Ganesh Chaturthi 2027: Sthapana Muhurat and Vidhi

The Date and the Chaturthi Tithi (गणेश चतुर्थी 2027: तिथि)

Ganesh Chaturthi is the fourth tithi of the bright fortnight of Bhadrapada, kept as the birthday of the deity the classical texts call Vighnaharta, the remover of obstacles, and Vinayaka. Elsewhere in India the same day is Vinayaka Chaturthi or Vinayaka Chavithi, and in Maharashtra the ten days it opens are Ganeshotsav. In 2027 it falls on Saturday, 4 September 2027.

The tithi itself runs from 14:19 on 3 September 2027 to 12:26 on 4 September 2027 at New Delhi. Read those two instants carefully, because they are not symmetrical about either date: the chaturthi opens in the early afternoon of one day and closes before midday of the next, so it holds one full night and two part-days and it is genuinely unobvious which of the two dates the festival belongs to. That is exactly the situation a day-part rule exists to settle, and this festival has one.

One consequence of the same window is worth flagging at the start. The tritiya that holds sunrise on 3 September 2027 is Hartalika Teej, which in 2027 falls on that date — so the two observances sit back to back, the teej fast on one day and the sthapana on the next, which is a common enough arrangement but catches households that plan for only one of them.

The Madhyahna Rule, Worked From the Two Instants (मध्याह्न)

The row for this festival carries the rule tithi at madhyahna, and it is the single most useful line on the page. Madhyahna is not a loose word for midday. Daylight is divided into five equal parts — pratah, sangava, madhyahna, aparahna, sayahna — and madhyahna is the third of them. It therefore has to be computed from each date’s own sunrise and sunset, and it is a different window on the two dates the chaturthi touches.

• 3 September 2027: sunrise 06:00, sunset 18:40, so 12h 40m of daylight and madhyahna runs 11:04–13:36, a window 152 minutes wide.
• 4 September 2027: sunrise 06:00, sunset 18:39, so 12h 39m of daylight and madhyahna runs 11:04–13:35, 151 minutes wide.
• The chaturthi: 14:19 on 3 September 2027 to 12:26 on 4 September 2027.

Now put them together. On 3 September 2027, madhyahna has already closed at 13:36 and the chaturthi does not begin until 14:19 — 43 minutes too late. The tritiya, not the chaturthi, is what runs through madhyahna that day, and by the rule the row gives, that date cannot be Ganesh Chaturthi at all. On 4 September 2027, madhyahna opens at 11:04 and the chaturthi is still running; it holds until 12:26, which is inside the window. So the chaturthi prevails at madhyahna on 4 September 2027 and on no other date, and the sthapana belongs there. That is the entire derivation, and it took two instants and two sunsets.

It is worth seeing what a different rule would have done with the same window, because this is where most published disagreement comes from. A pradosh rule — the tithi running after sunset, which is how Diwali and Dhanteras are fixed — would have named 3 September 2027: the chaturthi is running at sunset that evening (18:40) and is long over before sunset on 4 September 2027 (18:39). A sunrise rule happens to agree with madhyahna this year, because the chaturthi already holds at sunrise on 4 September 2027; in years when the tithi begins mid-morning it does not agree, and the madhyahna rule is precisely what stops the festival sliding a day in those years. Three defensible rules, two different answers, and the row tells you which one applies.

The Sthapana Window This Produces

The sthapana wants madhyahna and it wants the chaturthi, so the window is the overlap of the two: 11:04 to 12:26 on 4 September 2027, which is 82 minutes. That is the honest answer, and it is narrower than the round morning slots that circulate every year. Before 11:04 madhyahna has not begun; after 12:26 the chaturthi has gone. Anyone printing a window outside those bounds is printing something other than what the rule asks for.

