This calculator works out two of the most useful arudha padas from your date, time, and place of birth: the Arudha Lagna, which is the public image the chart projects, and the Upapada Lagna, which is read for marriage and the first spouse. It returns the sign of each, the lord of the Upapada, and the related points, all on sidereal positions with the Lahiri ayanamsha, the same configuration Jagannatha Hora uses, so the result matches the software.

How the Arudha Lagna and Upapada are worked out
An arudha pada is found by counting. You take a house, count to the sign its lord occupies, then count the same distance again from the lord. The sign you land on is the arudha of that house. The Arudha Lagna is the arudha of the first house, the ascendant, and the Upapada Lagna is the arudha of the twelfth. The idea behind it is that the arudha shows the reflection of a house, the way its matters appear to the world rather than the way they truly are.
Two classical adjustments apply. A pada should not fall in the same sign as the house it comes from, and it should not fall in the seventh sign from that house. When the count lands on either, the pada is shifted to the tenth sign from that position. The calculator applies these rules for you, so the Arudha Lagna and Upapada it shows already account for the exceptions, which is where most manual attempts go wrong.
Your Arudha Lagna, the image of the self
The Arudha Lagna, often shortened to AL, is how the world sees you, your reputation and the impression you make, which can differ a good deal from who you feel you are on the inside. Where the ascendant is the real self, the Arudha Lagna is the projected self, the public role. Reading the sign of your Arudha Lagna, along with the planets that sit in it and aspect it, describes the kind of image that tends to form around you. The full method and the sign-by-sign meanings are covered in the Arudha Lagna guide, and the calculator links you straight to the reading for your own sign.
Your Upapada Lagna, the significator of marriage
The Upapada Lagna, or UL, is the arudha of the twelfth house and is one of the main tools in Jaimini for looking at marriage and the first spouse. Its sign and its lord describe the character and circumstances of the partnership, and the planets influencing it colour how the marriage is experienced. The sign-by-sign detail, with how the Upapada pairs with the seventh house and the Darakaraka, is set out in the Upapada Lagna guide. Because the Darakaraka is the other half of the spouse picture in Jaimini, you can find yours with the chara karaka calculator and read the two together.
A word of care on the Upapada. Classical texts also look at the second sign from it as an indicator tied to the durability of the marriage, and the calculator shows that sign for completeness. This is an area to read gently and never in isolation. A challenging indication here is a prompt to pay attention, not a verdict on a relationship, and it has to be weighed against the seventh house, the Darakaraka, the running dasha, and the lived reality of the people involved. Treat the whole of the marriage analysis as a description of tendencies you can work with, not as a prediction of fixed events.
Reading the two together
The Arudha Lagna and the Upapada answer different questions, one about how you are seen and one about partnership, so they are usually read alongside the rest of the chart rather than on their own. Both belong to the wider Jaimini system, and if you want the full set of movable significators that sit behind them, the Chara Karaka guide lays them out. To see your complete birth chart with the divisional charts, dasha, and yogas in one place, the kundali calculator casts everything.
Method and accuracy
Positions are sidereal, calculated on the Lahiri ayanamsha with whole-sign houses, the standard settings in Jagannatha Hora, so the Arudha Lagna and Upapada this calculator shows match what the software gives for the same birth data. The two exception rules for pada placement are built in. Because both padas are tied to the ascendant and the houses, an accurate birth time matters, so if your time is approximate, hold the results lightly and consider having the chart rectified before leaning on them.
On how to use this, the arudha padas describe perception and tendency, the image that forms and the shape a partnership tends to take. They are a tool for reflection and study, and they say nothing on their own about timing, which belongs to the dasha. Read them as part of a fuller picture rather than as a standalone answer.
Frequently asked questions
What is the Arudha Lagna?
The Arudha Lagna is the arudha pada of the ascendant. It represents the public image of the chart, how a person is seen and the reputation that forms around them, which can be quite different from the inner self shown by the ascendant itself.
What is the Upapada Lagna?
The Upapada Lagna is the arudha pada of the twelfth house. In Jaimini astrology it is one of the main points read for marriage and the first spouse, with its sign and lord describing the character of the partnership.
How is the Arudha Lagna calculated?
You count from the first house to the sign its lord occupies, then count the same distance again from the lord. The sign you reach is the Arudha Lagna, after applying the two exception rules that prevent it landing in the same sign as the ascendant or the seventh from it. The calculator does this automatically.
What does the Arudha Lagna tell me?
It describes the image others hold of you rather than your inner nature. The sign of the Arudha Lagna, and the planets in and aspecting it, suggest the kind of reputation and public impression that tends to gather around you over time.
What does the Upapada say about marriage?
It points to leanings rather than fixed outcomes. The sign and lord of the Upapada, read with the seventh house and the Darakaraka, describe the character and circumstances of the marriage. It is best read as a description of tendencies, weighed against the whole chart, not as a guarantee.
Is the Arudha Lagna the same as my ascendant?
No. The ascendant is the rising sign and represents the real self. The Arudha Lagna is a separate point, the arudha of the ascendant, and represents the projected image. They can occasionally fall in related signs, but they are different points with different meanings.
What is the second sign from the Upapada?
Classical Jaimini reads the sign after the Upapada as an indicator connected to the durability of the marriage. It should be read with great care and never on its own, since a difficult signal there is a prompt for awareness rather than a conclusion about any relationship.
Which ayanamsha and house system does this use?
It uses the Lahiri ayanamsha with sidereal longitudes and whole-sign houses, the standard setup in Jagannatha Hora, which is why the Arudha Lagna and Upapada it shows match the software for the same birth details.
Can the Arudha Lagna and the ascendant share a sign?
The exception rules are designed to stop the Arudha Lagna falling in the ascendant sign itself, so in practice they usually differ. When the raw count would place it there, it is moved to the tenth sign from that position.
What is the darapada, and is it the same as the Upapada?
The darapada is the arudha of the seventh house and is another point read for relationships and partnership. It is different from the Upapada, which is the arudha of the twelfth. Some practitioners read both, the Upapada for marriage and the darapada for the partner as experienced, alongside the Darakaraka.
