The date of a festival depends on the place: a tithi that ends at dusk in Chennai can still be running at dusk a thousand kilometres west, which moves the day. Sunrise and sunset here are computed for the place above.

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 Maithil moon festival, kept on the same tithi the rest of India keeps Ganesh Chaturthi, and kept for the moon rather than for Ganesha. The courtyard is swept and plastered, a square is drawn, and on it are set kheer, dahi with chiura, the kheera cucumber, bananas, singhara and the ghevar and the laddu of the season. When the moon is seen the women show it the food, offer water, and only then is anything eaten. Mithila holds that the moon of this night is the one Ganesha cursed and then blessed, and that it must be looked at deliberately rather than avoided, which is the opposite of what the north does on the same evening.

The hour

Clock times for Friday, 3 September 2027 at Chennai

Bhadra Shukla Chaturthi prevailing at pradosha, the two hours and twenty four minutes after sunset, because the whole observance waits on the sight of the moon.

InstantTimeWhat it is
Sunset18:19the moment the sun goes down
Pradosha kala18:19 to 20:43the 2 h 24 min after sunset, the evening worship hour

Sunrise 05:58, sunset 18:19, UTC+5.5. These are the instants the rule is read at, not the temple's own puja times, which every temple prints for itself.

The fast

The women of the house keep a day fast and break it after the moon is shown the offering; the food is the fruit and the sweets of the season, and nothing is cooked with onion or garlic.

Where the regions differ

Mithila and eastern Bihar keep it as Chauth Chandra; the north keeps the same tithi as Ganesh Chaturthi and Maharashtra as the first day of the Ganpati, and both of them avoid looking at this moon rather than worshipping it.

The dates above are the Mithila 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.

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.