• Sthapana window (New Delhi): 11:04–12:26, 82 minutes, being madhyahna from 11:04 intersected with the chaturthi to 12:26
• Rahu Kaal: 09:10-10:45 — it clears 19 minutes before the window opens, so there is no conflict, but it does rule out the mid-morning that people often prefer
• Abhijit Muhurat: 11:54-12:45 — its first 32 minutes fall inside the sthapana window, which is the narrowest and most conservative slot available on the day
• Brahma Muhurat: 04:24-06:00 — for the morning bath and japa, not for the sthapana, which has to wait for madhyahna
• Yoga and karana at sunrise: Shukla and Vishti

Every clock figure above is computed for New Delhi from the JPL DE421 ephemeris. Because madhyahna is derived from sunrise and sunset, it moves with your longitude — the window opens later in the east of the country and earlier in the west, by up to roughly an hour — while the two tithi instants are absolute and hold everywhere. If you are installing the murti in another city, recompute the overlap against your own sunrise and sunset, or take it from a local panchang. A single national sthapana muhurat is not a thing that exists.

Hasta in the Table, Chitra at Sunrise (नक्षत्र)

Here the two tables behind this page give different answers, and the difference is instructive rather than a defect. The festival row names Hasta; the daily panchang gives Chitra at sunrise on 4 September 2027. Both are right, because they are taken at different moments. At sunrise on 3 September 2027 the Moon is in Hasta, and by sunrise on 4 September 2027 it has moved into Chitra — the crossing falls somewhere in between, which is the same interval in which the chaturthi begins. The festival row records the nakshatra around the onset of the tithi; the daily row records the one holding at the next sunrise.

For the record, Hasta is ruled by Moon with Savitar for its presiding power and Hand for its symbol, spanning Virgo 10°00′ – 23°20′ in Deva gana; Chitra, which is what actually holds the morning of the sthapana, is ruled by Mars under Vishvakarma, with Bright jewel for a symbol. Neither of them is a condition on anything.

That last point deserves its own sentence, because the opposite is asserted constantly. No nakshatra is required for the sthapana and none is preferred. The tithi and the day-part rule fix the date between them, and the nakshatra is whatever the Moon is doing at the time — it changes every year and nobody chooses it. Advice to wait for a particular nakshatra before installing the murti is advice about a decision that is not yours to make. If you want the day read against your own chart, that is a kundli question rather than a festival one, and Hasta nakshatra covers this one in full.

The Sthapana and the Sixteen Upachara (स्थापना और षोडशोपचार)

The sequence is old and reasonably stable. The murti is brought in, the chowki is cleaned and covered, a bed of akshata or rice is laid, and the murti is placed facing east or north. Water is set in a kalash to the right. The priest or the head of the household does achamana and pranayama, then sankalpa, naming the tithi, the paksha, the place and the purpose. Then comes pranapratishtha, the invocation of presence into the image, usually with the Ganapati Atharvashirsha or the relevant suktas — and this is the step for which madhyahna is being kept, so it is the one that has to sit inside the window above.

Worship proper is shodashopachara, sixteen services, offered in order. Paddhatis differ slightly in how they group the last few, so treat this as the common shape rather than the only list:

• 1–2. Avahana and asana. Invocation, then the offering of a seat.
• 3–5. Padya, arghya, achamaniya. Water for the feet, water for the hands, water to sip — the three courtesies owed to any guest.
• 6. Snana. Bathing, commonly panchamrita followed by clean water.
• 7–8. Vastra and yajnopavita. Cloth, and the sacred thread.
• 9–10. Gandha and pushpa. Chandan, then flowers — with durva grass, offered in bunches of three or five blades up to twenty-one, which is the one offering particular to this deity. Red flowers and hibiscus are traditional; tulsi is traditionally withheld here.
• 11–12. Dhupa and dipa. Incense, then the lamp.
• 13. Naivedya. Modak above all, ukadiche modak steamed in rice flour in Maharashtra and fried elsewhere, with laddoo, kozhukattai or kadubu depending on the region.
• 14. Tambula and dakshina. Betel leaf with areca, and the offering set beside it.
• 15. Nirajana. Aarti with camphor; Sukhakarta Dukhaharta in Maharashtra, Jai Ganesh Deva across the north.
• 16. Pradakshina and namaskara. Circumambulation and prostration, then the prarthana that closes the puja.

