Arudha Lagna Calculator

How the world sees you — the reflection your chart casts, not the self behind it. Calculate your Arudha Lagna with the full Jaimini method, with the working shown.

Arudha Lagna is ascendant-based, so an accurate birth time matters. Your birth details are used only to calculate — nothing is saved, and no account is needed.

What is Arudha Lagna?

In Jaimini astrology, the word arudhameans “mount” or “reflection.” The Arudha Lagna (AL) is not your real self — it is the reflection of your self in the mirror of society. Where the Lagna (ascendant) describes who you actually are, the Arudha Lagna describes the image the world receives: your public perception, reputation, visibility, and worldly status.

This is why two people with the same ascendant can be experienced so differently by the world. The Lagna is the lamp; the Arudha Lagna is the shadow it throws on the wall that others see.

How to calculate Arudha Lagna

The Arudha Pada of any house is found in three steps:

  1. Note the house and the planet that rules it (for the Arudha Lagna, this is the Lagna and the Lagna lord).
  2. Count the number of signs from the house to the sign occupied by its lord.
  3. Count that same number of signs forward again from the lord. The sign you reach is the Arudha.

Worked example. Libra ascendant; the Lagna lord Venus sits in the 5th house (Aquarius). Count Libra → Aquarius = 5 signs. Count 5 signs forward from Aquarius → Gemini. Gemini is the 9th from the Lagna, and not the 1st or 7th, so no exception applies: the Arudha Lagna is Gemini.

The exception rules

An Arudha can never sit in the 1st or the 7th sign from its own house — those positions are too close to the source to form a true reflection. When the calculation lands in the 1st or 7th, the 10th sign from that point is taken as the Arudha instead (Brihat Parashara Hora Shastra, Chapter 29). Many quick online calculators skip this rule and return a wrong Arudha; this calculator applies it automatically and tells you when it fired.

Arudha Padas: the image of every house

Just as the Lagna has its Arudha, every house has one. These bhava padas(A2–A12) describe how each area of life is perceived, not only how it functions: A2 the image of wealth, A4 of home, A7 (the Darapada) of partnership, A9 of fortune and belief, A10 of career and public work, A11 of gains. The calculator above lists all twelve for your chart.

Frequently asked questions

What is Arudha Lagna?

Arudha Lagna (AL) is the 'image' of the ascendant — how you appear to the world, your public perception and worldly status. In Jaimini astrology it is the reflection of the self in the mirror of society, which can differ sharply from who you feel you are inside (the Lagna).

How is Arudha Lagna calculated?

Find the Lagna and its ruling planet. Count the number of signs from the Lagna to the sign holding the Lagna lord. Then count that same number of signs forward from the lord. The sign you land on is the Arudha Lagna — unless an exception applies.

What is the difference between Lagna and Arudha Lagna?

The Lagna is your real self and inner orientation. The Arudha Lagna is the projected self — the persona and reputation others perceive. When they coincide, how you are seen matches who you are; when they diverge, you are routinely misread.

What are the Arudha Lagna exception rules?

An Arudha can never rest in the 1st or 7th sign from its own house. If the calculation lands there, the 10th sign from that point is taken instead (BPHS, Chapter 29). Good Arudha calculators apply this automatically — many simple ones get it wrong.

What are Arudha Padas?

Each of the twelve houses has its own Arudha (image) — A2 is the image of wealth, A7 (the Darapada) the image of partnership, A10 the image of career, and so on. Together they describe how each area of life is perceived, not only how it actually is.

Why do people perceive me differently from who I am?

Because the world reacts to your Arudha Lagna, not your Lagna. The image your chart projects — and the planets that occupy and aspect it — shape first impressions and reputation, which is why the perceived self and the real self can quietly pull apart.

From image to meaning

The Arudha Lagna tells you the frame the world perceives. What it actually means for you — what strengthens or distorts that image, where you are most often misread, and when public visibility activates in your timeline — depends on the whole chart working together.
