Chainpur observes Ganesh Chaturthi on Monday, 14 September 2026, along with the rest of Bihar.
The principal temple recorded for Marwan mandal is Thaneshwar Asthan Mandir. No temple of this dedication is on record within Chainpur itself.
The idol is kept for one and a half, three, five, seven days or until Anant Chaturdashi — it is a family custom rather than a rule, and community mandapams usually keep it longest.
| Kept for | Immersion | |
|---|---|---|
| One and a half days | Tue, 15 Septembertoday | |
| Three days | Thu, 17 September | |
| Five days | Sat, 19 September | |
| Seven days | Mon, 21 September | |
| Anant Chaturdashi | Wed, 23 September | The day most community mandapams immerse |
Many gram panchayats and municipalities set aside a pond or a marked stretch of tank for immersion. Ask at the panchayat office — it changes year to year, and a drinking-water tank or a farm pond is not an alternative.
A clay idol breaks down in water within hours. Plaster of Paris does not, and the paints carry heavy metals, so idols accumulate in tanks and rivers after immersion. Pollution control boards in most states now ask for clay for exactly this reason.
Immersion points get crowded and the bank is slippery after the monsoon. Children go into the water at these gatherings every year. Keep one person watching the water rather than the procession.
Thermocol, plastic sheeting, cloth and metal ornaments do not belong in the tank even when the idol itself is clay. Most organised immersion points now have a collection bin at the bank for them.
