What is a kundli in astrology?

A kundli is a Vedic birth chart: a diagram of where the Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, Rahu and Ketu stood in the zodiac at your exact time and place of birth, arranged into twelve houses from the rising sign. Every reading in Vedic astrology, from Dasha timing to matchmaking, is built on it.

What information do I need to generate an accurate kundli?

Your full birth date, the exact time of birth (to the minute if you have it), and your birth city. The ascendant shifts roughly every two hours, so an inaccurate birth time can move the whole house framework and change which planet is read as ruling which area of life.

Is a kundli the same thing as a horoscope?

"Horoscope" often means a generic sun-sign forecast shared by everyone born in the same month. A kundli is the full individual birth chart — the actual diagram of planetary positions at your birth — and is what a Vedic astrologer or app builds before writing any personalised reading.

Can two people born on the same day have the same kundli?

Only if born at essentially the same time and place. The Lagna changes roughly every two hours and house cusps shift continuously, so two births hours apart in the same city, or at the same clock time in different cities, usually produce meaningfully different charts.

What is the difference between a kundli and a Navamsa chart?

The kundli (Rashi chart) is the primary birth chart, built directly from the planets' zodiac positions at birth. The Navamsa (D9) is a second chart built by dividing each sign into nine parts, used to refine and cross-check the main kundli, particularly for marriage and overall chart strength, rather than replace it.

Core concept

Kundli

Kundli is the Vedic birth chart: a diagram showing the sign, house and degree of each of the nine grahas at the exact date, time and place of a person's birth. It is the starting point for every other reading in Vedic astrology, from Dasha timing to marriage matching, and it is built on the sidereal zodiac rather than the tropical zodiac used in Western charts.

Kundli is also spelled Kundali, and is called Janam Kundali, Janma Patrika or Jataka in different regions; in Devanagari it is कुंडली. It is not a sun-sign horoscope: a daily horoscope is a general Moon-sign forecast, while a kundli is the individual chart.

A glossary defines the term for everyone. Your chart shows whether it applies to you, and how strongly — in your Nakshatra, your Lagna and the Dasha running right now.

ExampleWhat a personal daily reading looks like

Written against

Your Moon sign
Your Nakshatra
Your current Dasha

Today the transiting Moon crosses your natal Moon — the one day this month your own Nakshatra is lit up directly.

Your current Mahadasha lord sits in the house this transit touches, which is why small decisions today carry further than usual.

A generic rashi horoscope cannot see any of this: it only knows the sign, not the degree, the Pada, or the period you are running.

What is a kundli?

A kundli is a diagram, not a prediction. It plots where the nine grahas (Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, and the lunar nodes Rahu and Ketu) sat in the sky at the exact date, time, and place of a birth, then arranges that snapshot into twelve houses radiating from the rising sign, the Lagna. Every later reading — a Mahadasha timeline, a Navamsa cross-check, a compatibility score — starts from this one diagram, which is why Vedic astrologers treat getting it right as the first step, ahead of any interpretation. You can see the most important pieces of yours in seconds with the free Lagna calculator.

How is a kundli calculated?

Three inputs build a kundli: birth date, birth time (ideally to the minute), and birth place, which fixes latitude, longitude, and time zone. Vedic astrology uses the sidereal zodiac, which tracks the fixed stars rather than the seasons, so every planet's longitude is shifted from its tropical value by the ayanamsa, about 24° today. Kundli Saathi applies the commonly used Lahiri ayanamsa and Swiss Ephemeris planetary data to place each graha in its sign, house, and degree.

What can a kundli tell you, and what can it not?

The raw chart shows placements and the planetary combinations (yogas) they form, but a placement alone rarely tells the whole story — the same graha in the same house reads differently depending on which sign it rules, what aspects it receives, and which timing period (Dasha) is active. That is why Vedic astrology avoids treating a chart as a fixed script: it describes tendencies and timing windows, and classical texts pair planetary reading with the reader's own effort and circumstances rather than presenting either alone as sufficient.

Kundli vs Western birth chart vs Rashi

A Western chart and a kundli can look structurally similar — twelve houses, planets, aspects — but they diverge in the zodiac they use (tropical vs. sidereal) and in which reference points get top billing. Western astrology leans on the Sun sign; Vedic astrology leans on the Moon's Rashi and Nakshatra, because those anchor the Vimshottari Dasha timing system. A kundli is also not the same as a Rashi: the kundli is the whole chart, while a Rashi is one of the twelve signs inside it, and "your Rashi" means only the sign the Moon occupied at birth.

Kundli at a glance

A kundli needs three inputs: the date, the exact time and the place of birth, and the place supplies latitude, longitude and time zone.
A kundli uses the sidereal zodiac, which is offset from the tropical zodiac by the ayanamsa, about 24° today; Kundli Saathi applies the Lahiri ayanamsa.
A kundli maps nine grahas — Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, Rahu and Ketu — across twelve houses counted from the Lagna.
The Lagna sets the house framework, while the Moon's Rashi and Nakshatra set the Vimshottari Dasha timeline.
The Lagna changes sign about every two hours, so a birth-time error of an hour or two can change the whole house layout.

Lagna
Lagna is the ascendant in Vedic astrology — the zodiac sign rising on the eastern horizon at the exact time and place of birth. It becomes the 1st house of the chart and sets the order of all twelve houses.
Nakshatra
Nakshatra is one of the 27 lunar mansions of Vedic astrology, each spanning 13°20′ of the zodiac — a finer division than the twelve Rashis. The Moon's Nakshatra at birth sets the starting point of the Vimshottari Dasha and is read as a strong indicator of disposition.
Rashi
Rashi is a zodiac sign in Vedic astrology — one of the twelve 30° divisions of the sidereal zodiac. "Your Rashi" usually means the sign the Moon occupied at birth, the sign a Vedic astrologer asks for first; the Sun's Rashi is closer to the Western sun sign.
Ayanamsa
Ayanamsa is the angular offset — about 24° today — between the tropical zodiac of Western astrology and the sidereal zodiac of Vedic astrology. Kundli Saathi applies the Lahiri ayanamsa, the most widely used in India, to place every planet in its Vedic sign.
