Ganesh Chaturthi 2026: the madhyahna sthapana window, city by city
Most guides print one all-India sthapana time and move on. The murti has to go up in madhyahna, the midday window, because that is when Ganesha himself is held to have been born, and midday does not fall at the same clock time in Kolkata as it does in Ahmedabad. Here is the real window for sixteen Indian cities and six cities abroad, plus the reason a calendar in your hand might say the 15th while this page says the 14th.

Open five different Ganesh Chaturthi guides this week and you will likely find five different sthapana times, all confidently printed, all wrong the moment you are not standing in the one city each guide had in mind. The murti has to go up in madhyahna, the middle stretch of the day between sunrise and sunset, and midday in Kolkata is not midday in Ahmedabad. An all-India time that is right for Delhi can be off by more than an hour once you are further east or further west, which is not a rounding error when the whole point of the window is that it has to hold Ganesha's own birth hour.
This page gives the real madhyahna window for sixteen Indian cities and six cities abroad on Monday, 14 September 2026, computed for each city's own coordinates rather than borrowed from one reference point and stretched across the country. It also addresses something a careful reader deserves to have explained rather than papered over: a plain sunrise-based calendar can hand you 15 September for this same festival, and the two dates are not a case of one source being right and the other being sloppy. They are reading the day by two different classical rules, and this festival has a specific rule of its own.
Why madhyahna, and not sunrise
Most festival dates and most puja timings in the Vedic calendar are pinned to sunrise. The day itself is defined by which tithi, which lunar day, is running when the sun comes up, and a great many rituals simply take the morning as their working hour because morning is when a household's day begins.
Ganesh Chaturthi's sthapana does not follow that default, and the reason is specific rather than a matter of convenience. Ganesha is held to have been born at midday on Bhadrapada Shukla Chaturthi, so the murti's installation is timed to fall in madhyahna, the third of the five equal divisions the daylight hours are classically split into, running roughly from mid-morning to early afternoon. The installation is not simply "a puja that happens on the fourth day." It is a re-enactment of an arrival, and the hour it re-enacts has to match the hour of the arrival itself. That is the entire reason this festival breaks from the sunrise default that governs most of the calendar around it, and it is why an early-morning sthapana, however easier it might be to arrange around a workday, is not doing what the ritual actually asks for.
Madhyahna itself is not a fixed clock duration. It is defined as a fraction of that day's own daylight, sunrise to sunset split into five equal parts, so its length and its clock position shift with the season and with the city. On these dates it runs close to two and a half hours in most of the cities below, which is where the familiar rough figure people quote comes from, but the exact minutes it opens and closes are a function of each city's own sunrise and sunset, not a number that travels.
Why some calendars say the 15th
Bhadrapada Shukla Chaturthi, the tithi this whole festival is named for, begins at 14 September 07:07 IST, as a single global instant. That instant does not change depending on where you are standing, only the local clock reading of it does.
Here is where the two readings diverge. A sunrise-based assignment asks: on which day is chaturthi the tithi running when the sun comes up? On the morning of 14 September, the tithi still in force at sunrise everywhere in India is tritiya, the third lunar day, since chaturthi does not begin until 07:07, after every Indian city's sunrise has already happened that morning. A mechanical sunrise reading therefore does not find chaturthi at dawn until the following morning, and lands the festival on 15 September instead.
The classical rule this festival actually follows never asked that question. It asks whether chaturthi is running during madhyahna, because madhyahna is the hour the whole installation is built around. Chaturthi begins at 07:07 IST on the 14th, which is hours before the earliest madhyahna window on this list even opens, so chaturthi tithi is comfortably in force through every city's midday window that same day. The mainstream all-India almanac follows this madhyahna-based rule for exactly this festival, which is why 14 September is the date it publishes, and why it is the date used throughout this page. A calendar app that quietly defaults every festival to a sunrise reading is not wrong about what a sunrise reading gives. It has simply applied the wrong rule to this particular festival, one that was never a sunrise festival to begin with.
