What Is a Kundli? A Complete Guide
Understanding your Vedic birth chart and how to read it.
A Kundli, also called a Janam Kundli or Janam Kundali, is a map of the sky drawn for the exact moment and place of your birth. It records which sign was rising in the east, where each of the nine grahas stood, which of the 27 nakshatras the Moon occupied, and which planetary period you were born into. Vedic astrology (Jyotish) reads that map through the sidereal zodiac and the dasha timing system. This guide walks through how a Kundli is built and how each layer is traditionally read.
How Is a Kundli Calculated?
Building a Kundli starts with three inputs: your date of birth, your time of birth and your place of birth. Time and place fix the coordinates and the timezone, and from those come the sidereal longitude of the nine grahas, the rising sign (Lagna) on the eastern horizon, the twelve house cusps, your birth nakshatra and the divisional charts. Vedic calculation also applies an ayanamsa, a correction for the slow drift between the sidereal and tropical zodiacs; this tool uses the Lahiri (Chitrapaksha) ayanamsa, the standard adopted in most Indian almanacs. The Lagna moves quickly, so even a small change in birth time can shift your house placements. That is why an accurate birth time matters most for the house-level and dasha layers of the chart, and why a chart built on a noon default is honest about which of its layers are approximate.
The 12 Houses (Bhavas)
The twelve houses, or bhavas, divide the chart into areas of life, counted from your rising sign. Each carries its own traditional themes: the first the self, the seventh partnership, the tenth career and public standing. In Vedic tradition a house is never judged in isolation. It is read together with the sign on it, the placement and dignity of its ruling lord, the planets sitting inside it, and the dashas currently running.
| House | Traditionally signifies |
|---|---|
| 1st (Lagna) | Self, personality, appearance |
| 2nd | Wealth, speech, family |
| 3rd | Siblings, courage, effort |
| 4th | Home, mother, comfort |
| 5th | Children, creativity, intelligence |
| 6th | Enemies, health, service |
| 7th | Marriage, partnerships |
| 8th | Longevity, transformation |
| 9th | Fortune, father, dharma |
| 10th | Career, status, karma |
| 11th | Gains, income, wishes |
| 12th | Losses, liberation, foreign lands |
The 9 Planets (Navagraha)
Vedic astrology works with nine grahas, together called the Navagraha. Seven are visible bodies: the Sun, Moon, Mars, Mercury, Jupiter, Venus and Saturn. The other two are the lunar nodes, Rahu and Ketu, the points where the Moon's path crosses the ecliptic. Each graha is traditionally said to govern particular themes, and its influence is read through the sign it occupies, the house it sits in, its dignity and the dasha it rules. That is why the same planet reads differently from one chart to the next: Saturn in the 10th is not the same Saturn as Saturn in the 12th.
| Graha (Planet) | Traditionally governs |
|---|---|
| ☉︎Sun (Surya) | Soul, vitality, father, authority |
| ☽︎Moon (Chandra) | Mind, emotion, mother, comfort |
| ♂︎Mars (Mangal) | Energy, courage, drive, siblings |
| ☿︎Mercury (Budha) | Intellect, speech, commerce |
| ♃︎Jupiter (Guru) | Wisdom, growth, fortune, teachers |
| ♀︎Venus (Shukra) | Love, relationships, art, comfort |
| ♄︎Saturn (Shani) | Discipline, patience, karma, longevity |
| ☊︎Rahu | Ambition, worldly desire, the unconventional |
| ☋︎Ketu | Detachment, spirituality, past karma |
The Dasha System
The Vimshottari dasha is the timing framework at the heart of Jyotish. It splits a notional 120-year span into planetary periods called mahadashas, each ruled by one graha and running for a fixed number of years, with nested sub-periods inside them: the antardasha, and inside that the pratyantardasha. The order and length of your dashas are set by the Moon's position within its nakshatra at birth, which is why two people born on the same date a few hours apart can open their lives in different periods. In Vedic tradition the ruling planet of the active period is read as the dominant theme of that phase, tending to bring forward the houses that planet rules and occupies, while the sub-periods are read as the shorter shifts of mood and circumstance inside it. Your kundli lays out all three levels with their dates, mahadasha, antardasha and pratyantardasha, and marks the one you are running today: a timing map to work with, not a prediction of specific events.

Yogas are specific planetary combinations that, in Vedic tradition, are linked to particular life themes. The best known are the Raja Yogas, formed when the lord of an angular house and the lord of a trine come together, read as marks of authority and achievement. Vipareeta Raja Yoga is the odd cousin of that family, formed from the lords of the difficult houses, and tradition reads it as advantage arriving through obstacles. Dharma-Karmadhipati Yoga joins the 9th and 10th lords, the houses of fortune and of work. The Dhana Yogas are the wealth-building combinations, involving the lords of the 2nd and 11th. Classical texts describe many more. A yoga on paper is not the whole story either: its strength depends on house placement, planetary dignity and dasha timing, and it can stay dormant until its ruling period arrives. Your kundli surfaces the classical yogas that actually form in your own chart, whichever families they belong to, and gives each one a strength percentage plus the planets and houses that build it, so a yoga formed by two weak planets in a hard house does not read the same as one formed by two strong ones.
