Understanding the Tamil Solar Calendar & Thiruvalluvar Aandu

The Tamil Calendar (தமிழ் நாட்காட்டி) is an ancient sidereal solar calendar followed across Tamil Nadu, Puducherry, Sri Lanka, Malaysia, Singapore, and the global Tamil diaspora. Commencing on the first day of Chithirai (Chithirai Puthandu, typically April 14), this calendar is synchronized with the Sun's transit into the first constellation of the sidereal zodiac (Mesha Sankranti).

The Thiruvalluvar Aandu (Epoch: 31 BCE)

In addition to the traditional 60-year cyclical names, the Government of Tamil Nadu officially recognizes the Thiruvalluvar Aandu (திருவள்ளுவர் ஆண்டு), founded in honor of the revered poet-philosopher Thiruvalluvar, author of the sacred Tirukkuṟaḷ. Based on archaeological and linguistic research led by Tamil scholars (including Maraimalai Adigal), the epoch of Thiruvalluvar was standardized to 31 BCE. The formula to calculate the Thiruvalluvar year is:

Thiruvalluvar Year = Gregorian Year + 31 (from Thai Pongal / mid-January)
The 60 Tamil Years (அறுபது தமிழ் வருடங்கள்)

Like the Sanskrit Barhaspatya Mana, the Tamil calendar organizes time into repeating 60-year cycles corresponding to five complete revolutions of Jupiter. In Tamil literature (such as the *Tholkappiyam* and Sangam texts), each of these 60 years carries distinctive societal, meteorological, and economic prognostications, beginning with Prabhava (பிரபவ) and culminating in Akshaya (அட்சய).

Semi-Technical Mechanics: The Six Seasons (Aru Paruvangal)

In classical Tamil Sangam literature, the year is systematically divided into six two-month seasons (Aru Paruvangal): Ilavenil (Early Summer: Chithirai-Vaikasi), Mudhuvenil (Peak Summer: Aani-Aadi), Kar (Monsoon: Aavani-Purattasi), Koothir (Autumn: Aippasi-Karthigai), Munpani (Early Dew/Winter: Margazhi-Thai), and Pinpani (Late Dew/Spring: Maasi-Panguni). Each season dictates specific temple pooja protocols, agricultural sowing, and classical music ragas performed in temples across Tamil Nadu.
