Jathagam and Jathakam: The Complete Guide to Your South Indian Birth Chart

Jathagam (Tamil) and jathakam (Telugu, Malayalam, Kannada) are South Indian names for the Vedic birth chart. It is the same chart that is called kundli in the north. It is drawn in the South Indian square format, with the signs fixed and the lagnam marked. To make one online, enter your date, time and place of birth. You will get your rasi chart, navamsa (amsam) chart, natchathiram and dasa-puthi periods.

In Tamil Nadu, Andhra Pradesh, Telangana, Kerala and Karnataka, the birth chart has its own names and its own look. "Jathagam Tamil," "jathakam in Telugu," "online jathagam" and "online jyothisham" together get several lakh searches a month. Families use the jathagam for naming, education, career advice and, above all, marriage matching through porutham.

This guide explains everything. You will learn what a jathagam is, how to make one online, how to read the South Indian chart, the Tamil, Telugu and Malayalam terms you will see, how dasa-puthi works, and how jathagam matching (10 porutham) is different from North Indian Guna Milan.

Jathagam, Jathakam, Kundli: Same Chart, Different Names

All of these are the same Vedic (sidereal) birth chart. The planets, signs, houses and nakshatras are the same. The main differences are how the chart is drawn and which terms are used. If you have read our kundli guide, everything there applies. This guide adds the South Indian side.

How to Make Your Jathagam Online (Free)

1. Open a trusted jathagam / kundli calculator, such as the free Vedaz birth chart tool.
2. Enter your date of birth.
3. Enter your exact time of birth, with AM or PM.
4. Enter your place of birth and pick the right town, so the latitude, longitude and time zone are correct.
5. Choose the South Indian chart style if the tool offers it.
6. Generate the chart. You will get your rasi chart, navamsa chart, lagnam, rasi, natchathiram with padam, and dasa-puthi table.
7. Save it for matching and future consultations.

What makes an online jathagam accurate? It needs exact planet data (Vedaz uses the Swiss Ephemeris), the right ayanamsa (Lahiri, India's official standard), and the right time zone and coordinates. "Jathakam based on date of birth and time" is exactly right, because both are needed for an accurate lagnam and dasa balance.

Vakya vs Thirukanitha: Why Tamil Jathagams Sometimes Differ

Tamil astrology has one special twist. Two calculation methods are in use:

• Vakya panchangam is the older, traditional system, based on classical verse formulas (vakyas). Many temples and traditional families still use it.
• Thirukanitha (Drik) panchangam is the modern system, worked out from the real positions of the planets.

The two can differ by a few hours in tithi and nakshatra timings. Sometimes they differ by a whole natchathiram, or even a rasi, for a planet near a boundary. That is why a jathagam written by a family astrologer using Vakya may not match an online jathagam exactly. Vedaz uses exact astronomical (Thirukanitha-style) calculation through the Swiss Ephemeris. If your old handwritten jathagam is different, check the birth details first, and then ask which system was used.

Reading the South Indian Chart

The South Indian chart is a square of 12 boxes around an empty centre. Unlike the North Indian diamond, the signs never move. Each box always holds the same rasi. You find the lagnam (ascendant) by looking for the box marked "La," "Lag," "ல" or with a diagonal line.

The fixed layout (clockwise from top-left):

How to read it:

1. Find the box marked as lagnam. That is your 1st house.
2. Count clockwise to find the 2nd, 3rd ... 12th houses.
3. Read the planet short forms in each box.

Planet Names You'll See in a Jathagam

You may also see Mandi / Gulikan, which is a sub-planet (upagraha) used a lot in Kerala astrology.

Key Jathagam Terms Explained

• Lagnam (லக்னம் / లగ్నం): The ascendant, which is the rasi rising at birth. It sets the 1st house and the overall direction of life.
• Rasi (ராசி / రాశి): Your Moon sign. It is used for daily rasi palan and Sade Sati (Ezharai Sani in Tamil).
• Natchathiram / Nakshatram: Your birth star, the Moon's lunar mansion. See our nakshatras guide.
• Padam: The quarter (1–4) of your natchathiram.
• Rasi chart: The main birth chart (D1).
• Amsam / Navamsam chart: The navamsa (D9) chart. It is key for marriage and for the strength of planets.
• Dasa-Puthi (Tamil) / Dasa-Antardasa (Telugu): Planetary periods and sub-periods (Vimshottari system).
• Kendram: The angular houses (1, 4, 7, 10). Thirikonam: The trinal houses (1, 5, 9).
• Ucham / Neecham: Exalted / weak (debilitated).
• Vakram: Retrograde.
• Asthangam: Combust (too close to the Sun).
• Sevvai dosham / Kuja dosham: Manglik dosha.
• Rahu-Kethu dosham / Sarpa dosham: Rahu or Ketu in houses that matter for marriage.
• Ezharai Sani: Sade Sati. Ashtama Sani: Saturn in the 8th house from the Moon. Ardhashtama Sani: Saturn in the 4th house.

