A Kundli is the Vedic astrology map of the sky at the exact moment you were born, and this free tool builds your full Janam Kundli from your birth date, time, and place in a couple of seconds. You get the whole chart at once: the Lagna or ascendant, your Rashi or Moon sign, the positions of the nine grahas across the twelve signs and houses, your birth Nakshatra, your Vimshottari Dasha timeline, and your Mangal Dosha status. If you want to check compatibility, the same page runs Guna Milan matchmaking. Nothing is held back behind a payment, and nothing is sent off your device.
This page explains what a Kundli actually is, how it is put together, how to read each part of the result, and where the tradition comes from. It is written to be useful whether this is your first chart or your fiftieth. You will not be asked to sign up, hand over an email, or buy a report to see the parts that matter.
What Is a Kundli (Janam Kundli)?
The word Kundli refers to a birth chart in Vedic astrology, the system also known as Jyotish. Janam means birth, so a Janam Kundli is your birth chart specifically, cast for the instant you arrived. Astrologers in India have drawn these charts for centuries, and the same core method still sits behind every modern calculator, including this one.
A Kundli captures three layers of information laid over each other. The first layer is the twelve signs of the zodiac, from Mesha (Aries) through Meena (Pisces). The second is the twelve houses, called bhavas, which represent areas of life such as self, wealth, family, and career. The third is the set of planets, the grahas, dropped into those signs and houses based on where they truly were in the sky at your birth. Reading a Kundli means reading how those three layers line up.
Because the chart is anchored to a precise time and place, no two Kundlis born minutes apart at the same spot are identical in every detail, and the ascendant in particular can differ. That sensitivity is why the tool asks for your birth time as exactly as you can give it.
The Sidereal Zodiac and Why a Kundli Looks Different
Here is the single biggest thing that sets a Kundli apart from the Western horoscope in a magazine. Vedic astrology uses the sidereal zodiac, which is tied to the actual positions of the fixed stars. Western astrology uses the tropical zodiac, which is tied to the seasons and the spring equinox. Over many centuries these two frames have drifted apart because of a slow wobble in the Earth's axis called precession.
To bridge that gap, Vedic astrology applies a correction called the ayanamsa. The ayanamsa is the angular distance between the two zodiacs, and right now it sits at roughly twenty four degrees. The most widely used value in India is the Lahiri ayanamsa, also called Chitrapaksha, which is the standard adopted by the Indian government's calendar reform committee. To build a sidereal Kundli, you take the tropical position of each planet and subtract the ayanamsa.
The practical result is that your Vedic signs are often shifted one sign earlier than your Western ones. Someone who is a late Aries in a tropical chart may well be a Pisces Rashi in a Kundli. This is not a mistake in either system. They simply measure from different starting lines, and the ayanamsa is what translates between them.
The Lagna: Your Ascendant and the Twelve Houses
The Lagna, or ascendant, is the sign that was rising over the eastern horizon at the moment of your birth. It anchors the entire Kundli, because the Lagna becomes the first house, and every other house is counted from there. In most Vedic charts the whole first sign is treated as the first house, which keeps the layout clean and easy to read.
The Lagna matters so much because it moves fast. The rising sign changes roughly every two hours as the Earth turns, so two people born on the same day in the same city can have different ascendants if their birth times are far enough apart. This is exactly why an accurate birth time changes your Kundli more than almost any other input, and why the tool treats the minute of birth as important rather than optional.
The twelve houses each govern a slice of life. In brief, the first house is the self and body, the second is wealth and speech, the third is courage and siblings, the fourth is home and mother, the fifth is children and creativity, the sixth is health and rivals, the seventh is marriage and partnership, the eighth is transformation and longevity, the ninth is fortune and belief, the tenth is career and status, the eleventh is gains and networks, and the twelfth is loss, sleep, and release. A planet colors the house it lands in.
The Rashi: Your Moon Sign and Why It Leads
If a Western horoscope leads with your Sun sign, a Kundli leads with your Rashi, which is your Moon sign. In Vedic thought the Moon stands for the mind, the emotions, and the inner self, so where the Moon sat at birth is treated as a window into how you feel and react. When someone in India asks your sign, they usually mean your Rashi.
