered holy to perform Pithru Tharpanam (Rituals to offer the ancestors) and other donations.
Doing “Gho dhaan” (gifting cow) on Vrishabha Sankranthi can save the ancestors at Vaitarani, and doing Bhoodhaan(Gifting a land) can take you to heaven. Doing Pithru Tharpanam on this day can help in getting rid of Pitra Dosh and results in family Accretion.
In every month sun moves from one Rashi to another. There are 12 Sankranti times in a year. Vrishabha Sankranti day is commonly known as Brudha Sankranti in Orissa. Sankramana Snana is performed during Vrushabha Sankranti in many holy places.
