Today is Karkidaka Vavu… We celebrate the Black Vav day in the month of Karkidaka as Karkidaka Vav. On this day, devotees perform sacrifices for Pitrumoksha.
It is believed that sacrifice to Karkidaka Vav will bring peace to the ancestors. A year on earth is this one day for the ancestors. Karkidakam is the first new moon in the Dakshinayana, which is important for the pithris. That is why Karkidaka Vavubali is considered important.
