India is a big country with distinct regional traditions, and the way people draw birth charts varies by geography. A family in Chennai draws the chart differently from a family in Delhi, and a family in Kolkata has their own style too. I have sat in rooms where two astrologers argued about chart formats like people argue about text editors. Vi vs Emacs, but with more Sanskrit.
Here is the thing though: all three formats contain the exact same astronomical information. The planets are in the same signs. The houses represent the same life areas. The ascendant is the same degree. It is like writing the same phone number with dashes, dots, or spaces between the digits. The number does not change. Only the presentation does.
If you followed the previous post on reading North Indian charts, you already know one format well. This post introduces the other two and shows you how they relate. By the end, you should be able to look at any Indian birth chart and at least orient yourself.
Astrology in India developed over thousands of years across a subcontinent with dozens of languages and scholarly traditions. The major texts were written in different regions and eras, and local practitioners adapted the visual format to suit their conventions.
The North Indian style traces its lineage primarily to the Parashara tradition, which is dominant in the Hindi-speaking belt. The South Indian style has strong connections to the Varahamihira tradition and the Dravidian scholarly lineage. The East Indian style, sometimes called the Surya Chakra, evolved from the astronomical traditions of Bengal and Odisha.
None of these styles is “better” or “more accurate.” They all encode identical data. Saying one is superior to another is like saying Celsius is more accurate than Fahrenheit. They are measurement systems, not truth claims.
I find the map analogy works well here. A Mercator projection and a Peters projection show the same Earth. They distort different things. They are useful for different purposes. But the actual geography does not change based on which map you use. Same idea with chart styles.
Since we covered this in detail in the last post, I will keep this section brief as a refresher.
Shape: Rectangle divided by diagonal lines, creating a diamond-in-rectangle pattern with 12 sections.
What is fixed: House positions. House 1 is always at the top diamond. House 4 always on the left. House 7 always at the bottom. House 10 always on the right.
What rotates: Zodiac signs. The sign numbers change based on the person’s Lagna (ascendant). Your Lagna sign goes into House 1, and the rest fill in sequentially counter-clockwise.
Direction: Counter-clockwise.
Lagna indicator: The top diamond section IS the Lagna. Always. No marker needed because the position itself tells you.
Where it is popular: Uttar Pradesh, Madhya Pradesh, Rajasthan, Gujarat, Punjab, Haryana, Himachal Pradesh, and Nepal. Basically the entire Hindi belt and surrounding areas.
Practical advantage: Because houses are fixed, you can instantly see house relationships. Want to check the 7th house from any house? Just look at the opposite section. Trines (houses 1, 5, 9) form a visible triangle on the chart. This makes it easy to do quick visual analysis of house relationships.
Practical disadvantage: Signs move around from chart to chart. If you are comparing transits to a birth chart, you need to mentally track which sign is where. That takes a bit more effort.
This is where things look completely different. Forget the diamonds and triangles. The South Indian chart is a grid.
Shape: Imagine a 4x4 grid of squares. Now remove the 4 squares in the center. What you have left is 12 cells arranged around the perimeter of the grid, forming a rectangular frame. That is the South Indian chart.
What is fixed: Zodiac sign positions. This is the opposite of the North Indian approach. In the South Indian chart, each cell permanently represents a specific zodiac sign.
The sign layout starts with Pisces in the top-left corner, then moves clockwise:
| Pisces (12) | Aries (1) | Taurus (2) | Gemini (3) |
|---|---|---|---|
| Aquarius (11) | Cancer (4) | ||
| Capricorn (10) | Leo (5) | ||
| Sagittarius (9) | Scorpio (8) | Libra (7) | Virgo (6) |
The signs are always in these positions. Every South Indian chart you will ever see has Pisces in the top left and Aries next to it. This never changes.
What rotates: House numbers. The Lagna sign’s cell becomes House 1, and then you number the houses clockwise from there.
Direction: Clockwise. Yes, opposite from the North Indian chart.