Your Rashi is simply the sign the Moon occupied at your birth, measured in the sidereal zodiac. Because the Moon moves quickly through the signs, spending only about two and a quarter days in each, the Rashi can change within a single day. The tool computes the Moon's exact sidereal longitude and reports the Rashi, along with a short note on what that placement traditionally signifies.
The Nine Grahas: Planets, Rahu, and Ketu
Vedic astrology works with nine grahas rather than the ten bodies of a modern Western chart. The seven visible ones are the Sun (Surya), the Moon (Chandra), Mars (Mangala), Mercury (Budha), Jupiter (Guru), Venus (Shukra), and Saturn (Shani). The last two are not physical planets at all. They are Rahu and Ketu, the north and south lunar nodes, the two points where the Moon's path crosses the Sun's path in the sky.
Rahu and Ketu always sit exactly opposite each other, and they carry heavy symbolic weight in a Kundli. Rahu is linked to worldly desire, ambition, and the unusual, while Ketu is linked to detachment, the past, and spiritual release. Traditional Vedic astrology does not use Uranus, Neptune, or Pluto, which is another way a Kundli differs from many Western charts. Your Kundli lists all nine grahas with their sign, their house, and their exact degree.
Nakshatras: The 27 Lunar Mansions
Layered on top of the twelve signs is a finer grid of twenty seven Nakshatras, or lunar mansions. Each Nakshatra spans thirteen degrees and twenty minutes of the zodiac, and together they wrap the full circle. They are counted from Ashwini at the start of sidereal Aries through Revati at the end of Pisces. Your birth Nakshatra is the one the Moon occupied when you were born, and it is often called your birth star.
Nakshatras add texture that the signs alone miss. Each one has a ruling planet, a symbol, a guiding deity, and a cluster of traits, and each is split into four quarters called padas that sharpen the reading further. Beyond personality, the Nakshatra of the Moon is the anchor for one of the most used tools in a Kundli, the Vimshottari Dasha, because the ruling planet of your birth Nakshatra decides which planetary period you were born into.
Vimshottari Dasha: The 120-Year Timeline
A Dasha is a planetary period, a stretch of time said to be governed by one graha. The most widely used Dasha system is the Vimshottari Dasha, which lays your life out as a repeating cycle of one hundred and twenty years divided among the nine grahas. Each planet rules a major period, called a Mahadasha, of a fixed length: Ketu seven years, Venus twenty, the Sun six, the Moon ten, Mars seven, Rahu eighteen, Jupiter sixteen, Saturn nineteen, and Mercury seventeen. Those add up to one hundred and twenty.
The clever part is where your timeline starts. The ruling planet of your birth Nakshatra sets the Mahadasha you were born under, and the exact position of the Moon inside that Nakshatra sets how much of that first period was already spent before birth. The tool measures the Moon's progress through its Nakshatra and computes the balance left, then rolls the full sequence forward from your birth date so you can see which period you are in now and what comes next.
Each Mahadasha is also split into nine sub periods, called Antardashas or Bhuktis, ruled by the planets in the same order and scaled to the length of the parent period. That nesting is what lets astrologers point to a specific window rather than a broad decade. Your Kundli shows the running Mahadasha and its sub periods along a clear timeline.
Doshas: Mangal Dosha and the Manglik Question
A dosha is a flaw or affliction in a Kundli, a placement that tradition treats as needing care. The most talked about is Mangal Dosha, also called Manglik or Kuja Dosha. It occurs when Mars sits in specific houses of the chart, most commonly the first, second, fourth, seventh, eighth, or twelfth, counted from the Lagna, and in some schools from the Moon or from Venus as well.
Mangal Dosha comes up mostly during marriage matching, where tradition holds that a Manglik and a non Manglik may face friction. It is worth keeping perspective here. The placement is common, many respected astrologers view it as easily balanced, and there are recognized remedies and cancellations within the tradition itself. The tool flags your Mangal Dosha status plainly, tells you which houses triggered it, and leaves the interpretation to you. Other doshas exist too, such as Kaal Sarp and Sade Sati, and the chart gives you the raw placements to explore them.
Kundli Matching: Guna Milan and the Ashtakoot System
For marriage, the classic use of a Kundli is matchmaking, known as Kundli Milan or Guna Milan. The dominant method is Ashtakoot Milan, which scores compatibility across eight factors, the eight kootas, for a maximum of thirty six points. Most of the scoring flows from each person's Nakshatra and Rashi rather than the whole chart, which is why matching can be done quickly.
