Jamai Shasti is dedicated to the son-in-law and is observed mainly in
Bengal. It is observed on the sixth day during the Shukla Paksha (Waxing Phase of moon) in the month of Jaishto (May – June) in Bengal. Jamai Sashti 2015 date is May 24. In many regions, Goddess Sashti is worshipped on the day for the well being of the children.
'Jamai' means son-in-law and 'Shasti' is the sixth day in a fortnight in a traditional Hindu calendar.
Sons-in-law are invited and honored on the day by the in-laws and is social custom in
Bengal. Mother-in-laws cook special dishes especially Hilsa fish on the day.
The son-in-law is traditionally welcomed to the house and a yellow thread is tied on the wrist. He is given gifts and in return he gifts the mother-in-law. Then a sumptuous dish is served which mainly includes vegetarian and fish dishes.
