The four days, before anything else

In 2026 the Saraswati sequence inside Navratri runs across four days. Saraswati Avahan — the invocation — falls on Saturday, October 17. Saraswati Puja falls on Sunday the 18th. Saraswati Balidan falls on Monday the 19th. Saraswati Visarjan falls on Tuesday, October 20, which is also Vijayadashami.

That is the answer, and for many readers it is the only thing needed. What follows is worth a few minutes because the reason those are the dates is not the reason most people assume, and knowing it is what lets you check any other year for yourself instead of trusting a listing.

The four rites are named in the panchang as a set. Avahan (आवाहन) is invitation or invocation — asking the deity to be present. Puja is the worship itself. Balidan (बलिदान) is the offering. Visarjan (विसर्जन) is the formal leave-taking, the release of the presence that was invited. The sequence has a shape: you call, you honour, you offer, you let go. It is the same grammar as Ganesh Chaturthi’s sthapana and visarjan, compressed into four days inside a larger festival.

Why this sequence answers to nakshatras, not tithis

Nearly every date in the Hindu calendar is fixed by the tithi — the lunar day, one thirtieth of the cycle from new moon to new moon, measured as the angle between the Moon and the Sun. Ghatasthapana is a tithi rite. Ashtami and Navami are tithis. Vijayadashami is a tithi. When someone asks what day a festival falls on, the answer almost always comes from that clock.

The Saraswati sequence uses the other one. A nakshatra is one of the twenty-seven lunar mansions — a fixed 13°20′ segment of the zodiac that the Moon moves through, named for the stars in it. It has nothing to do with the Sun’s position, so it drifts against the tithi completely. Saraswati Avahan is keyed to Mula, Puja to Purva Ashadha, Balidan to Uttara Ashadha and Visarjan to Shravana — four consecutive nakshatras, in order.

This is not an obscure technicality. It is the single fact that explains why the Saraswati dates in one household’s calendar can differ from the Durga Puja day-names in another’s, in the same week, without either being wrong. They are reading two different clocks that happen to run through the same nine nights. Our guide to how a muhurat is actually derived from the panchang works through both clocks in more detail if you want the mechanism rather than the dates.

One consequence is worth stating plainly: because a nakshatra averages a little over twenty-four hours — about twenty-four hours and seventeen minutes, the sidereal month divided by twenty-seven — it usually covers exactly one sunrise, but not always. In a year where one nakshatra spans two sunrises, another gets skipped entirely, and the four-day sequence compresses or doubles up. In 2026 the four run about twenty-seven hours each and take one sunrise cleanly across almost all of India — with one genuine exception in far-western Gujarat, worked through below. That is a fact about this year and this place, not a rule, and it is exactly the kind of thing worth checking on the live panchang rather than assuming.

The four and a half minutes that split Chennai from Kolkata

Here is the part no date listing will tell you, and it lands on the very first day of the sequence.

Saraswati Avahan is on Mula, which begins at 6:47:49 am IST on Friday the 16th and runs until 9:47 am on Saturday. Across almost all of India that means Saturday the 17th is the only sunrise in the whole festival on which Mula is the prevailing nakshatra — Friday’s sunrise comes a few minutes too early to catch it, and by Sunday the nakshatra has moved on. On Friday morning Delhi rises at 6:22, Mumbai at 6:32, Ahmedabad at 6:36 and Rajkot at 6:43 — all before Mula opens.

There is one region where that is not true, and it happens to be a Navratri heartland. Keep going west into Saurashtra and Kutch and sunrise slides past 6:47. Porbandar rises at 6:47:32 on Friday — seventeen seconds inside Jyeshtha, the nakshatra before Mula. Bhuj rises at 6:48:26, Okha at 6:50:15, Dwarka at 6:50:31, and the far tip of Kutch later still: for all of them Friday’s sunrise has already entered Mula. In those places Mula prevails at both sunrises, Friday and Saturday, and the first day of the Saraswati sequence is genuinely ambiguous — the one case this guide otherwise says 2026 does not have. If you are in Kutch or on the Dwarka peninsula, that is the day to check against your own sunrise rather than against a printed list.