Lagna indicator: The cell containing the Lagna sign gets a diagonal line drawn across it (usually from one corner to the opposite corner). This slash mark tells you “this is where House 1 starts.”
Where it is popular: Tamil Nadu, Kerala, Karnataka, Andhra Pradesh, Telangana, and parts of Maharashtra. The entire South Indian astrological tradition uses this format.
Practical advantage: Since signs are fixed, tracking planetary transits is much easier. If you know Saturn is currently in Aquarius, you just look at the Aquarius cell (always in the same position) and mentally compare it to the birth chart positions. For people who follow daily or weekly transits, this is a real time-saver.
Practical disadvantage: House relationships are not as visually obvious. To find the 7th house from any given house, you need to count six cells clockwise. In the North Indian chart, you just look at the opposite position. This is a minor annoyance once you are used to the format, but it is a real barrier when you are learning.
Say the Lagna is Leo (sign 5). In the South Indian chart, you find the Leo cell (right side, second from bottom in the standard layout). Draw a diagonal slash through it. That is House 1.
Now count clockwise from Leo: Virgo becomes House 2, Libra becomes House 3, Scorpio becomes House 4, and so on around the grid. The house numbers wrap around the perimeter following the fixed sign positions.
The planets go into whichever cell corresponds to the sign they occupy. Moon in Scorpio? Put “Mo” in the Scorpio cell. Jupiter in Pisces? Put “Ju” in the top-left cell. You do not need to figure out which house the sign falls in to place the planet. Just find the sign’s cell and write it in. The house number can be determined afterward.
This one is less commonly seen outside eastern India, but it has its own elegance.
Shape: Start with a 3x3 grid (9 squares). Now draw diagonal lines from the four corners of the outer grid to the center point where the inner grid lines cross. This creates a pattern where the 4 cells at the center of each edge become rectangles, and the 4 corner cells plus the 4 edge sections get split into triangles. The result is 12 sections total.
Honestly, it looks a bit like the North Indian chart’s cousin. There are triangles and rectangular sections, but the proportions and arrangement are different.
What is fixed: Zodiac sign positions, like the South Indian chart. Aries is at the top center, and signs flow counter-clockwise: Aries (top), Taurus (upper left), Gemini (left), Cancer (lower left), Leo (bottom left), Virgo (bottom), Libra (bottom right), Scorpio (right), Sagittarius (upper right), and the remaining signs filling in the pattern.
Wait, I should be more precise. The exact arrangement varies slightly between sources, but the most common version places Aries at the top and goes counter-clockwise around the chart. The key point is that sign positions are fixed.
What rotates: House numbers, just like in the South Indian chart.
Direction: Counter-clockwise for sign flow. Counter-clockwise for house numbering from the Lagna.
Lagna indicator: Similar to the South Indian chart, the Lagna cell is marked with a diagonal line or highlighted.
Also called: Surya Chakra, Bengali chart, or sometimes Odisha chart. You might hear “Purbi” (Eastern) style as well.
Where it is popular: West Bengal, Odisha, Assam, and parts of Northeast India. Also used in some parts of Bihar and Jharkhand.
Practical advantage: It is compact and shows sign relationships clearly. The fixed-sign approach gives it the same transit-tracking benefit as the South Indian style.
Practical disadvantage: It is the least widely documented of the three styles. Finding learning materials specifically about the East Indian format can be frustrating. Most astrology courses and textbooks focus on North or South Indian styles.
Fixed house positions, rotating signs. The diamond pattern at top is always House 1. Signs fill in counter-clockwise. Most popular in North India, parts of Western India, and Nepal.
Switch between the three styles in the interactive comparison above. Notice how the same planets appear in corresponding positions in each format. The data is identical. Only the visual arrangement changes.
