Ghatak Chakra — the Harmful Elements

The Ghatak (Ghat) Chakra explained: one lunar month, tithi group, weekday, nakshatra, yoga, karana, prahar, Moon rashi and lagna held harmful for each janma rashi — what it is, what it is not, and where the published tables disagree.

What the Ghatak Chakra is

Ghata (घात) means to strike, to injure. The Ghatak Chakra — also written Ghat Chakra or Ghataka Chakra — is a small classical table that names, for each janma rashi (the sign your Moon occupies at birth), the time-elements held to be injurious for you:

Element What it is
Ghat masa One lunar month of the year
Ghat tithi One tithi group — Nanda, Bhadra, Jaya, Rikta or Purna
Ghat vara One weekday
Ghat nakshatra One of the 27 nakshatras
Ghat yoga One of the 27 yogas
Ghat karana One of the 11 karanas
Ghat prahar One eighth of the day-and-night
Ghat chandra rashi One sign for the transiting Moon
Ghat lagna One rising sign — printed as a male/female pair

It is used mostly in muhurta: when a date is being chosen for something that matters, the native’s ghat elements are the ones you avoid if avoiding them is cheap. It is a screening table, not a prediction.

And what it is not

Three things it is worth being clear about, because the chakra is often presented as more than it is.

It is not a calculation. Nothing about your birth time enters except your Moon’s sign. Two people born in the same fortnight, in different countries, decades apart, share a ghatak row if their Moons shared a sign. The astronomy happens in the panchang the row is checked against, never in the row itself.

It is not a verdict on a day. A day matching one element out of seven is ordinary; the tradition’s caution scales with how much of the row a day hits. AstroShruti therefore always shows the count and the names of the elements a day matched, never a bare red mark.

It is not one settled table. Published ghatak tables genuinely disagree with each other. That is important enough to have its own section below.

The table

Janma rashi is your Moon’s sign, not your ascendant and not your Sun sign.

Janma rashi Masa Tithi Vara Nakshatra Yoga Karana Prahar Chandra Lagna (M/F)
Mesha Kartik Nanda Sunday Magha Vishkambha Bava 1 Mesha Mesha / Tula
Vrishabha Margashirsha Purna Saturday Hasta Sukarma Shakuni 4 Kanya Vrishabha / Vrishchika

Kumbha Chaitra Jaya Thursday Ardra Ganda Vanija 3 Dhanu Mithuna / Dhanu

The tithi column names a group, not a tithi

This trips people up. The five tithi groups each contain one tithi from every fifth of the paksha:

Group Tithis (of each paksha)
Nanda 1, 6, 11
Bhadra 2, 7, 12
Jaya 3, 8, 13
Rikta 4, 9, 14
Purna 5, 10, 15

So a Purna native does not have one unsafe tithi a fortnight — they have three, in each paksha, i.e. six a month.

Why one hit lasts a month and another lasts a day

The nine elements run on completely different clocks, and this is the single most useful thing to understand about a personal ghatak calendar:

Element How often it comes round
Ghat prahar Every day, for about three hours
Ghat tithi Three days per paksha, six per month
Ghat vara Once a week
Ghat chandra rashi About 2¼ days a month
Ghat nakshatra About one day a month
Ghat yoga About one day a month
Ghat karana Several days a month
Ghat masa A whole lunar month, once a year

That last row is why a ghatak calendar looks lopsided. In your ghat month, every single day carries at least one hit — not because that month is uniquely dangerous, but because a month-long element is being reported day by day. Read the number of hits, not the presence of one.

The male and female lagna

The lagna column is printed as a pair in the sources that carry it, and the ones that name the columns call them male and female. The two are always exactly seven signs apart — a structural regularity that holds in all twelve rows, so a transcription error in one column is caught by the other.

AstroShruti shows both and marks which one applies to the native.

How well attested is this table?

Honestly: unevenly, and it would be misleading to print it as though every cell were equally solid. Here is what stands behind it.

The table was audited against eight independent published sources before it shipped — two full twelve-row tables, and six single-row confirmations from a printed janma-patri, two commercial astrology APIs, two prose worked examples and one vendor app. What that bought, column by column:

  • Tithi group and vara — the two full tables agree on all twelve rows. Settled outright.
  • Nakshatra — they agree on eleven of twelve. The twelfth reads “Dveja” in one, which is not a nakshatra at all; two other sources give Bharani there, so Bharani wins 3–1.
  • Ghat chandra rashi — confirmed on four different rows by four different publishers, including a printed patri that gives it as an ordinal (“Moon: Second”) rather than a sign name.
  • Masa, yoga, karana and prahar — only one of the two full tables carries these columns. Four other publishers each reproduce it exactly on a different row, which is good evidence that the transcription is faithful and no evidence at all about the eight rows nobody sampled. AstroShruti marks those eight rows as resting on a single transcription, in the app, in words.