Note that this is not a simple line of longitude. Bhuj sits slightly east of Porbandar and still rises later, because it is nearly two degrees further north and in mid-October the higher latitude rises later. Longitude gets you most of the way; latitude decides the last minute, which is exactly the margin in question here.

That is the nakshatra half, and outside Kutch it is uniform. The tithi half is not, and it splits the country far more finely. Saptami begins at 5:54 am IST on Saturday the 17th. Sunrise in Kolkata that morning is 5:33 — twenty-one minutes before Saptami opens, so Kolkata greets the day in Shashthi. Sunrise in Chennai is 5:59 — four and a half minutes after, so Chennai greets it in Saptami. Bengaluru and Hyderabad are at 6:09, Delhi at 6:22, Mumbai at 6:33: all comfortably inside Saptami.

So on the one morning that Saraswati is invited into the house, two families doing exactly the same thing at their own sunrise are standing in different lunar days. Nobody has made an error. The nakshatra agrees; the tithi does not; and the tithi is the clock the Durga Puja day-names run on. This is the mechanism behind the perennial confusion about which day is which during these nine nights — and it comes down, in 2026, to a margin of about four and a half minutes on the Coromandel coast.

A caution worth attaching: regional almanacs do not all assign a festival day by the tithi prevailing at sunrise. Some rites are fixed by the tithi prevailing at a particular part of the day instead — Vijayadashami is fixed by aparahna, the afternoon, which is why our Dussehra 2026 guide computes a different window from a sunrise one. The numbers above are the computed boundaries; how your own tradition assigns the day from them is a question for your family’s panchang, and a good one to bring to Purohit Ji with your city.

Golu, Bommai Kolu, Bombe Habba: what the steps are actually holding

In Tamil Nadu, Karnataka, Andhra Pradesh and Telangana, the nine nights are kept in a way that has no real equivalent elsewhere in the country: a household builds a tiered display of dolls and figures and keeps open house around it. It is called Golu or Bommai Kolu in Tamil, Gombe Habba or Bombe Habba in Kannada, and Bommala Koluvu in Telugu. The word behind the Tamil and Telugu names carries the sense of a court or a royal assembly — the goddess holding court, with the whole world arranged in front of her.

The display is built on steps, called padi, and the number of steps is traditionally an odd one — three, five, seven, nine or eleven, according to the household’s space and inheritance. The arrangement is not decorative filler; it is a cosmology laid out vertically. The uppermost steps carry deities. Below them come saints, teachers and the figures of devotional history. Below those, kings, courts and human authority. Lower still, ordinary human life — weddings, professions, musicians, a shopkeeper at his scales. At the very bottom, frequently, a chettiar shopfront, a park, animals, a village scene, and increasingly whatever the children of the house wanted to add.

That descent is the point. The display puts divinity at the top and does not stop until it has reached a toy cow, and the argument it is making — that the same order runs through all of it — is made by the arrangement rather than by anything anyone says out loud.

Two objects usually anchor it. A kalasham — a pot, often with a coconut and mango leaves — stands as the invited presence, the same grammar as the kalash of Ghatasthapana. And a pair of marapachi bommai, wooden dolls traditionally given to a bride for her new home, are placed as the household’s own founding pair; in many families they are the oldest things on the steps and are the reason the collection exists at all.

Around the display runs the part that is actually the festival: visiting. Neighbours, and especially women and children, are invited in; sundal — a different legume each day, boiled and tempered — is offered; and guests leave with tamboolam, the parting gift of betel leaves, areca nut, a coconut, fruit and often a small piece of cloth. In many households a girl or woman visitor is asked to sing before she leaves. On Vijayadashami the display comes down, and in a common practice one doll is laid on its side to sleep before the rest are packed away for the year.

Practices vary by family, community and state, and this is a description of the widely-kept shape rather than a rule anyone is failing. A household that keeps seven steps where its neighbour keeps nine, or that has never owned a marapachi pair, is not doing it wrong.

What each of the four days asks of you

The sequence is modest in what it actually requires, and it is worth separating what the tradition asks from what has accumulated around it.

