KP, Krishnamurti Paddhati, is the stellar system of Vedic astrology developed by K.S. Krishnamurti (1908-1972). It cuts each of the 27 nakshatras into nine unequal subs in the proportions of the Vimshottari dasha, so every degree of the zodiac has a sign lord, a star lord and a sub lord, and it reads the houses through their Placidus cusps. Where a kundli asks which sign a house is in, KP asks which planet rules the sub its cusp falls in, and which planets signify that house.
That makes KP very sensitive to the birth time: a cusp crosses a sub boundary every few minutes. This page shows the time each cusp's sub lord holds, computed from the cusp's own motion, so you can see how much your birth time can be off before a table changes.
This page computes the tables and explains how practitioners read them. It gives no verdicts, predictions or remedies.
We checked it the strict way. The requirements were written first; then a set of 54 test charts was drawn and committed before any comparison, and it was never used to tune anything. It spans births from 1921 to 2031, from the equator to 66.45 degrees north and south, with clock changes, negative UTC offsets and 27 edge cases built where tables break: cusps and planets within seconds of arc of a sign, star, pada, sub or sub-sub boundary, planets on a house cusp, planets at or near their stations, and a cusp where its geometry is most sensitive. Each was graded against Swiss Ephemeris 2.10.03, run outside this site. All 93,008 checks passed.

We also checked 6 of the charts by hand in Jagannatha Hora 8.0, set to the same KP settings. It identified the same KP ayanamsa on all 6, its planets agreed on all 6 and its mean node on 5, and all 156 star, sub and sub-sub lords of the nine bodies matched ours and Swiss Ephemeris's. Its house cusps sit a near-constant offset from Swiss Ephemeris's, close to the nutation in longitude, a few arcseconds, so near a sub boundary its cusp lords can differ from ours.
Each rule is labelled: direct where the research found it stated by Krishnamurti, derived where it follows by arithmetic or analogy, ours where it is a choice the sources do not make, and omitted where we know of a rule and do not apply it.
| Rule | What this page does | Source |
|---|---|---|
| Ayanamsa | Krishnamurti's, as Swiss Ephemeris defines it (No. 5), carried by precession; the mean value shown, the value with nutation subtracted from apparent positions | Derived: reproduces Krishnamurti's own table within his rounding |
| Houses | Placidus, solved from its definition: cusp 1 the Ascendant, cusp 10 the Midheaven, cusps 11, 12, 2 and 3 trisecting the semi-arcs | Direct by prescription: Krishnamurti prescribed Raphael's Placidian tables |
| House rule | A cusp is the start of its house; a planet is in house n from cusp n to cusp n+1; a house's owner is the lord of its cusp's sign | Direct |
| Stars and subs | 27 stars of 13 degrees 20 minutes, each cut into nine subs in Vimshottari proportions from the star's own lord: 243 continuous subs, 249 rows where six subs cross a sign | Direct (the nine-way split) |
| Sub-subs | Each sub cut into nine the same way; a sign boundary inside a sub does not restart them | Derived: Krishnamurti's dasa-bhukti analogy |
| Significators | Four levels, strongest first: A in the stars of the occupants, B occupants, C in the star of the owner, D owner | Direct (Readers 4 and 6) |
| Rahu and Ketu as agents | Planets conjoined with the node (the same sign) first, then its sign lord, then its star lord, one step only | Each agency, and conjoined planets first, direct; sign lord before star lord, and the same-sign conjunction, ours |
| Ruling planets | Krishnamurti's five at the moment and place of judgment, the day from sunrise to sunrise; the birth-moment list a labelled comparison | Direct (Reader 6); the birth list ours |
| A ruling planet in a retrograde planet's star | Flagged, with Krishnamurti's rejection rule explained, not applied | Omitted as a filter |
| Fifth significator level; agency through aspects and through the node's sub lord | Not shown | Omitted |
| Node | The mean node | Ours: no statement of mean or true was found |
| Beyond 66.5 degrees of latitude | Refused with a plain message: Placidus cannot be computed reliably there | Ours |
| Uncertainty | A value within our numerical uncertainty of a boundary shows every candidate, and everything derived from it carries the mark | Ours |
Three settings differ. KP uses Krishnamurti's ayanamsa, about 6 arcminutes smaller than the Lahiri ayanamsa most kundli calculators use, so every KP longitude is a few arcminutes larger. KP uses Placidus houses, which are unequal and start at their cusps, where a kundli usually uses whole-sign houses, so a planet can sit in a different house. And KP reads each cusp's star, sub and sub-sub lords, which a kundli does not show at all. The settings check on this page lists which lords of your chart change on Lahiri.
