Puthandu

Significance and story

Puthandu is the Tamil new year, observed in Tamil Nadu on the day the Sun enters Mesha, the first sign of the zodiac. In the Tamil calendar this day is Chithirai 1 — the first day of the month of Chithirai. The name itself carries the sense of a new year: puthu for new, andu for year.

Because the observance is tied to the solar ingress into Mesha rather than to a lunar phase, Puthandu marks a fresh solar cycle. It is a day of beginning — of turning the page, settling accounts with the past year, and starting the new one with a clean and auspicious frame of mind. Households greet one another, elders are sought for blessings, and the day is treated as one on which whatever is begun should be begun well.

The brief for this page records no single presiding deity for Puthandu. The observance belongs to the household and the community as much as to any one shrine, and it is kept across Tamil Nadu by families of differing sectarian allegiance. Readers who wish to know which form of the divine is traditionally invoked in their own family or kula should ask their elders or a qualified jyotishi rather than rely on a general page such as this one.

How the date is fixed

The date of Puthandu is not fixed in the Gregorian calendar. It is determined each year from the panchang, by the moment the Sun enters Mesha — the solar ingress known in jyotish as Mesha Sankranti. The Tamil month of Chithirai begins at that moment, and Puthandu is observed as Chithirai 1.

Two consequences follow from this, and both are worth understanding.

• Because the Sun's entry into a sign is a single astronomical instant, the Gregorian date on which Puthandu falls can move by a day from year to year.
• Because the observance is anchored to a solar event rather than a lunar tithi, it is not subject to the amanta and purnimanta difference that shifts many lunar festivals. The amanta and purnimanta reckonings diverge over the lunar month; a solar ingress does not divide in the same way.

Even so, the exact Gregorian dates are computed each year from the panchang and are listed on this page from the database. The dates shown here are calculated for New Delhi sunrise with Lahiri ayanamsha. Readers in other cities, and in the diaspora, may find that local panchangs give a marginally different civil date for the observance, and that is expected — the underlying sankranti moment is the same, but the local sunrise and the local convention for assigning a festival day can differ.

Where traditions differ on how a solar festival day is assigned, this page does not choose one convention over another. It states the principle — Sun enters Mesha, Chithirai 1 — and leaves the local application to the reader's own panchang and family practice.

Puja vidhi

The brief for this page records the observance simply as the Tamil new year, and does not prescribe a single ritual sequence. What follows is therefore general, and families will have their own inherited way of keeping the day.

Puthandu is characteristically a household observance. The day is begun early, with a bath and clean clothes, and the home is prepared beforehand so that the new year opens in an ordered and welcoming space. A lamp is lit, and the family deity is worshipped in whatever manner the household follows. Elders are greeted and their blessings sought — in many homes this is the first act of the new year, and it is treated as the most important.

Because the day is a solar beginning, the Sun is naturally at the centre of the observance, and many families include a simple offering to the Sun at sunrise. Beyond this, the details vary widely by family and by region, and no single vidhi can be called the Puthandu vidhi. Readers who want a procedure matched to their own sampradaya should consult their family tradition, their local priest, or a qualified jyotishi.

Regional variations

Puthandu is observed in Tamil Nadu. The brief for this page places the observance there, and does not extend it further.

It is worth noting, without conflating the observances, that other regions of India keep their own new year days, and these do not always fall on the same date. Some are solar and some are lunar; some are tied to the same Mesha Sankranti and some are not. Where a reader has family in more than one region, it is common to find two new year days being kept in the same extended household. This page does not attempt to reconcile them. Each has its own basis in the panchang, and each is observed according to its own regional and family tradition.

Within Tamil Nadu itself, customs differ from household to household and from community to community. The page states the shared principle — Sun enters Mesha, Chithirai 1 — and leaves the particulars to the reader's own tradition.

What to avoid

• Do not treat the dates on this page as universal. They are computed for New Delhi sunrise with Lahiri ayanamsha, and local panchangs may assign the observance to a neighbouring civil date.
• Do not read this page as a personal prediction. Puthandu is a calendar observance, not a forecast for any individual's year. For matters concerning your own chart, consult a qualified jyotishi.
• Do not assume a single ritual form. The brief records no presiding deity and no fixed vidhi for Puthandu; family and regional tradition govern.
• Do not confuse Puthandu with the new year observances of other regions, which may rest on a different panchang basis entirely.
• Do not expect this page to settle questions of health, money, marriage or legal matters. It does not address them, and no festival date should be used as a substitute for qualified advice.