Two divergences are worth knowing because you may well meet them elsewhere:

  • A widely reproduced Hindi list gives an entirely different ghat nakshatra series. It repeats three nakshatras, and agrees with neither full table. It is real and published; it is not what we use.
  • One Hindi source gives Vrishabha’s ghat yoga as Shula where two others say Sukarma. We follow the majority.

And one thing is deliberately absent: a ghat graha column. One vendor app prints one. No published ghatak table has that column at all, so there is nothing to check it against — and one screenshot is not a source. The same standard keeps paya out of the Avakahada card until a second reference chart settles it.

The unsettled month: amanta or purnimanta?

This is the one genuinely open question in the chakra, and it changes the answer on roughly half of every month.

Lunar months come in two conventions. Amanta months end at the new moon; purnimanta months end at the full moon. Through every Krishna paksha the same day therefore carries two different month names — and the ghat masa flag fires on two different halves of the year depending on which one you mean.

Six publications that carry or sell the ghat masa column were checked. Not one states the convention. Not the Hindi table the column comes from, not the Poddar/Rath lineage, not either prose worked example, not a panchang publisher’s own ghat-chakra page, not a commercial ghat-chakra report product. Silence in all six.

Where the sources are silent, the honest move is not a coin flip and not a silent pick. AstroShruti:

  1. Reads the column as purnimanta, on provenance. The masa column exists only in the North-Indian printed-patri and Hindi-panchang tradition, and that tradition reckons lunar months purnimanta. The sources that are not from it carry no masa column at all — which is itself the evidence about where the column came from.
  2. Puts both readings on every day, so the reading we did not act on is never hidden from you.
  3. Says which one it used, in the app.

One dated worked example in a Krishna paksha would settle this. If you have one, we would like to see it.

For the two conventions themselves, see Amanta vs Purnimanta.

Where you will find it in AstroShruti

  • Birth Details carries your ghatak row in full, with the attestation note and both lagna columns.
  • The Hindu Calendar badges the days of a month that hit your row, and says which elements they hit.
  • Muhurat warns when the day you are looking at is one of them.
  • Agastya, the AI astrologer, checks a date against your row when you ask whether a day suits you — and will tell you when a column rests on a single published transcription.

Notes on this chakra

  • Keyed on the Moon’s sign, never the ascendant or the Sun sign.
  • A fixed table, not a computation — the panchang it is checked against is what is computed.
  • Each day is scored at sunrise, the almanac convention the month grid uses.
  • The count of matched elements matters more than the fact of a match.
  • The masa convention is defaulted, not settled; both readings always ship.
  • No ghat graha column, on purpose.

Frequently asked questions

What is the Ghatak Chakra?

*Ghata* means to strike or injure. The Ghatak Chakra is a fixed classical table that names, for every janma (Moon) rashi, one lunar month, one tithi group, one weekday, one nakshatra, one yoga, one karana, one prahar, one Moon rashi and one lagna held to be injurious for natives of that rashi. It is a lookup, not a computation — nothing is calculated from your birth time except which row you are on.

Is a ghatak day a bad day?

It is a caution the tradition raises, not a verdict. The chakra is a screening table used mostly in muhurta — when choosing a date for something important, one avoids the native's ghat elements where it is cheap to do so. A day that hits one element out of seven is a very different thing from a day that hits four, which is why AstroShruti counts the hits and shows you which ones they were.

Why does my ghat month last a whole month while my ghat weekday is one day?

Because the elements have wildly different durations, and the chakra names one of each. Your ghat vara comes round once a week; your ghat tithi group is three tithis in every paksha; your ghat nakshatra is roughly one day a month; but your ghat masa is a whole lunar month, once a year. That is why a personal ghatak calendar shows long flagged stretches rather than scattered days — the masa hit is a month, by construction.

Why are there two ghat lagnas?

The classical table prints a pair, and the sources that name them call one the male column and the other the female. They are always exactly seven signs apart. AstroShruti shows both and marks which one applies, rather than silently picking one — the pair is what the tradition printed.

Other sites show a ghat graha. Why doesn't AstroShruti?

Because no published ghatak table we could find has a graha column at all. One vendor's app prints one; that is a screenshot, not a source, and there is nothing to audit it against. The house rule here is that a classical table needs at least two independent published sources before it ships, so the column is left out rather than guessed at.

Is the ghat month amanta or purnimanta?

Nobody says — and it matters, because the two conventions disagree through every Krishna paksha. Six publications that carry or sell the ghat masa column were checked and not one states the convention. AstroShruti reads it as **purnimanta** on the strength of where the column comes from, and puts **both** readings on every day it shows, so the other one is never hidden from you.