Each nakshatra of 13 degrees 20 minutes is cut into nine subs in the proportions of the Vimshottari dasha, a lord's years out of 120, starting from the star's own lord: Ketu's sub is 7/120 of the star (46 minutes 40 seconds) and Venus's 20/120 (2 degrees 13 minutes 20 seconds). The planet that rules the sub a point falls in is its sub lord. KP practitioners read a house mainly through the sub lord of its cusp, which is why this page shows every cusp's sub lord and how long it holds.
The same way, one level down: each sub is cut into nine parts in the Vimshottari proportions, starting from the sub's own lord, and the lord of the part a point falls in is its sub-sub lord. Where a sign boundary falls inside a sub, the parts run on across it rather than starting again. The worked lookup under your chart shows every step for your Ascendant.
Krishnamurti's ayanamsa as Swiss Ephemeris defines it (its No. 5), about 22 degrees 22 minutes in 1900 and carried forward by precession. It reproduces the table Krishnamurti printed within his arcminute rounding. Its value for your birth date is shown with your chart, as a mean value, with the value including nutation beside it. Other KP variants are not offered.
As exact as you have it. A sub spans from 40 arcminutes (the Sun's sub) to 2 degrees 13 minutes 20 seconds (Venus's), and the Ascendant moves about a degree every four minutes on average, so the Ascendant's sub lord can change within a few minutes and a sub-sub lord within seconds. This calculator takes seconds, and for every cusp it shows how much earlier or later the birth time would have to be for the sub lord to change, found from the actual motion of that cusp rather than an average.
Not for the cusps. A cusp moves about a degree every four minutes, so without a birth time its sign, star and sub lords, and every house built on them, are unknown. The planets' star and sub lords change much more slowly, except the Moon's, but this page computes a full KP chart and needs the time.
The planets that signify a house, at four levels, strongest first: (A) the planets in the stars of the house's occupants, (B) its occupants, (C) the planets in the star of its owner, and (D) its owner, the lord of its cusp's sign. This page lists them by house and by planet. Rahu and Ketu also act as agents: a node takes on the houses of the planets conjoined with it, then of its sign lord, then of its star lord.
The planets ruling the moment a question is judged: the day lord (the weekday runs from sunrise to sunrise), the lords of the Lagna's sign and star, and the lords of the Moon's sign and star, at the moment and place of judgment, with Rahu or Ketu counted when it sits in a sign one of them owns. This page computes them for this moment at a place you pick, and for the birth moment as a comparison.
Usually a setting, not an error. The ayanamsa: programs offer different KP variants, and Lahiri sits minutes of arc away. The node: this page uses the mean node; a true-node setting can differ from it by up to about 1.9 degrees. The houses: a cusp at the start of its house, as here, or in its middle. The day lord: a day from sunrise to sunrise, as here, or from midnight. The dasha: 365.25-day years here, with dates on the birthplace's calendar. Near a boundary, a few arcseconds of difference in any input can change a sub or sub-sub lord, which is why this page marks every value within its numerical uncertainty of a boundary with every candidate.
The time change to the nearest sub-lord boundary, holding the place and settings fixed: how many minutes earlier or later the birth would have to be for that cusp's sub lord to change, found by solving for the moment the cusp reaches the boundary within two hours either way. It is an estimate under these settings, rounded toward zero. It is not a confidence interval and not birth-time rectification, and it does not show that the rest of the chart stays the same.
No. It computes the tables KP practitioners read, and explains how they read them, without verdicts, predictions or remedies. Its accuracy against Swiss Ephemeris shows that the calculation is right; it is not evidence that KP's predictions work.