The eight kootas and their maximum points are: Varna, worth one point, for temperament and ego; Vashya, worth two, for mutual influence; Tara, worth three, for health and destiny; Yoni, worth four, for physical and instinctive compatibility; Graha Maitri, worth five, for mental and intellectual bond; Gana, worth six, for nature and disposition; Bhakoot, worth seven, for emotional and financial harmony; and Nadi, worth eight, for health and progeny. Add them up and the ceiling is thirty six.
As a rough guide, eighteen out of thirty six is the traditional minimum for a match to be considered workable, scores from eighteen to twenty four are fair, twenty five to thirty two are good, and anything higher is excellent. A number alone is never the full story. Astrologers weigh doshas, the strength of the seventh house, and the two full charts together. Our matchmaking view gives you the total, the koota by koota breakdown, and the Manglik status for both people, so you can see where the points came from.
North Indian and South Indian Chart Styles
A Kundli can be drawn in more than one visual style, and the two most common are the North Indian and South Indian layouts. They hold identical information. Only the drawing differs, so pick the one you find easier to read.
The North Indian chart is a diamond inside a square. In this style the houses are fixed in place, with the first house always at the top center, and the sign numbers rotate to sit inside the houses. It is a house based layout, so your eye goes to a fixed position to find, say, the seventh house of partnership. The South Indian chart is a square grid of twelve boxes around an empty center. Here the signs are fixed, with Aries always in the same box, and the ascendant is marked so the houses count around from it. There is also an East Indian style used in parts of the country. The tool can present your Kundli in the North Indian and South Indian formats so it feels familiar no matter where you learned to read charts.
Divisional Charts and the Navamsa
The main chart, called the Rashi chart or D1, is only the first layer of a full Kundli. Vedic astrology also uses divisional charts, called vargas, that zoom into a specific area of life by dividing each sign further. The most important of these is the Navamsa, or D9 chart, which splits every sign into nine parts and is read closely for marriage, partnership, and the underlying strength of each planet. A planet that looks weak in the main chart but strong in the Navamsa is treated very differently from one that is weak in both, so astrologers often glance at the D9 before drawing conclusions. Other common divisions include the Dashamsha, or D10, for career and public life, and the Dwadashamsha, or D12, for parents and heritage. You do not need every varga to read a Kundli, but the Navamsa is worth knowing about, and it is a big reason serious matchmaking looks past the main chart alone.
Panchang: The Five Limbs of Your Birth Day
Alongside the chart, a traditional Kundli is often printed with the Panchang, the Vedic almanac of the day you were born. Panchang means five limbs, and it records five qualities of time: the Tithi, or lunar day, based on the angle between the Sun and the Moon; the Vara, or weekday; the Nakshatra the Moon occupies; the Yoga, a value combined from the Sun and Moon positions; and the Karana, which is half of a Tithi. These five are used to judge auspicious timing, which is why families consult a chart and a Panchang together when choosing a date for a wedding, a housewarming, or a naming ceremony. Your birth Panchang is a snapshot of those five values at the moment you arrived, and it sits naturally beside the rest of your Kundli.
Reading Your Kundli Respectfully
A Kundli belongs to a tradition thousands of years old, and it rewards being met on its own terms rather than read as a set of fixed predictions. Nothing in a chart is a sentence. A demanding Dasha, a Manglik flag, or a modest matchmaking score describes a tendency within the tradition, not a fact about your future, and every school of Jyotish also carries remedies, balancing factors, and honest disagreement. Read your Kundli as a mirror for thinking about your life, a thread back to family and heritage, and a prompt for reflection, and hold the harder placements lightly. That is both the healthiest way to use a chart and the way most thoughtful astrologers treat one in practice.
How This Kundli Calculator Works, in Plain Language
Under the hood, building your Kundli is an astronomy problem followed by a lookup problem. First the tool converts your birth date, time, and place into a precise moment in universal time, using the coordinates and time zone of your birthplace. Then it computes where every graha sat in the sky at that instant, using a high precision ephemeris, and switches that calculation into sidereal mode so the results match the Vedic zodiac.
