So, you’re looking at the calendar and wondering when is Ganesh puja this year. It's a bit of a trick question because the date shifts every single year on the Gregorian calendar. Unlike Christmas or even Halloween, the "rebirth" of the elephant-headed God depends entirely on the lunar cycle. Specifically, we're looking for the Bhadrapada Shukla Chaturthi.
In 2026, the main event—Ganesh Chaturthi—falls on Tuesday, September 15.
If you're planning a massive pandal or just a small "sthapana" at home, that’s the date to circle in red. But honestly, it’s not just about one day. The festival is a sprawling ten-day marathon of modaks, chanting, and high-energy music that wraps up with Anant Chaturdashi on September 25, 2026.
Why the Date Changes Every Year
The Hindu calendar is lunisolar. It tracks the moon's phases while occasionally syncing back up with the sun. This is why Ganesh Chaturthi can feel like it's "early" in August or "late" in September.
The puja begins on the fourth day (Chaturthi) of the waxing moon period in the month of Bhadrapada. Astronomically, this is when the moon is at a specific elongation from the sun. Vedic priests and various panchangs (almanacs) like the Drik Panchang or the Vishwavidyalaya Panchang calculate the exact "Tithi" or start time.
For 2026, the Chaturthi Tithi actually starts late on September 14 and ends on the evening of September 15. Because the sunrise (Udaya Tithi) on the 15th happens while the Chaturthi is active, that is the day designated for the festival.
The Best Time for the Sthapana (Puja Muhurat)
Timing is everything. You don't just plop the idol down whenever you feel like it. Well, you could, but if you’re following tradition, there’s a specific window called the Madhyahna Ganesha Puja Muhurat. This is considered the most auspicious time because Lord Ganesha is believed to have been born during the midday period.

For September 15, 2026, the prime window for the puja is generally between 11:03 AM and 1:32 PM.
That’s roughly two and a half hours to get everything right. If you miss that window, don't panic. Many people perform the puja during the Pratahkal (morning) or even later in the day if their local priest suggests a specific Choghadiya (auspicious time segment). But the midday slot is the gold standard.
Forget the Moon: The Curse of Mithya Dosha
Here is a weird detail a lot of people forget. There’s an old Puranic legend that says if you look at the moon on the night of Ganesh Chaturthi, you’ll be cursed with Mithya Dosha.
Basically, you’ll be falsely accused of stealing or some other crime.
Lord Krishna was famously accused of stealing the Syamantaka jewel because he caught a glimpse of the moon on this day. So, if you're wondering when is Ganesh puja so you can go out and celebrate, keep your eyes on the ground or the idol, not the sky. In 2026, the "forbidden" moon-sighting window is from roughly 9:15 AM to 9:05 PM on September 15th.
Regional Differences in Celebration
While the date remains the same across India, how people treat the timeline varies wildly.

In Maharashtra, especially Mumbai and Pune, the ten days are a massive public spectacle. You have the Lalbaugcha Raja, which attracts millions. Here, the "when" is less about a single day and more about the "Visarjan" (immersion) schedule. Some families keep the idol for one and a half days, others for five, seven, or the full ten.
In Karnataka and Andhra Pradesh, the festival is often called Vinayaka Chavithi. The focus is heavily on the "Gowri Habba," which happens exactly one day before Ganesh Chaturthi. So, for those in Bangalore or Mysore, the festivities actually start on September 14, 2026.
The Modak Factor
You can't talk about the timing of the puja without talking about the food prep. Since the puja happens at midday, the kitchen is usually a war zone by 8:00 AM.
The traditional "Ukadiche Modak" (steamed rice flour dumplings) take forever to make. If you’re hosting, your personal "when is Ganesh puja" timeline starts at least 48 hours earlier with the grating of fresh coconut and the soaking of rice.
Planning for 2026 and Beyond
If you are a corporate planner or someone who travels for the festival, knowing the date well in advance is a lifesaver. Flight prices to Mumbai or Hyderabad skyrocket in the weeks leading up to the 15th.
- 2026: September 15
- 2027: September 4
- 2028: August 23
Notice how it jumps around? That’s the lunar cycle at work.

Why the 2026 Date is Unique
September 15, 2026, falls on a Tuesday. In Hindu tradition, Tuesday (Mangalvar) is already a day dedicated to Lord Ganesha (and Hanuman). When Ganesh Chaturthi falls on a Tuesday, it is sometimes referred to as an exceptionally "Siddhivinayak" day, boosting the perceived spiritual "charge" of the prayers. It’s like a double dose of auspiciousness.
Practical Steps for Your 2026 Puja
If you're looking to observe the festival, don't wait until September 14 to figure things out.
- Book your idol early. Most eco-friendly clay (Shadu mati) artists take orders as early as May or June. By August, the best craftsmen are usually sold out.
- Verify the Visarjan spot. If you’re in a city like Mumbai, the municipal corporation (BMC) usually releases a list of artificial ponds. Check this a week before the 15th to avoid the chaos of the beaches.
- Check the Rahu Kaal. Even during the auspicious day, there are small windows called Rahu Kaal that many avoid for the actual installation. On Tuesday, September 15, this is usually between 3:00 PM and 4:30 PM. Aim to have your idol settled before this.
- Sourcing the 21 Herbs. Traditional puja requires 21 Patris (different types of leaves). Finding these in a concrete jungle is tough. Coordinate with a local florist or a specialized puja-kit vendor at least three days prior.
The most important part of the timing is your own intention. Whether you start at 11:03 AM sharp or find a moment of peace later in the afternoon, the festival is a reset button for the year. It’s about clearing obstacles. Knowing exactly when is Ganesh puja is just the first step in making sure you're ready when the "Vighnaharta" (remover of obstacles) arrives at your door.
Check your local temple’s specific Sankalpa time if you’re performing a public ceremony, as minor geographic shifts in longitude can move the "perfect" minute slightly forward or backward. But for 99% of us, the September 15 midday window is the time to celebrate.
Assemble your materials, get the steamed modaks ready, and make sure your 2026 calendar is marked correctly. Preparation beats stress every time during the festive season.
