Kula Mangalbar is observed in certain parts of eastern India especially in some parts of Bengal. As the name ‘Mangalbar’ indicates, the ritual is observed on Tuesdays. The Kula Mangalbar ritual is partly dedicated to Surya or Sun God and to two of his sons who are part of regional folklore. Interestingly, none of the gods from Hindu Pantheon are worshipped on the day. The main Kula Mangalbar ritual involves pujas with seventeen pumpkins and seventeen pumpkin leaves. The pumpkins and the leaves are placed on a copper vessel smeared with red sandalwood paste. An interesting story of Surya or Sun God having twin sons is read or listened to by those performing the ritual.