Planetary Strength: Ashtakavarga and Shadbala
Knowing where a planet sits is only half the reading. The other half is whether it is strong enough to act on that placement, and Jyotish has two classical systems for measuring it. Ashtakavarga gives each sign a tally of benefic points called bindus, contributed by the seven planets one at a time; each planet's own chart is scored from eight reference points, the other planets and the Lagna, which is where the "ashta" in the name comes from. Add those seven charts together and you get the Sarvashtakavarga, a number for every sign in your chart. A house carrying 30 bindus and a house carrying 22 are read very differently even with the same planet in them. Shadbala takes the other route and scores each graha directly across six sources of strength: position in the zodiac, direction in the chart, time of birth, motion, natural strength and aspect. Your kundli gives you both, the bindu tables per sign, and the Shadbala figures for the seven grahas from the Sun to Saturn, which are the seven the system is defined for. Most free kundli generators stop before this layer; it is the part of the paid 50-page reports that actually changes how a chart reads.
Remedies: Gemstones and Rudraksha
Vedic tradition prescribes remedies (upayas) for planets it reads as weak or afflicted, and the two most commonly asked about are gemstones and rudraksha beads. A gemstone is chosen for a specific planet in your chart rather than for your sun sign, which is why the ruby, pearl, coral, emerald, yellow sapphire, diamond and blue sapphire of the classical set are not interchangeable. Your kundli names the stone tradition ties to your chart along with the details practitioners ask about: which finger, which metal, the weight, the day to begin, the acceptable substitutes if the primary stone is out of reach, and the flaws that traditional texts say make a stone unsuitable. Rudraksha beads are classified by mukhi, the number of natural faces on the seed, and a mukhi is suggested the same way. These are traditional practices offered for your own consideration, not medical, financial or marital advice, and nothing in your chart obliges you to buy anything.
The KP System (Krishnamurti Paddhati)
Krishnamurti Paddhati is a twentieth-century Indian refinement of Vedic astrology, and it is the method a large share of practising Indian astrologers now use for timing questions. Its central idea is subdivision: KP splits each nakshatra into unequal parts governed by sub-lords, so instead of asking only which sign and nakshatra a planet occupies, it asks which sub-lord governs that exact degree. KP also uses cusps rather than whole signs for house boundaries, which makes the house a planet falls in depend more finely on your birth time. Your kundli includes a KP layer alongside the traditional one: the star lord and sub-lord for each of the nine planets and for each of the twelve cusps. If your family astrologer works in KP, this is the table they will ask for.
Varshaphal: Your Annual Kundli
The birth chart is fixed for life, but Indian tradition also reads a fresh chart each year, called the Varshaphal or annual kundli. It is cast for the moment the Sun returns to the exact position it held at your birth, which falls near your birthday but rarely on it, and it is read by the Tajika method rather than by the birth-chart rules. Its distinctive marker is the Muntha, a point that advances one house every year and is read as the area of life in focus for that cycle, alongside the Tajika lords given charge of the twelve months. Your kundli includes the annual chart for the current solar-return year, with the Muntha and those lords named. Tradition treats it as a lens on the year's themes, read against your running dasha rather than in place of it.
Why Birth Time Matters (and What Happens If You Don't Have One)
Birth time is the most sensitive input in a Vedic chart. The Lagna, or rising sign, changes roughly every two hours, and every house placement is measured from it, so a shift in birth time moves the whole house framework. Ten or fifteen minutes can be enough to push a planet from one house into the next, alter the balance of the active dasha and change which yogas form. So if you have the time on your birth certificate or hospital records, use it rather than an estimate.
If you don't have it, you can still generate your kundli. Tick the "I don't know my birth time" box and we calculate for 12:00 noon on your birth date, the same convention Indian astrologers use when a time is genuinely lost. What survives that: the sign each planet occupies (the Moon is the only one that can shift, and only if you were born within about a day of it changing sign), your rashi, your nakshatra in most cases, the doshas that depend on planetary signs, and much of the yoga picture. What gets marked approximate on your result: your Lagna and therefore every house placement, the house-based dosha readings, and the exact dates in your dasha timeline, since those are set by the Moon's precise position. A noon chart is a real chart with a stated margin, not a guess dressed up as certainty. If the time later turns up, run it again and compare.
Kundli vs Western Chart
A Kundli and a Western natal chart are drawn from the same sky and read by different conventions. Vedic astrology uses the sidereal zodiac, fixed to the constellations, and leans on the nakshatras and the dasha system for timing. Western astrology uses the tropical zodiac, anchored to the seasons, and puts its weight on planetary aspects and transits. Because of the ayanamsa gap, a planet can land in one sign in your Kundli and in the next sign along in a Western chart, so a Western Aquarius Sun is often a Vedic Capricorn Sun. Neither framework is more "correct"; they ask different questions and answer them in their own language. This tool works entirely in the Vedic (sidereal) system with the Lahiri ayanamsa.
See the Birth Chart tool →What a Kundli Is Traditionally Read For
Beyond its mechanics, a Kundli is consulted for the everyday questions people bring to it, and Vedic tradition reads each through particular houses and their lords, always alongside dignity and the running dasha rather than any single placement. Career is read mainly from the 10th house (karma and public standing) and its lord, with Saturn and the Sun weighed in. Marriage and partnership are read from the 7th house and Venus, cross-checked in the Navamsa (D9). Wealth is read from the 2nd house (accumulation) and the 11th (gains and income). Health and vitality are approached through the 6th and 8th houses. Education and children are read from the 5th house and Jupiter. Your kundli sets out the houses, their lords and the placements these readings draw on, the planetary positions and the dasha timeline, but a traditional reading weighs them together, which is where a qualified astrologer adds what a generated chart cannot. None of this is a fixed prediction; it is the framework tradition uses to ask the question.
