What it is

Shravana Purnima closes Sawan. It is Raksha Bandhan, the day of the thread between brother and sister, and before that it is Shravani, the day the sacred thread is renewed after a river snan, with the rishi tarpan for the seven sages. In the south it is Avani Avittam. So it is a bathing morning first, and the thread ceremonies follow. The date is the day the purnima tithi runs at sunrise; when the tithi begins the day before, the rakhi is tied on the day it holds at sunrise.

Where it is kept

Three of the six waters.

  • Ganga

    Har Ki Pauri, Haridwar

    Purnimanta reckoning

    The Shravani snan at Har Ki Pauri, and the end of the Kanwar month.

  • Triveni Sangam

    Sangam, Prayagraj

    Purnimanta reckoning

    At the Sangam the day is one of the bathing days of the year.

  • Kaveri

    Talakaveri, Kodagu

    Amanta reckoning

    Avani Avittam is the same day in the south, and the Kaveri's people keep it.

The windows

  • Brahma Muhurat

    about 48 minutes

    From sunrise

    Definition
    Two muhurtas of the night before sunrise, until one muhurta before it. A night muhurta is a fifteenth of the night, about 48 minutes at the equinox and longer in winter.

    Brahma Muhurat falls before sunrise, so it belongs to the panchang day that opened at the previous sunrise, and the Gregorian date beside it is the next day. The calendar keeps the two apart.

  • Pratah Snan

    about 96 minutes

    From sunrise

    Definition
    Sunrise, until two muhurtas of the day after it. A day muhurta is a fifteenth of the daylight, about 48 minutes at the equinox and longer in summer.

    This window sits after sunrise, so its panchang day and its Gregorian date agree.

Every time is given at the ghat first, and in your own zone beside it. How the clock is read

Textual basis

The living usage of the ghats named below, and the puranic and dharmashastra literature on the day. A citable edition and passage is still to be added.

Every date here is computed: the tithi at the ghat's sunrise, the month named by the sankranti it holds, and the sun's entry into each sign under the Lahiri ayanamsa. Tithi, nakshatra, sunrise and windows were checked against Drik Panchang for Haridwar on eight days between September 2026 and March 2027, to the minute. The dates roll forward each morning.
