Tamil literary and historical evidence
The Tamil calendar is based on the signs of the zodiac. The early Tamil literary work,
· The Nedunalvaadai is dated to between the years 100 and 300 of the common-era (CE). This was the Sangam era that represented the earliest outpourings of Tamil literature that survived the centuries. The poet Nakkirar authored the Nedunalvaadai. Lines 160 to 162 of the poem describe the movement of the sun through the 12 signs of the zodiac starting with Medam or Mesha .
· Koodaloor Kilar, a contemporary of Nakkirar, in the 229th Poem of the Puranaanooru also refers to the 12 signs of the zodiac that begin with Medam in April.
· The Tolkaapiyam is the oldest surviving Tamil grammar. This is dated by several to 400 CE. The Tolkaapiyam divides the year into six seasons where Chitterai in April marks the start of the Ila-venil season or summer. Thai in January conversely does not commence any season.
· The Silappadikaram is a Tamil epic that is dated by some to 500 CE. Canto 26 of the text once again refers to the 12 signs of the zodiac with the sun commencing its journey through the heavens in the sign of Medam in April. Canto 5 of the Silappadikaram describes the foremost festival in the Chola country that was celebrated in Chitterai.
· The Manimekalai, another classical epic in the Tamil language refers to the Tamil solar calendar as we know it today.
· The early medieval Urai-aasiriyar or commentator, Adiyaar-ku-nalaar mentions the 12 months of the Tamil calendar with particular reference to Chitterai.
Tamil Hindu tradition influenced Cambodia, Indonesia, Thailand, Burma and Laos between 400 CE and 1200 CE. This coincided with the adoption of the Pallava grantha script, the centralization of royal authority and the adoption of the Tamil new year in these countries. This explains the celebration of the new year in mid-April in Burma, Cambodia, Thailand and Laos. There are inscriptional references in Pagan, Burma to Vaishnavite courtiers from the Chola country, known in Burmese as the Sankran Bumnah, who were tasked with calculating the start of the new year in mid-April. These inscriptions can be dated to circa 1000 CE. Similar inscriptions in Sukhothai, Thailand refer to South Indian keepers of the calendar in the 14th century CE.
The observance of the traditional Tamil new year in April continued in the days of the 10th century Chola empire as witnessed in Saivite Tamil texts and inscriptions and in the days of the Jaffna Kingdom. It was hallowed by tradition. Kandyan royalty intermarried with aristocratic families from Thanjavur which led to the Nayakar dynasty ruling the Kandyan kingdom from 1739 to 1815 CE.
Robert Knox documents the celebration of the April new year in the Kandyan kingdom during the Dutch era. He had used the Julian calendar then prevalent in England and therefore described the event in late March, April in today’s reckoning.
The 1920s: A Time of Ferment
Events in the 1920s provide the backdrop to Karunanidhi’s efforts in 2008 to shift the date of the Tamil New Year. The Indian National Congress (INC) was becoming a mass-based freedom movement in the 1920s. It was making deep inroads into the Madras Presidency as witnessed in the efforts of anti-colonial freedom fighters such as V.O Chidambaram Pillai, affectionately remembered as Kapal-otiya Tamizhan, Subrahmanya Bharati and Subramanian Sivam. The leadership of the INC in Madras however was Tamil Brahmin dominated. The Vellalar or farmer caste and the Telugu Brahmin were under-represented. The colonial authorities leveraged the Vellalar-Chettiar-led Justice Party to counter the influence of the INC. The Justice Party backed the continuation of British rule.
Maraimalai Adigal, a Saivite Vellalar, provided the religious underpinnings of this movement. Amongst other things, he called for a change in the date of the Tamil new year from Chitterai in April to Thai Pongal in January in the 1920s. He dismissed the April new year as a Brahmin event while Pongal was then a pre-eminently Vellalar festival. His suggestion was not accepted by the population at large. It bears mention, however, that seven other Saivite Vellalar activists including Navalar Somasundara Bharatiyar, K. Subramaniapillai, Kalyanasundera Mudaliyar and Sachidanandapillai supported his efforts. Maraimalai Adigal claimed that Pongal was uniquely Tamil, an assertion that was incorrect as demonstrated below. Critics charge that the real motive was to align the Tamil calendar with the English year that began in January. Regardless, the proposal was forgotten for the next 80 years.
The Karunanidhi Era
Much later, in 2008 the Tamil Maiyam led by Father Jagath Gasper Raj revived the call for a change in the date of the Tamil new year, a suggestion accepted by Karunanidhi, the Chief Minister of Tamil Nadu. While all political parties in Tamil Nadu initially supported the move, the All India Anna Dravida Munnetra Kazhagam, led by Jayalalithaa, and the pro-LTTE Marumalarchi Dravida Munnetra Kazhagam, led by Vaiko, quickly opposed Karunanidhi’s proposed change in the date of the new year. The Union Territory of Pondicherry did not accept the change either. Popular sentiment ignored efforts of Karunanidhi to move the Tamil New Year to January. A case was filed by a group purportedly including Dalit, Thevar, Nadar, Vanniyar and Chettiar caste members, in the Madurai bench of the Tamil Nadu high court challenging Karunanidhi on this count. The High Court, after much delay, is likely to hear the case in April 2011.
Karunanidhi, in an effort to accommodate public opinion in Tamil Nadu, conceded the celebration of the April new year with a new term called Chithirai Tiru-naal, the holy day of Chithirai. The day remained a public holiday in Tamil Nadu, albeit purportedly to commemorate the birthday of the veteran Dalit leader Dr. B.R. Ambedkar.
