Panchak
Panchak is the five-day stretch when the Moon transits Dhanishta to Revati. The five prohibited acts, the weekday-named types, and why it is not Panchaka Rahita.
What is Panchak?
Panchak — panchaka, “the set of five” — is the roughly five-day stretch in every lunar month when the Moon transits the last five nakshatras:
- Dhanishta (its second half only)
- Shatabhisha
- Purva Bhadrapada
- Uttara Bhadrapada
- Revati
The Moon takes about a day per nakshatra, so the window runs a little under or over five days, and because the Moon returns to the same place every sidereal month, Panchak comes round about once a month — roughly every 27 days. It is not rare or ominous in its frequency; it is a regular feature of the calendar, occupying something like a sixth of every month.
The same window is often stated as the Moon in Kumbha or Meena — Aquarius or Pisces, sidereally. That is not a second rule. The last five nakshatras (from Dhanishta’s midpoint through Revati) tile exactly onto those two signs, so the two statements pick out the identical stretch. Almanacs use whichever form suits them.
The five prohibitions
This is the part worth getting right, because Panchak has drifted in popular usage into a general-purpose bad omen, and that is not what it is.
Panchak names five specific acts, and its scope is those acts:
| Act | The classical concern |
|---|---|
| Roofing or thatching a house | Laying a roof during Panchak invites its repetition — the work will have to be done again. |
| Travelling south | The south is Yama’s direction; the prohibition is on beginning a southward journey, not on travel generally. |
| Making a bed or cot | A bedstead built in Panchak is held to invite illness or worse for its occupant. |
| Gathering fuel wood | Collecting or stacking wood and grass; the concern is fire. |
| Cremation without the prescribed rite | A death during Panchak is held to portend five more in the family unless a specific expiatory rite is performed. |
Note the shape of that list. Four of the five are domestic and material — roof, bed, firewood, a journey. They are the concerns of a household, not of a horoscope. The fifth is the one that gives Panchak its dread, and it is the reason the word carries a weight the other four would never have earned.
Weddings are not on the list. Nor are business, purchases, signing, study, medical treatment, or northward travel. A great deal of everyday anxiety about Panchak is anxiety about things the rule never mentioned.
The cremation rite
Because it is the source of the fear, it is worth stating what tradition actually prescribes rather than leaving it implied. Where a death falls in Panchak, the remedy is not to delay the cremation — that is not permitted. The prescribed practice is to place five figures made of kusha grass or flour on the pyre alongside the body, with the appropriate mantras, so that the five deaths the window is said to demand are accounted for symbolically. The rite exists precisely so that the prohibition need not obstruct what cannot be postponed.
The five types, by weekday
Panchak takes its character from the weekday on which it begins, and this produces the five names — which are, confusingly, close to the five names used in the entirely separate Panchaka Rahita scheme.
| Begins on | Name | Character |
|---|---|---|
| Sunday | Roga Panchak | Illness; adverse for health |
| Monday | Raja Panchak | Royal — favourable; good for position, authority, property |
| Tuesday | Agni Panchak | Fire; adverse for anything involving flame, machinery, dispute |
| Friday | Chora Panchak | Theft; adverse for valuables, transactions, travel with goods |
| Saturday | Mrityu Panchak | Death; the grave one |
Wednesday and Thursday are absent from the list. A Panchak beginning on either is regarded as carrying no special character — an ordinary Panchak, with the five prohibitions and nothing added.
Raja Panchak is favourable. This is not a technicality. A Panchak that starts on a Monday is read by most sources as a good window for exactly the things authority touches — property, position, dealings with the state — and treating it as adverse because the word “Panchak” appears in its name is a straightforward error.
Not Panchaka Rahita
These two are different schemes that share the Sanskrit root pancha, and they are routinely conflated.
| Panchak | Panchaka Rahita | |
|---|---|---|
| What sets it | the Moon’s nakshatra | nakshatra + tithi + weekday + rising sign |
| Timescale | about five days, monthly | changes with each rising sign, all day |
| Verdict is about | five named household acts | five doshas scored per lagna period |
| Named types | by the starting weekday | by a remainder mod 9 |
The name overlap is nearly total — both produce a Mrityu, a Raja, an Agni, a Chora and a Roga — and it is coincidental in the sense that neither list is derived from the other. A day inside a Panchak can read Shubha all afternoon on the Panchaka Rahita table, and a day well outside one can read Mrityu Panchaka at noon. They are answering different questions.
If you came here looking for today’s rising-sign verdicts, that is Panchaka Rahita, and it is computed.
What we do not compute
Plainly, because this article should not imply otherwise:
AstroShruti does not compute Panchak. There is no Panchak window in the panchang, no Panchak flag on any date, and no Roga/Raja/Agni/Chora/Mrityu Panchak label anywhere in the app. This page is an explainer, not a companion to a feature.
What the app does give you is the input the rule runs on. The panchang reports the Moon’s nakshatra and its spans for any date and place — so if that nakshatra is Shatabhisha, Purva Bhadrapada, Uttara Bhadrapada or Revati, or the back half of Dhanishta, you are in Panchak, and the nakshatra’s start and end times bound it. Determining the weekday it began on, and hence which of the five types it is, is likewise something you can read off the panchang but which the app will not name for you.
The similarly named Panchaka Rahita muhurat table is computed, for any place and date. It is a different thing, and the section above explains how.
Frequently asked questions
How many days does Panchak last?
About five, which is where the name comes from — panchak means "the set of five". It is five nakshatras, not five calendar days, so the exact length follows the Moon's speed and is usually a little under or a little over five days rather than exactly five.
Is everything forbidden during Panchak?
No, and this is the most common misunderstanding. Panchak names five specific acts to avoid — roofing, southward travel, making a bed or cot, gathering fuel wood, and cremation without the prescribed rite. It is not a general prohibition. Weddings, business, travel other than southward, and everyday work are not in its scope, whatever popular usage suggests.
Is Panchak the same as Panchaka Rahita?
No. They share a root word and nothing else. Panchak is a five-day window set by the Moon's nakshatra. Panchaka Rahita is a moment-by-moment calculation scored per rising sign from four inputs, several times a day. A day inside Panchak can be entirely clean on the Panchaka Rahita table. See the Panchaka Rahita article for that scheme.
Why does the Moon in Kumbha and Meena define it?
The last five nakshatras — the second half of Dhanishta through Revati — correspond exactly to the sidereal signs Kumbha (Aquarius) and Meena (Pisces). So "Moon in the last five nakshatras" and "Moon in Kumbha or Meena" describe the same stretch. Some almanacs state it one way, some the other; they agree.
Which Panchak is the worst?
Mrityu Panchak, which begins on a Saturday. Roga and Chora Panchak are treated as adverse in their own domains. Raja Panchak, beginning on a Monday, is widely read as favourable rather than adverse — it is not a bad window at all in most tellings.
