Ganesh Chaturthi (Vinayaka Chaturthi) celebrates the birth of Lord Ganesha, the remover of obstacles and the deity of wisdom and auspicious beginnings. The festival is observed on Bhadrapada Shukla Chaturthi, the fourth lunar day of the waxing moon, and is determined by the presence of Chaturthi Tithi during Madhyahna Kala. It is celebrated worldwide with clay icons, Vedic worship, Modaka offerings, and concludes with Visarjan on Ananta Chaturdashi.
Significance of Ganesh Chaturthi
वक्रतुण्ड महाकाय कोटिसूर्यसमप्रभ।
निर्विघ्नं कुरु मे देव सर्वकार्येषु सर्वदा॥
"O Lord with the curved trunk, immense form, and the radiance of ten million suns! Please make all my endeavors free of obstacles, always."
The Sacred Calendar: Understanding Chaturthi
- Vinayaka Chaturthi — the 4th lunar day of the waxing moon phase (Shukla Paksha), occurring every month.
- Sankashti / Sankatahara Chaturthi — the 4th lunar day of the waning moon phase (Krishna Paksha), dedicated to removing afflictions.
While monthly Chaturthis are observed throughout the year, the Bhadrapada Shukla Chaturthi (August/September) is celebrated grandly worldwide as Ganesh Chaturthi. Another significant observance is Varada Chaturthi / Ganesh Jayanti, celebrated in Magha (usually January/February).
How Is Ganesh Chaturthi's Date Determined?
Ganesh Chaturthi is not determined solely by the sunrise tithi. According to the Ganesha Purana, Lord Ganesha manifested during Madhyahna Kala (the midday period). The festival is observed on the day Chaturthi Tithi prevails during Madhyahna — even if sunrise belongs to Tritiya.
Why is the festival celebrated on Chaturthi even if Tritiya is present at sunrise?

Why Is Ganesh Chaturthi on a Different Date in Different Cities?
Sunrise differs by city → Madhyahna differs by city → Chaturthi begins at a different local moment → the festival follows Madhyahna → therefore the observed date can differ. Tithi boundaries are tied to an exact moment in time, not a calendar day.

Frequently Asked Questions
What is Ganesh Chaturthi?
Ganesh Chaturthi (Vinayaka Chaturthi) is the festival celebrating the birth of Lord Ganesha, observed on Bhadrapada Shukla Chaturthi -- the fourth lunar day of the waxing moon in the month of Bhadrapada.
When is Ganesh Chaturthi?
The date shifts each year with the lunar calendar and can vary by city, since it is determined by when Chaturthi tithi prevails during Madhyahna locally. See your city's specific page for the confirmed local date.
Why does Ganesh Chaturthi sometimes fall on two different dates in different cities?
Because Madhyahna is computed from each city's own sunrise and sunset, the same tithi can be active during Madhyahna in one city but not another -- occasionally shifting the observed date by a day between cities.
What is Madhyahna Kala?
Madhyahna is the middle fifth of the daylight period between sunrise and sunset -- roughly the midday window. Ganesh Chaturthi's date is tied to whichever day Chaturthi tithi is active during this specific window.
What is Vinayaka Chaturthi?
Vinayaka Chaturthi is the monthly occurrence of the 4th lunar day during the waxing moon (Shukla Paksha). The Bhadrapada occurrence specifically is celebrated as the major Ganesh Chaturthi festival.
Can Ganesh Chaturthi occur when Tritiya is present at sunrise?
Yes -- since the determining factor is Madhyahna, not sunrise, the day can begin under Tritiya and still be the correct day for Ganesh Chaturthi, as long as Chaturthi has begun in time to cover the Madhyahna window.
Why are clay icons preferred?
The clay icon represents Prithvi Tattva (the Earth element), reinforcing a connection to nature and mindful use of natural materials, in contrast to icons made from non-biodegradable materials.
When is Visarjan performed?
Visarjan is performed on Anant Chaturdashi, at the conclusion of the up-to-10-day festival, symbolizing the return of the earth-element icon back to nature.
Why is Ganesh called Vighnaharta?
Vighnaharta means 'remover of obstacles' -- reflected directly in the shloka above, which asks Ganesha to make all endeavors free of obstacles.
