Sorry, I can only provide information that is clearly established within Jain tradition.

For Latki Poonam as per Tapa Gachchha, the date depends on the specific Jain Panchang followed by the Tapa Gachchha sangh, and it may vary by place, sunrise/tithi calculation, and local sangh tradition.

Please confirm from your local Tapa Gachchha Jain Sangh / Upashray / Jain Panchang for the exact date.
