When you think of Ganesh Chaturthi, you probably picture colourful idols of Lord Ganesha, sweets, and prayers. But in Mithila—a cultural region that covers parts of Bihar in India and Nepal—Ganesh Chaturthi has a very different flavour. Here, people celebrate Chaurchan, a festival dedicated not only to Ganesha but also to the moon (Chandra).
This may sound unusual because, according to most Hindu traditions, people avoid looking at the moon on Ganesh Chaturthi. Why? Because of a curse by Lord Ganesha. But Mithila has its own story, its own belief, and its own pride.
Let’s explore this fascinating tradition.
What is Chaurchan?

Chaurchan, also called Charchanna Pabni, Chauthichanda (चौठीचंदा) or Chaurchan Puja, is a special festival of Mithila. Married women mainly observe it for the welfare of their families. The festival involves worshipping both Lord Ganesha and the Moon God.
- Celebrated on Ganesh Chaturthi evening
- Includes moonrise prayers, family gatherings, and community songs
- Highlights Mithila’s distinct identity within Indian culture
The Story Behind Chaurchan
The Royal Connection
Chaurchan became popular during the 16th century under King Hemangad Thakur. While imprisoned by the Mughal emperor, he wrote a book on astronomy called Grahan Mala. His scholarship impressed Emperor Akbar, who released Mithila from taxes.
On hearing this, Queen Hemalata declared:
“Today, the moon of Mithila has become free from stigma; we will see and worship it.”
This moment gave birth to Chaurchan as a proud celebration of Mithila’s freedom and culture.
Why Do People Worship the Moon on Ganesh Chaturthi?
In most of India, people avoid the moon on this day. The reason comes from a legend:
- The Moon God once mocked Lord Ganesha.
- Ganesha cursed him: anyone who sees the moon on Ganesh Chaturthi will face false accusations (Mithya Dosha).
But Mithila believes differently. Here, people say moon worship actually removes negativity and brings blessings. It’s a powerful example of how traditions can vary, even within the same religion.
Rituals of Chaurchan
The celebration follows a simple yet beautiful sequence:

Morning Preparations
- Courtyards are cleaned with cow dung (a traditional disinfectant).
- Decorative rice patterns (gangoli) are drawn.
- Special prasad like kheer, puri, thekua, and maalpua is prepared.
Evening Puja
- Families gather in the courtyard.
- As the moon rises, people chant mantras such as:
“दधि-शंख-तुषाराभं, क्षीरोदार्णव-संभवम्।
नमामि शशिनं भक्त्या, शंभोर्मुकुट भूषणम्।।” - Offerings (arghya) of water, sweets, and curd are made to the moon.
Community Joy
- People sing folk songs and recite stories.
- Sharing prasad strengthens family and community bonds.
Chaurchan Puja Mantra
A special mantra is also recited at moonrise to protect from the curse of false blame (Mithya Dosha):
“सिंहः प्रसेनवमवधीत सिंहो जाम्बवताहतः ।
सुकुमारक मारो दीपस्तेह्राषव स्यमन्तकः ।”
Simple meaning:
- A lion killed Prasena.
- Jambavan killed that lion.
- Dear child, don’t cry. This is your Syamantaka jewel.
This verse is recited while offering arghya to the moon. It reminds devotees that faith and prayer can remove stigma and negativity.