The Indian cities, in IST
Every sunrise, sunset and madhyahna window below is computed for that city's own coordinates on sidereal Lahiri, not derived from a single reference city and shifted by a flat offset.
| City | Sunrise | Sunset | Madhyahna (sthapana window) |
|---|---|---|---|
| Delhi | 06:06 | 18:27 | 11:03 to 13:31 |
| Mumbai | 06:26 | 18:41 | 11:20 to 13:47 |
| Kolkata | 05:23 | 17:40 | 10:18 to 12:45 |
| Chennai | 05:58 | 18:10 | 10:51 to 13:17 |
| Bengaluru | 06:09 | 18:20 | 11:02 to 13:28 |
| Hyderabad | 06:04 | 18:18 | 10:58 to 13:24 |
| Pune | 06:23 | 18:37 | 11:16 to 13:43 |
| Ahmedabad | 06:26 | 18:43 | 11:21 to 13:48 |
| Jaipur | 06:12 | 18:31 | 11:08 to 13:36 |
| Lucknow | 05:52 | 18:11 | 10:47 to 13:15 |
| Patna | 05:35 | 17:54 | 10:31 to 12:58 |
| Varanasi | 05:44 | 18:02 | 10:39 to 13:07 |
| Chandigarh | 06:07 | 18:29 | 11:04 to 13:32 |
| Bhopal | 06:07 | 18:24 | 11:02 to 13:29 |
| Indore | 06:13 | 18:30 | 11:08 to 13:35 |
| Nagpur | 06:01 | 18:16 | 10:55 to 13:22 |
Notice how far apart Kolkata and Ahmedabad sit, 10:18 against 11:21 at the start of the window, over an hour. A time copied from one end of the country to the other is not close enough to be a reasonable approximation. It can put a household outside its own madhyahna window entirely.
Cities abroad, in local time
For readers keeping the festival outside India, every window below is already converted to that city's own local time and its own local sunrise and sunset. Every one of these six cities is in the same tithi, shukla chaturthi, at its local madhyahna window as India is at hers, so there is no date confusion of the kind that some later festivals in the 2026 season do carry across time zones.
| City | Zone | Sunrise | Sunset | Madhyahna (sthapana window) |
|---|---|---|---|---|
| Dubai | GST | 06:05 | 18:23 | 11:00 to 13:28 |
| London | BST | 06:35 | 19:16 | 11:39 to 14:11 |
| New York | EDT | 06:36 | 19:05 | 11:36 to 14:06 |
| Singapore | SGT | 06:57 | 19:03 | 11:47 to 14:12 |
| Sydney | AEST | 05:57 | 17:44 | 10:40 to 13:01 |
| Toronto | EDT | 06:57 | 19:28 | 11:57 to 14:27 |
Using the window
Aim to begin the sthapana, carrying the murti to its platform and starting the Pranapratishtha invocation, once your city's window has opened, and to have the installation and the first aarti done before it closes. The window is roughly two and a half hours in most of these cities, which is enough time for the idol to arrive, the platform to be readied, and the family to gather without needing to treat the opening minute as a hard deadline. What matters is staying inside the span rather than starting the ritual hours before it opens or well after it has shut.
The installation steps themselves, the platform, the kalash, the Pranapratishtha mantra, and what to do across the ten days that follow, are laid out in full in Ganesh Chaturthi: the 10-day household pooja, decoded day by day. This page is only the dated part, the window itself, so that piece is the one to open next once you know when to begin.
The festival most households keep for ten days closes on Anant Chaturdashi, 25 September 2026, with the visarjan. That closing rite, the Anant Vrat, the fourteen knots tied on the wrist, and the immersion itself, runs on its own separate timing and is covered in Anant Chaturdashi: the Anant Vrat, the fourteen knots, and Ganesh Visarjan.
If your own birth chart raises a question here, whether a particular day inside this window suits you personally, or what a fresh start under Ganesha's blessing means for what your chart is currently showing, Ask Acharya takes that question in plain language, in your own language, and it is free. A free kundali is the place to start if you want to see your own chart before asking.
