Worked out for Chennai, Lahiri ayanamsa. A date is a function of the place: set yours above and the next three come back for where you are.

What the day is#

The full moon of Shrawan, on which Brahmin and Chhetri men change the janai, the sacred thread, after a bath and the Rishi Tarpani, and everyone else has a yellow doro tied on the wrist by a priest. The doro is worn until Laxmi Puja and then tied to the tail of a cow. Kwati, a soup of nine sprouted beans, is cooked in every house, and the pilgrimage is to the lake at Gosaikunda and to Kumbheshwar in Patan, whose tank is held to be fed from it.

Deity
Shiva, Varuna, Gayatri
Kind
Festival Days of celebration: the house is decorated, a feast is cooked and the temple is visited.

Significance#

The janai is the vow of learning worn on the body, and changing it each year on this full moon renews the promise to keep the discipline it stands for. The yellow doro that everyone else has tied on the wrist carries the protection of the same rite to the whole household, men and women, children and elders alike. It is kept until Laxmi Puja, when it is tied to a cow's tail, since the cow is held to help the soul across the river of death. The kwati, nine sprouted beans cooked together, is eaten at the turn of the monsoon to put strength back into bodies worn out by the planting, which is as much an elder's reason as any.

How it is kept#

The puja as a household does it, in order. Tick each step as it is done.

Keep ready

  • a new janai
  • yellow doro threads
  • nine kinds of beans for the kwati
  • flowers, rice and red tika powder
  • a lamp and incense
  • dakshina for the purohit
  • a copper vessel of water for the tarpan

What is cooked#

Kwati is the dish of the day: a thick soup of nine sprouted beans, among them black gram, green gram, chickpea, soy beans, field peas, kidney beans and cowpeas, with ajwain, ginger and garlic, the nine varying from house to house. It is eaten with beaten rice or plain rice, and the men who change the janai eat only after the rite.

Only the names actually in use are listed. A blank script is not an omission: the day may simply not be kept there, or be kept under a different festival's name.

Where the regions differ#

Nepal ties the doro and eats the kwati; the same full moon is Raksha Bandhan in north India, the Upakarma in the south and the Deccan, Narali Purnima on the Konkan coast and Jhulan Purnima in Bengal.

In other regions

Tamil Nadu
Tamil Nadu changes the thread on the same day as Aavani Avittam, with the Gayatri japam the day after.
Telugu
The Telugu country calls it Jandhyala Pournami, the full moon of the sacred thread.
North India
North India keeps the same full moon as Raksha Bandhan, the sister tying the rakhi on her brother, with the sacred thread changed at the Shravani Upakarma in Brahmin homes.
Maharashtra
The Konkan coast keeps it as Narali Purnima, with a coconut given to the sea.
Nepal (the dates above)
Nepal keeps it as Janai Purnima: the janai changed, the doro tied, the kwati cooked, with pilgrims at the lake of Gosaikunda and at Kumbheshwar in Patan, whose tank is held to be fed from it.

The dates above are the Nepal reckoning, because that is the calendar this key belongs to. Switch the tradition on the calendar page to see how another one dates the same day.

Your family's own temple comes first, and its calendar is the one that decides.

A temple is listed here only where the gazetteer's own line names this day, or where this day's own entry names the town, or where the day belongs to the ancestors or the nagas and the temple is recorded for that rite. Where neither table says anything, nothing is listed as kept for the day; where fewer than three are, the nearest temples of the day's own gods are added under a heading of their own.

Mantras#

The prayers said with the day. Each opens with its words and meaning.

Every date here is computed from the Sun and Moon for the place entered, by the rule printed beside it.

A printed panchangam can differ by a day where an almanac reads a tithi at a different instant, and a family's own custom always comes first. Where the practice genuinely varies, the text says so rather than choosing for you.