From those raw positions the tool subtracts the Lahiri ayanamsa to land each planet in its sidereal sign and degree, works out the Lagna from the time and latitude, and assigns each planet to a house. It measures the Moon's longitude to find your Rashi and your Nakshatra, then uses the Nakshatra lord and the Moon's progress to lay out your Vimshottari Dasha. Finally it checks the position of Mars for Mangal Dosha and, if you entered a second person, runs the Ashtakoot scoring. Every step is deterministic, so the same birth details always yield the same Kundli.
How to Use the Tool
Using it takes under a minute. Enter your date of birth. Enter your time of birth as exactly as you can, ideally to the minute from a birth record, since the Lagna depends on it. Enter your place of birth and pick it from the list so the coordinates and time zone are set correctly. Then generate the chart.
Your Kundli appears right away, with the chart drawn in your chosen style and panels for the planetary positions, the Rashi and Nakshatra, the Dasha timeline, and the Manglik check. To match two charts, switch to the matching view and enter a second set of birth details. You can generate as many charts as you like, compare styles, and adjust a birth time to see how the ascendant shifts, all without any limit or login.
How to Read Your Kundli
Start with the big three. Find your Lagna to see your rising sign and the frame of the chart, your Rashi for the emotional core, and your Sun sign for the outward self. Together those give a quick sketch before you go deeper.
Next, scan the grahas. Note which planets sit in which houses, since a planet expresses itself through the affairs of its house. Look at the seventh house for partnership themes, the tenth for career, and the fourth for home and roots. Then read your Nakshatra for a finer personality note and check where you are on the Vimshottari Dasha timeline, which points to the planetary flavor of your current chapter. Save the doshas and matchmaking for last, and hold them lightly. A Kundli rewards slow reading, and no single placement defines a person.
Who Uses a Kundli, and Why
Demand for a Kundli is enormous across India and the global Indian diaspora, and people come to it for many reasons. Parents often have a Janam Kundli cast at a child's birth and keep it for life. Families use Guna Milan when arranging or blessing a marriage. Individuals check their current Dasha before a big decision, look up an auspicious window for a wedding or a launch, or simply want to understand the chart their grandparents always referred to.
Others come out of pure curiosity, comparing their Vedic Rashi to the Western sign they already knew, or exploring their Nakshatra for the first time. Students of astrology use a calculator like this to check charts quickly while they learn. Whatever brings you here, the tool gives you the full picture without pushing you toward a paid consultation.
Your Birth Data Stays Private
Your birth details are personal, and this tool treats them that way. When you enter your date, time, and place of birth, that information is used to compute your Kundli directly in your browser. It is never uploaded to a server, never written to an account, and never sold or shared with a third party. There is no email field, because there is no reason to ask for one.
That design is deliberate. Since the entire calculation happens on your own device, there is no stored copy of your birth data sitting on a system somewhere waiting to be leaked, mined, or handed to an advertiser. You can generate a chart, read it, close the tab, and know that nothing followed you out the door.
The Full Reading, Free, With No Wall
Plenty of astrology sites will show you a slice of a Kundli and then ask for money or an email to see the rest. The chart loads, but the Dasha is locked, or the matchmaking score is blurred, or a button invites you to buy the real report. This tool takes the opposite approach. The complete Kundli is free and instant.
That means the whole chart, the full list of planetary positions, the Rashi and Nakshatra, the entire Vimshottari Dasha timeline with its sub periods, the Mangal Dosha status, and the full Guna Milan matchmaking breakdown all appear at once, at no cost. There is no sign up, no email capture, no trial, and no premium tier hiding the useful parts. What you see is the actual reading, not a preview designed to sell you something.
Instant, Unlimited, and Ready on Any Device
The tool responds the moment you enter your details. There is no queue, no processing wait, and no cap on how many charts you can build. Cast your own Kundli, then your partner's, then a friend's, then run a dozen matchmaking checks, all in one sitting, with no account and no throttle.
It runs on any device with a browser, so a phone, tablet, laptop, or desktop all work, and the layout adjusts to the screen you are on. Because the math runs locally once the page has loaded, your Kundli still generates if your connection drops or disappears. Load the page once on a train or a plane, and you can keep casting charts offline until you close it.