Here is a comparison table that summarizes the structural differences:
| Feature | North Indian | South Indian | East Indian |
|---|---|---|---|
| What is fixed | House positions | Sign positions | Sign positions |
| What rotates | Zodiac signs | House numbers | House numbers |
| Direction | Counter-clockwise | Clockwise | Counter-clockwise |
| Shape | Diamond in rectangle | Square grid (perimeter) | Grid with diagonals |
| Lagna marker | Always top diamond (no marker needed) | Diagonal slash in Lagna sign’s cell | Diagonal slash or highlight |
| House 1 location | Always top center | Wherever the Lagna sign is | Wherever the Lagna sign is |
The most important distinction is the first row. North Indian charts fix the houses and move the signs. South and East Indian charts fix the signs and move the houses. This single difference explains almost everything else about how the three formats behave.
Since all three styles contain the same data, converting between them is straightforward once you understand the principle. The core mapping is always:
House X contains Sign Y contains Planets Z
That three-part relationship is the same regardless of which chart style you use. If you know the Lagna sign, you can reconstruct any chart in any style.
Let me walk through a conversion. Say you have this information:
North Indian: House positions are fixed. Leo goes into House 1 (top). Count forward: Virgo in House 2, Libra in House 3, Scorpio in House 4, Sagittarius in House 5, Capricorn in House 6. So Saturn sits in the House 6 position (bottom-left triangle).
South Indian: Sign positions are fixed. Find the Capricorn cell (left side, second from bottom). Write “Sa” in it. Capricorn is always in that cell. To figure out which house number it is, count clockwise from Leo (which is House 1): Virgo=2, Libra=3, Scorpio=4, Sagittarius=5, Capricorn=6. Same house number, different visual location on the chart.
East Indian: Sign positions are fixed. Find wherever Capricorn falls in the East Indian layout. Write “Sa” there. Count from Leo to determine it is the 6th house. Same answer again.
Three different visual locations for Saturn on the chart. Same underlying reality: Saturn is in Capricorn in the 6th house.
I get asked this a lot, and my honest answer is: learn whatever your family uses first.
If your parents or grandparents consult astrologers who use the North Indian chart, start there. You will be able to look at your family’s existing charts and understand them immediately. That practical connection matters more than any theoretical advantage.
If you do not have a family tradition to draw from, here are some rough guidelines:
Start with North Indian if: You want house relationships to be visually obvious. You are comfortable with signs moving around. You plan to study astrology primarily through Hindi-language resources.
Start with South Indian if: You want to track transits easily. You prefer a grid layout that feels orderly and systematic. You are learning from Tamil or Kannada astrology teachers.
Start with East Indian if: You are from Bengal, Odisha, or the Northeast, and want to read charts in your family’s traditional format.
For what it is worth, most astrology software (including KundliGPT) can display charts in all three styles. So you are not locked in. I learned North Indian first because that is what my family used, but I have come to appreciate the South Indian format for transit analysis. These days I switch between them depending on what I am doing.
The analogy I keep coming back to is language. A bilingual person does not think in one language and translate to the other. They just think in whichever language fits the situation. Chart styles work the same way eventually. You stop “converting” and start just reading.
There are other chart formats you might encounter. The Western circular chart (wheel format) is used by some modern Indian astrologers who trained in Western astrology. There are also regional variations within the three major styles, like slight differences in how the East Indian chart arranges its triangles.
Some software shows “KP charts” which follow the Krishnamurti Paddhati system and can look different from traditional formats. And Jaimini-tradition astrologers sometimes use chart formats that emphasize sign-based aspects rather than house-based ones.
Do not worry about these for now. Master one of the three major styles, get comfortable with it, and the rest will come naturally when you need it.
The data inside the chart is more interesting than the chart format itself. Now that you can read all three major Indian chart styles (or at least recognize them and understand their logic), it is time to go deeper into how planets interact with each other.
In the next post, we will cover planetary aspects, called Drishti in Sanskrit. This is how planets influence houses they are not even sitting in, and it is one of the things that makes Vedic chart interpretation so layered. A planet in the 1st house can affect the 5th, 7th, and 9th houses simultaneously. How? That is next.
