Ganesh Chaturthi 2026: Sthapana Muhurat and the Madhyahna Rule
Ganesh Chaturthi 2026 falls on Monday, 14 September — the Shukla Chaturthi begins at 7:08 AM in Delhi and prevails through the madhyahna, the midday period the sthapana rule keys on. The engine-verified installation window: Abhijit Muhurat 11:52 AM–12:41 PM, with Monday's early Rahu Kaal safely out of the way.
Ganesh Chaturthi 2026 falls on Monday, 14 September. In Delhi the Shukla Chaturthi tithi begins at 7:08 AM that morning — Tritiya ends with sunrise barely past — and prevails through the middle of the day, which is the part that matters: the classical rule fixes the festival to the day Chaturthi rules the madhyahna, the midday period held to be Ganesha’s birth time. The engine’s computation and basis are on the Ganesh Chaturthi festival page.
The sthapana window, engine-verified
The murti installation — pran pratishtha — belongs to the madhyahna, and the cleanest engine-verified anchor inside it is the Abhijit Muhurat: 11:52 AM – 12:41 PM for Delhi. One caveat read straight from the full-day table: the bare choghadiya lanes crossing midday that Monday are Rog (10:44 AM – 12:16 PM) and Udveg (12:16 – 1:49 PM) — mediocre lanes that the Abhijit window overrides for this purpose. The madhyahna rule and the Abhijit rule agree here, and that agreement — not a single almanac line — is what the window rests on. How Abhijit earns that standing is covered in Abhijit Muhurat: the daily universal window.
Monday’s Rahu Kaal is early — that’s good news
Rahu Kaal runs 7:39 – 9:12 AM on a Monday in Delhi — early morning, finished hours before the sthapana window. Families who like to begin preparations at first light should note the day opens with Amrit choghadiya, 6:06 – 7:39 AM, ending exactly as Rahu Kaal begins: shopping, mandap setup and cooking fit the early window; the installation itself waits for midday.
Good windows after the sthapana, for visiting hours and the evening aarti:
- Chara: 1:49 – 3:21 PM and Laabha: 3:21 – 4:54 PM
- Amrit: 4:54 – 6:26 PM, closing at sunset
- After dark, Laabha again 10:49 PM – 12:16 AM for late celebrations
Why the date can differ by a day across almanacs
The madhyahna rule reads the tithi against the middle of the local solar day, so a city far enough west — or an almanac computing tithi boundaries with different constants — can attach the festival to the adjacent date. 2026 is not a close call in Delhi (Chaturthi holds from 7:08 AM through midday comfortably), but the mechanism behind such splits is real and worth understanding: why panchang sites show different dates.
The ten days, briefly
Sthapana on the 14th opens the Ganeshotsav; daily aarti and modak offerings follow, with visarjan processions building through Anant Chaturdashi ten days on. The timing rules attach to the sthapana — the visarjan day’s own windows are on its panchang page when you need them.
Other cities
Every window above is Delhi’s (sunrise 6:06 AM, sunset 6:26 PM). Choghadiya, Rahu Kaal and Abhijit all shift with local sunrise — Mumbai’s madhyahna is not Delhi’s. Bela computes the full day for 50 cities: open your city and go to 14 September.
Every time here is computed by the Bela engine and quoted from the same data that renders the panchang pages — nothing is transcribed from another almanac. For a sthapana window screened against your own birth star, the Bela app adds Tara Bala and Chandra Bala on top of the universal rules.