After the first day the puja is repeated morning and evening for as long as the household keeps the murti, with naivedya each day and aarti at least in the evening, and the twenty-one durva are usually the constant. A long-standing custom avoids looking at the Moon on the evening of the chaturthi; the account attached to it in the Puranas is the Syamantaka episode, and it is a custom rather than a rule, observed in some families and not others.

The Days Kept, and the Visarjan Tithi (विसर्जन)

Visarjan is a tithi and not a date somebody liked. The ten-day immersion falls on Anant Chaturdashi, which in 2027 is Tuesday, 14 September 2027, with the chaturdashi running 00:40 on 14 Sep to 02:48 on 15 Sep — so the whole of the daylight on that date is inside the tithi at New Delhi. Sunrise 06:05, sunset 18:27, Abhijit 11:51-12:41, Rahu Kaal 15:22-16:55, and the Moon in Dhanishta. Immersion follows the farewell aarti at whatever hour suits the procession, and the only conventional avoidance is Rahu Kaal, which that day sits in the afternoon.

Not every household keeps ten days. A day and a half, three, five, seven and ten are all normal, counted in tithis rather than in dates, and in 2027 the two counts happen to run together: from the sthapana to Anant Chaturdashi is 10 tithi steps across 11 calendar dates, with no tithi doubled and none dropped, so the nth day of your count is also the nth date. That is not guaranteed in other years, which is why the table below gives the tithi at sunrise for every date in the stretch rather than a list of days.

The visarjan itself is brief: uttarpuja, a last naivedya, the aarti, the murti lifted with the akshata from under it, and in many families a handful of rice and curd carried along. The chant is Ganpati Bappa Morya, pudhchya varshi lavkar ya. Clay murtis and natural colours immerse without doing damage, plaster ones do not, and most municipalities now provide artificial tanks; using them is not a compromise on the rite, since what the tradition asks for is water, not a particular water body.

Regional Variation

Maharashtra keeps the largest version. Household sthapana runs alongside the public mandals, an arrangement that dates from the late nineteenth century in Pune and turned a domestic rite into a civic one; the Jyeshtha Gauri observance falls within the same stretch and brings a second set of installations into many homes. Goa keeps it as Chovoth with the matoli, a canopy of seasonal produce hung above the murti.

In Karnataka the day is Gauri-Ganesha, the mother installed before the son, with kadubu and chakli; Tamil Nadu keeps Vinayaka Chaturthi with kozhukattai and a shorter observance, often a single day; Andhra Pradesh and Telangana keep Vinayaka Chavithi with the twenty-one patri, the twenty-one named leaves offered in sequence, and undrallu. Kerala’s Vinayaka Chaturthi is centred on temple worship rather than home installation. The vidhi above is the common core; the food, the length and the scale are local, and none of the local versions is a deviation from a national standard, because there is no national standard.

In Short

Ganesh Chaturthi 2027 is Saturday 4 September 2027, and the reason is the rule the table carries: the chaturthi runs 14:19 to 12:26, madhyahna on 3 September 2027 closes at 13:36 before the tithi has begun, and madhyahna on 4 September 2027 opens at 11:04 while it is still running. The sthapana window that follows is 11:04 to 12:26 at New Delhi, 82 minutes. Visarjan for households keeping ten days is Anant Chaturdashi, 14 September 2027.

Nothing above is a figure somebody remembered. If you want the same window recomputed for your own sunrise and sunset, or the puja arranged around a working day, that is worth ten minutes with someone who can do the arithmetic for your city rather than for New Delhi.
