The closing day of the solar year — the day before the sun enters Mesha and the solar new year begins as Vishu, Puthandu, Poila Boishakh, and Bihu, back at the top of this chapter. Odisha and Bengal mark it as Pana Sankranti and Chaitra Sankranti respectively — the ledger of one year closing just as another opens.
चैत्र मास का अंतिम दिन
Odisha's Pana Sankranti is also observed in some local calendars as the traditional birthday of Hanuman, layering a second observance onto the same date.
A cooling drink, pana, mixing fruit, milk, and spices, is prepared and shared, giving the Odia festival its name.