Frequently asked
Common questions
Why is the sthapana done at midday instead of at sunrise, which is when most other pujas start?+
Because the tradition ties this specific installation to the moment of Ganesha's own birth, which is held to have happened at midday on Bhadrapada Shukla Chaturthi, not at dawn. A puja that is opening a new venture or beginning a ritual cycle very often does want the sunrise or early-morning hours. This one is re-enacting an arrival, and the hour has to match the hour of the arrival it is re-enacting. That is why madhyahna, the middle fifth of the day between sunrise and sunset, is the window classical practice actually asks for here, and why an early-morning sthapana, however convenient, is not doing what the ritual is built to do.
My phone calendar says Ganesh Chaturthi is on 15 September, not the 14th. Which one is right?+
Both readings are internally correct, they are just answering different questions. A tithi begins and ends at a fixed instant everywhere in the world; on 2026's chaturthi, that instant is 14 September 07:07 IST, well after sunrise has already happened in every Indian city that morning. A calendar that assigns a festival to whichever day chaturthi is running at dawn will not find chaturthi at dawn on the 14th, since tritiya is still in force then, and lands on the 15th instead, the next sunrise chaturthi actually reaches. But the classical rule for this specific festival was never sunrise. It is madhyahna, and chaturthi tithi is running through every city's midday window on the 14th, comfortably, since it begins hours before the earliest of those windows opens. The mainstream all-India almanac follows that madhyahna rule and keeps the 14th, which is why this page does too. Neither app is broken. They are using two different classical rules for picking the day, and this festival's own rule is the midday one.
What if I genuinely cannot do the sthapana during the exact madhyahna window, say I am at work?+
Households manage this constantly, and the practical answer most priests give is to aim for as close to the window as the day allows, rather than treating the exact minute as pass or fail. If work keeps you out past the window's close, doing the installation in the evening rather than skipping the day is the accepted fallback in most households, and some families deliberately choose a Sunday or a day when someone is home to do the sthapana properly inside the window itself, even if that means the idol arrives home a day before the actual installation. What matters more than hitting the window to the minute is that the day itself, 14 September, is the correct one, and that the installation is not pushed to the 15th on the mistaken belief that a sunrise-based calendar app has corrected an error.
Does the window really change by city, or is a few minutes' difference not worth tracking?+
It changes by more than a few minutes across the country. Kolkata's madhyahna on this date runs from 10:18 to 12:45, while Ahmedabad's runs from 11:21 to 13:48, over an hour later at both ends, because sunrise and sunset themselves are more than an hour apart between the two cities on the same date. A family that copies a Delhi time onto a Chennai household, or a Mumbai time onto a Kolkata one, is not off by a rounding error. They could be starting the sthapana before madhyahna has even begun, or well after it has closed. City-specific timing is not a nicety here, it is the only way the window means what it is supposed to mean.
When does the festival end, and is the visarjan timed the same way?+
The ten-day observance most households keep, and the full Maharashtra tradition, closes on Anant Chaturdashi, 25 September 2026, with the visarjan, the immersion that sends the murti off. That closing day runs on its own classical rule, tied to sunrise rather than to midday, which is a separate calculation from the one this page covers. The day-by-day pooja between installation and immersion, what to offer and when, is covered in [Ganesh Chaturthi: the 10-day household pooja, decoded day by day](/blog/ganesh-chaturthi-10-day-pooja-vidhi), and the closing rite itself, the Anant Vrat and the fourteen knots along with the visarjan, is covered in [Anant Chaturdashi: the Anant Vrat, the fourteen knots, and Ganesh Visarjan](/blog/anant-chaturdashi-vishnu-anant-vrat-ganesh-visarjan).
I live outside India. Does the date or the window change for me?+
The date does not change, and neither does which tithi is running. Bhadrapada Shukla Chaturthi is the same global instant everywhere, so Dubai, London, New York, Singapore, Sydney and Toronto are all in the same tithi at their own local madhyahna windows as India is at hers on 14 September. What changes is only the clock reading of the window itself, since each city's own sunrise and sunset set where its midday falls. A family in New York installing at the New York madhyahna window and a family in Chandigarh installing at the Chandigarh madhyahna window are doing the same ritual, on the same day, each correctly reading local midday rather than importing a foreign clock time.