Dasa-Puthi: The Timeline in Your Jathagam

Every jathagam includes a dasa-puthi (Tamil) or dasa-antardasa (Telugu) table. It is the Vimshottari dasha system:

Your first dasa is ruled by the lord of your birth natchathiram. The dasa balance at birth (irupu dasa in Tamil) shows how much of it was left when you were born. Your current dasa and puthi tell you which planets' themes are most active in your life right now.

Jathagam Porutham: South Indian Marriage Matching

In the south, marriage matching is usually done through porutham (Tamil) or jathakam matching (Telugu). Instead of the North Indian 8-koota Guna Milan, the traditional method checks 10 poruthams:

Many families treat Rajju and Vedhai as a must, and look for a minimum number of the other poruthams. Then the full jathagams are compared for Sevvai dosham, Rahu-Kethu dosham, the 7th house and the dasa running at the time of marriage.

As with all doshas, cancellations matter. For example, Sevvai dosham is traditionally cancelled when both partners have it, or when Mars is in its own or exalted sign, among other conditions. A good astrologer always checks these before giving advice. You can run a free match using kundli matching, which shows the Ashtakoota score with dosha cancellations. You can also read our kundali matching guide to see how it overlaps with porutham.

Telugu Jathakam for Marriage

Telugu families usually look at:

• Rasi and nakshatra match (similar to porutham).
• Kuja dosham and its cancellations.
• Gunas. Many Telugu astrologers also use the 36-point Ashtakoota.
• Muhurtham. The wedding time is picked from both jathakams and the panchangam - panchang.

Malayalam Jathakam and Kerala Astrology

Kerala has a rich astrology tradition, including Prasna Marga (horary astrology) and the use of Gulikan (Mandi). Kerala jathakams often include detailed palm-leaf style predictions and use the Malayalam (Kollam) calendar alongside the Vedic chart. Papasamyam is a special Kerala matching method that compares the "malefic points" in both charts.

How to Read Your Jathagam: A Simple 6-Step Method

1. Find your lagnam and its lord. Where is the lagnadhipathi placed?
2. Find your rasi and natchathiram.
3. Read the planets in each house, counting clockwise from the lagnam.
4. Check ucham, neecham, vakram and asthangam for each planet.
5. Look at the amsam (navamsa) chart, especially for marriage and the strength of the 7th lord and Venus.
6. Note your current dasa-puthi and look at where those planets sit.

If you would like help, you can ask Vedaz, the Vedaz AI astrologer to explain your chart in plain language, including the Tamil or Telugu terms.

Common Questions About Old vs New Jathagams

"My handwritten jathagam shows a different natchathiram." Check the birth time first, because AM and PM mix-ups are common. Then check whether the old one used Vakya calculation. Births near a natchathiram boundary are most affected.

"My lagnam is different." The lagnam changes about every two hours, and it is very sensitive to birth time and place. A difference of a few minutes can change it if you were born near a boundary.

"The dasa balance doesn't match." Dasa balance depends on the exact Moon degree. Small differences in calculation can shift it by months.

Jathagam for Naming, Education and Muhurtham

A jathagam is used at many points in life, not just for marriage:

• Namakaranam (naming ceremony): Families often choose a name that starts with the syllable linked to the baby's natchathiram padam. Our nakshatras guide lists the syllables for every padam.
• Aksharabhyasam / Vidyarambham (starting education): Many Tamil, Telugu and Kerala families begin a child's education, often on Vijayadashami, at a muhurtham chosen with the jathagam and panchangam.
• Career decisions: The 10th house, its lord and the current dasa-puthi are read for job changes, business launches and government-service plans. Astrology can suggest timing, but results come from preparation.
• Griha pravesam (house-warming): The muhurtham is picked from the family members' natchathirams and the day's panchangam, avoiding Rahu kalam, Yamagandam and inauspicious tithis.
• Annual review: Many families consult an astrologer at the Tamil or Telugu new year (Puthandu or Ugadi) to review the year's transits, especially Guru peyarchi (Jupiter transit) and Sani peyarchi (Saturn transit). These are major events in South Indian astrology.

Tamil and Telugu Words for Transits and Timing

Jathagam Myths, Busted

"A bad jathagam means a bad life." No chart is purely "good" or "bad." Every jathagam has strengths, challenges and good and bad timing.

"Sevvai dosham ruins marriages." Sevvai dosham is very common and is often cancelled. It should always be judged with the full chart.

"Ezharai Sani is a curse." Sade Sati is a period of responsibility and growing up, and many people achieve lasting success during it.

"If porutham fails, the marriage is impossible." Porutham points to areas to look at. Experienced astrologers read the full jathagams, and the couple's understanding matters most.