On Avahan day, Saturday the 17th, what is invited is Saraswati’s presence into the objects of learning in the house. In practice this means the books, the instruments, the pens and the tools of study are gathered and placed together — on a clean cloth, before the image or the kalasham — and the invitation is made. From that moment they are not used. That restraint is the whole rite: the household stops studying, stops playing the instrument, stops writing, because what learning is done through has been given back for a few days.

On Puja day, Sunday the 18th, the gathered objects are worshipped where they lie. Offerings are simple and white or pale by preference — white flowers, and in many households sweet rice or a milk preparation. Nothing is taken up.

On Balidan day, Monday the 19th, the offering is made. The word carries the sense of a sacrifice given up, and in the great majority of households today that is a food offering and nothing else. This is the day when regional practice diverges most sharply from the panchang’s own listing, because in much of the south this same Monday is Maha Navami and carries Ayudha Puja instead — the worship of the tools of one’s trade, treated at length in our Ayudha Puja and Vidyarambham guide.

On Visarjan day, Tuesday the 20th, the presence is formally taken leave of and the books and instruments are picked up again. In many households the first thing done after they are taken up is a deliberate act of learning — a line written, a scale played, a page read — which is where this sequence meets Vidyarambham, the beginning of letters, kept on the same day in Kerala and elsewhere.

If you want the aarati sung to Saraswati during these days, the text with its meaning is in our Jai Saraswati Mata entry.

The other Saraswati Pujas, and why none of them contradicts this one

A reader who looks this up will meet at least three different answers to “when is Saraswati Puja”, and will usually be told that two of them are mistakes. They are not. They are different rites that share a name.

The nakshatra sequence described above — Avahan, Puja, Balidan, Visarjan across Mula to Shravana — is the panchang’s own listing, and it is what a north Indian almanac will print against these four days.

The Maha Navami rite kept in Tamil Nadu, Karnataka and the Telugu states places books and instruments for worship alongside the tools of trade on Navami itself. It shares its objects and much of its meaning with the sequence above, and it lands on the same weekend, but it is timed by the tithi rather than the nakshatra and it belongs to the Ayudha Puja complex.

The Kerala sequence is different again: the books are laid down on Ashtami evening in Puja Vaipu, left unread through Navami, and taken up on Vijayadashami morning in Puja Eduppu, the same hour a child is started on their letters. The shape — put down, leave alone, take up — is recognisably the same shape as Avahan and Visarjan, kept on the tithi clock.

And in Bengal, Bihar, Odisha and Assam, the great Saraswati Puja of the year is not in Navratri at all. It falls on Vasant Panchami, in the month of Magha, in the spring — a full festival with its own images and immersion. Saraswati is present during Durga Puja in the autumn, but as one of the deities who accompany Durga in the pandal rather than as the occasion.

None of these cancels another. They are regional answers to the same question — when do we hand the instruments of learning back — and a family that inherited one of them is not observing a corrupted version of a different one.

Keeping the sequence abroad

Away from India the sequence behaves differently from most festival dates, and in a way that is easier rather than harder.

Because the rites are keyed to the nakshatra, and the nakshatra is a position of the Moon rather than a local phenomenon, its boundaries are a single moment worldwide — 9:47 am IST on Saturday is 4:17 am in London and 11:17 pm on Friday in New York, but it is the same instant everywhere. What differs from place to place is only which of those boundaries your own sunrise falls between.

The practical consequence: compute your local sunrise, and check which nakshatra is running at that moment. For most of Europe, the Gulf and the Americas the four days will map onto the same four calendar dates as in India, because the nakshatras in 2026 are long enough to absorb the offset. Time zones far enough east — Australia, New Zealand, East Asia — should check the first day in particular, since Mula ends at 9:47 am IST and their sunrise sits well after that in Indian terms.

Our calendar tracks the festival days as they approach for your own location, and the live panchang will give you the prevailing tithi and nakshatra at your sunrise on any of these four days. That is the check worth doing once, rather than trusting a listing computed for a city you do not live in.
