We did not go because of excessive crowds and photo-taking restrictions. But this is their event schedule from the patrikai:
“On the upcoming Monday, 14.09.2026, on the occasion of the Sri Vinayaka Chaturthi festival, the temple doors will open at 4:00 AM in the early morning. On behalf of the temple administration, special Abhishekam (ritual bathing), Dhoopa Deepa (incense and lamp offering), Neivethiyam (food offering), and Deeparadhanai (worship with lit lamps) will be performed for Sri Manakkula Vinayaka. After performing the Deeparadhanai (light offering ritual), "Moolavar Sri Manakkula Vinayaka" will bless devotees adorned in a gold armour (Thanga Kavasam).”
