What the day is
Shravana nakshatra, the star of Vishnu, kept monthly as a Perumal day. The Vishnu temples keep a special thirumanjanam, and those who cannot fast on Ekadasi often keep this day instead; it is also the birth star of Vishnu's incarnations in the Tamil reckoning and the star of Onam.

- Vishnu, Perumal
- Kind
- Observance Days marked, watched or begun, without a fast or a feast of their own.
Significance
Shravana is the star of Vamana, and of Srinivasa at Tirumala, whose Brahmotsavam ends on it, so in the south it is the Vishnu star of the wheel. Its best-known monthly keeping is at Oppiliappan Koil near Kumbakonam, where the naivedyam of the Perumal is cooked without salt, and devotees keep the Thiruvona vratam by eating nothing salted that day. The name means hearing, and the star is taken as a good one for learning and for listening to the scriptures read.
How it is kept
The puja as a household does it, in order. Tick each step as it is done.

The same day, in every language that has a word for it
Where the regions differ
Tamil Nadu and Kerala mark it monthly; the Thiruvonam in Chingam is Onam, Kerala's festival of the year. The Deccan keeps the same star as Shravanam without a monthly observance.
In other regions
- Tamil Nadu (the dates above)
- Tamil Nadu marks Thiruvonam at the Perumal temples, most famously at Oppiliappan Koil, where the monthly star draws devotees who keep the saltless vratam.
- Kerala
- Kerala remembers Vamana on the star, most of all at the Thrikkakara temple, the home of Onam; the Thiruvonam of Chingam is the great one of the year.
The dates above are the Tamil Nadu 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.

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.

Fixing a day for it
The muhurtham rules for a puja held alongside, whose day the family chooses
Thiruvonam · Shravana's own date is set by the rule in "The hour" above, and no muhurtham moves it. For a temple visit around it, whose day the family does choose, the finder below applies these rules.
A temple visit, or the first darshan at a new temple. No weekday is ruled out: Tuesday belongs to Murugan and the Amman, Saturday to Perumal and Sani, so the day usually follows the deity rather than the almanac. Ashtami and Chaturdasi are the two tithis held back for darshan, with the standing exceptions of Sivaratri on Krishna Chaturdasi and Kala Bhairava Ashtami, which are kept on those very days. Rahu kaal, Yamaganda and Gulika kaal are not scored here; the panchangam page prints them for the day you pick, and most families simply wait them out.
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.
