Puthandu, Tamil New Year

What is Puthandu?

Puthandu (புத்தாண்டு, literally "new year") is the first day of the Tamil calendar, the day Tamils everywhere mark the start of a new year, on Chithirai 1. It is a solar festival: fixed not by the phases of the Moon, but by the moment the Sun crosses into the sign Mesha (Aries) in the sidereal zodiac.

Across Tamil Nadu, Puducherry, Sri Lanka and the wider Tamil diaspora, the day opens with kanni, the sight one deliberately arranges to see on waking, followed by a visit to the temple, a festive meal, and the reading of the year's panchangam, the almanac that lays out the months, planetary positions and predictions for the year ahead.

Mesha Sankranti, the Sun's entry into Aries

Every Tamil month begins on the day the Sun enters a new zodiac sign, an event the calendar calls sankranti. Chithirai, the first month of the Tamil year, begins the moment the Sun enters Mesha, the sidereal sign roughly corresponding to Aries. That instant is called Mesha Sankranti, and Chithirai 1, Puthandu, is the day it falls on, following the same sunset rule that governs every Tamil month: if the entry happens before sunset, the month starts that day; if it happens after sunset, the month starts the next day.

Because the Tamil calendar uses the sidereal zodiac, anchored to the actual positions of the stars rather than the seasons, Mesha Sankranti falls roughly three weeks later than the Western, tropical "Sun enters Aries" moment used in Western astrology, which lands near the spring equinox in late March. The gap between the two, currently around 24°, is the ayanamsa, and it is why Puthandu falls in mid-April rather than in March.

Why the date is so stable

Puthandu is one of the most predictable dates on the Hindu festival calendar. Because it is set purely by the Sun's sidereal longitude, with no reference to the Moon, it falls on 14 April in the great majority of years and only occasionally slips to 15 April, never earlier, and never much later.

Puthandu, Ugadi and Gudi Padwa, one new year, two systems

North and central Indian states also mark a spring new year, known as Ugadi in Andhra Pradesh, Telangana and Karnataka, and as Gudi Padwa in Maharashtra and Goa. It is, however, an entirely different system: a lunisolar new year calculated from the first tithi (Pratipada) after the spring new moon in the month of Chaitra, not from the Sun's position.

The 60-year cycle and this year's name

Each Tamil year carries a name drawn from a cycle of 60 names called samvatsara, tied to Jupiter's roughly 12-year orbit (5 orbits make 60 years). The cycle runs from Pirapava to Akshaya and then repeats. The name for the year that begins at Puthandu is traditionally announced from the temple pulpit and printed in that year's panchangam.

Traditions of the day

The day's first ritual happens before anyone has left bed. The night before Puthandu, an elder in the household arranges a tray called kanni, "the first sight", filled with objects considered auspicious, and places it where family members will see it as the very first thing on waking, often led there with eyes still closed by another family member. Typical items include:

• A mirror, so the first thing seen is one's own face among auspicious things
• Gold or other jewellery, for prosperity
• Fresh flowers, especially the golden konrai (Indian laburnum), regarded as Puthandu's flower
• Fruits such as mango, banana and jackfruit
• Betel leaves and areca nut
• Coins or currency notes
• An image of a deity, often Krishna or Ganesha
• A lit oil lamp (kuthuvilakku), raw rice and a coconut

The idea is that a beautiful, prosperous first sight sets the tone for the whole year ahead. Later in the day, families eat mango pachadi, a dish that brings all six tastes together in one bowl.

Later in the day, temples hold panchangam vaasippu, a public reading of the new year's panchangam. A priest or scholar reads out the year's name, its governing attributions, and the varsha phalam, predictions for each zodiac sign for the months ahead. It is one of the day's oldest continuously observed traditions, tying the astronomical calculation described in this guide directly back to the community that uses it.

Puthandu around the world

Puthandu travels with the Tamil diaspora, and its core traditions stay remarkably intact wherever it is celebrated.

• Sri Lanka, Puthandu coincides with the Sinhala New Year (Aluth Avurudda). Tamil and Sinhalese communities often celebrate together, and the combined "Tamil and Sinhala New Year" is an official public holiday.
• Malaysia and Singapore, large Tamil communities mark the day with temple visits, kanni and cultural programmes, often folded into the season's wider public holidays.
• Mauritius, Réunion and South Africa, descendants of nineteenth-century Tamil indentured labourers keep the kanni and mango pachadi traditions alive, often through local Tamil-heritage associations.
• Western diaspora (UK, North America, Europe, Australia), associations and temples hold the religious observance on the date itself and often schedule the larger cultural celebration for the nearest weekend.

Puthandu is not Pongal

Puthandu is sometimes confused with Pongal, because both are solar festivals tied to sankranti, but they mark entirely different things and sit three months apart.
