In Bengali households this weekend, sons-in-law will be fed before anyone else, fanned with a palm-leaf hand fan, and sent home with a bag of sweets they didn't ask for. It happens every year, and it has a name: Jamai Sasthi.

This year, the festival falls on Saturday, 20 June 2026, corresponding to the 4th of Ashadh, 1433 in the Bengali calendar. According to the Bishuddha Siddhanta Panjika, the Sasthi tithi begins at 4:59 pm on Friday, 19 June, and ends at 3:46 pm on Saturday, 20 June 2026. The festival is observed on the sixth day, or Sasthi, of Shukla Paksha in the month of Jyestha - and that timing isn't incidental. Among followers of Hinduism, the day is regarded as both a social and spiritual occasion, dedicated to the worship of Goddess Sasthi, the divine protector of children.

Why A Son-In-Law Gets A Festival Of His Own

Jamai Sasthi is a traditional cultural ritual of Bengali Hindus, observed on the sixth tithi of the Shukla paksha of the Joishtho month, and it is built around one simple idea: the daughter's new family is invited home, fed well, and honoured. The festival has its roots in a time when daughters often moved far from their parental homes after marriage, and Jamai Sasthi became the occasion for families to reunite.

The mythology behind it is older and stranger than the modern celebration suggests. A popular folktale describes a housewife who wrongly blamed the goddess's vehicle, a cat, for a theft. The angry goddess took her child away, returning him only after the woman observed a strict fast to please her. That fast, retold across generations, is the origin of the Sasthi vrat that mothers-in-law still keep today. The day is also called 'Aranya Sasthi,' from a time when people worshipped nature by recreating a symbolic forest or performing the rituals within one.

What Happens On The Day

The rituals are unhurried and specific. Mothers-in-law wake early, bathe, dress in new clothes, and perform the puja for Goddess Sasthi before the son-in-law even arrives. When he does, the welcome follows a set sequence:

• An aarti, followed by a tilak of curd or sandalwood applied to the forehead
• A holy yellow thread from the puja tied around the wrist, along with blessings of paddy and durva grass
• The mother-in-law fanning her son-in-law with a new palm-leaf fan, chanting "Shaat-shaat-shaat" three times for a long, protected life
• A plate of six fruits is touched to his forehead, after which holy water is sprinkled over everyone present

Gifts move in both directions - the son-in-law usually receives new clothes or something valuable, while he, in turn, brings sweets, fruit, and presents for his in-laws. None of it is symbolic alone. After the puja, the mother-in-law feeds her son-in-law with visible affection, often turning the meal into the centrepiece of the day.

The Food Is Not An Afterthought

Bengali Jamai Sasthi spreads are famously generous, and largely fixed by tradition. Luchi, ilish (hilsa) curry, aloor dom, sandesh, and mishti doi are the dishes most commonly served - a combination that leans on the season's best hilsa and the sweet-shop staples Bengal is known for. In many homes, the meal itself functions as the real ritual: a long, indulgent lunch that lasts well into the afternoon.

Bottomline

Strip away the fanning and the yellow thread, and Jamai Sasthi is really about a family insisting, once a year, that the person their daughter married still belongs at their table. The puja gives it shape, the food gives it warmth, and the timing - this Saturday, 20 June - gives Bengali households across the world a reason to set an extra, very well-fed place at lunch.
