In response, PMK founder S. Ramadoss said the naming day cannot be the birthday and logically only November 1 can be the Tamil Nadu day.
In a statement issued here, Stalin said it was on November 1, 1956 that states were bifurcated on linguistic basis and as a result, the then Madras Presidency was divided into Andhra Pradesh, Karnataka, and Kerala.
Noting that November 1 was announced as the Tamil Nadu Day by the then AIADMK government from 2019 onwards, he said that as per Tamil experts/organisations and others, November 1 can be termed as the remembrance day for state border struggle and only July 18 can be termed as Tamil Nadu Day.
It was on July 18, 1967, during the Chief Ministership of C.N. Annadurai, that a resolution was passed in the Assembly for renaming Madras Presidency to Tamil Nadu, he said.
On his part, Ramadoss said that it was 11 years after the states were reorganised, that a resolution for renaming the state was passed in the Assembly and it came into effect only on January 14, 1969.
Birthdays can be celebrated only on the date of birth and not on the naming day or on the day on which a name was proposed, he said.
He said that it is 66 years since Tamil Nadu state was reorganised, 52 years since it was renamed, and 54 years since the name Tamil Nadu was proposed, and there will be confusion if a question on Tamil Nadu's age is asked.
Ramadoss said all the other states that were carved out of Tamil Nadu are celebrating November 1 as their birthday.
He also pointed out that Stalin had extended his greetings on November 1, 2019 when the AIADMK government decided to celebrate that day as Tamil Nadu Day.
It was also a DMK government led by M. Karunanidhi declared January 14 as the Tamil New Year Day in 2008.
Traditionally the Tamil New Year was celebrated on the first day of Tamil month 'Chithirai' (April 14) in Tamil Nadu, Puducherry and in countries like Sri Lanka, Malaysia, Singapore, Reunion, Mauritius and other countries with a Tamil diaspora.
When the AIADMK led by J.Jayalalithaa came back to power, the Tamil New Year celebration date was reverted to April 14.
