House Revolve in KP and Nadi Astrology: Reading Any House as the Ascendant
23 October 2026
Every house in a birth chart can be read in two ways. It describes a matter in the native's own life, and it can also be treated as the starting point, or Ascendant, for a related person or topic. The 7th house, for example, describes partnership, and when you count the chart again from the 7th you get a view of the partner's side of the story. KP and Nadi astrologers call this the House Revolving System. This guide explains how the House Revolve function works in Astrometry Nadi/KP Astrology/Horary Software, what changes on screen and what deliberately stays the same.
What House Revolve actually does
House Revolve renumbers the houses of a chart that has already been calculated. You choose one natal house, and that house becomes house 1. Every other house is counted forward from it. Nothing else is recalculated: planetary longitudes, signs, nakshatras, star lords, sub-lords, cusp degrees and Vimshottari Dasha dates are exactly what the software produced for the original chart.
That is an important point. A revolved chart is not a new chart cast for another moment or another person. It is the same sky, read from a different starting house. If you need the relative's own birth chart and you have reliable birth details, create that chart separately.
How the numbers change
The rule is simple counting. If you choose house A as the Ascendant, natal house A becomes house 1, natal house A+1 becomes house 2, and so on around the zodiac. The table below shows the full mapping when the 7th house is chosen.
| Natal house | Revolved house (7th as Ascendant) |
|---|---|
| 7 | 1 |
| 8 | 2 |
| 9 | 3 |
| 10 | 4 |
| 11 | 5 |
| 12 | 6 |
| 1 | 7 |
| 2 | 8 |
| 3 | 9 |
| 4 | 10 |
| 5 | 11 |
| 6 | 12 |
So a planet in the native's 10th house reads as the 4th house from the 7th. With the 6th house chosen instead, the same 10th-house planet reads as house 5. You never need to do this arithmetic by hand: the software applies it to every house reference it renumbers.
Which house to choose
Traditional practice links particular houses with particular people. The list below is a common reference point, not a fixed law; schools differ on some relationships, so follow the convention you have studied.
3rd house - younger siblings
4th house - mother
5th house - first child
7th house - spouse or business partner
9th house - father, in many traditions
11th house - elder siblings
The same idea of reading a house from another house is the basis of Bhavat Bhavam. If that principle is new to you, the Bhavat Bhavam software guide and the Bhavat Bhavam software are a good companion to this article.
Using House Revolve in a birth chart, step by step
Calculate the chart first. Enter the birth details in the Nadi/KP software and check the date, time, place and ayanamsa before doing anything else. House Revolve cannot correct a wrong birth time; it only reads the existing chart from another house.
Open House Revolve. In the Charts section, click House Revolve. The House Revolving System box asks you to select the house number to be used as the Ascendant.
Pick a house from 1 to 12 and press OK. The Lagna Chart and the Nirayana Cusps chart turn so the chosen house sits in the first position.
Read the renumbered tables. Planetary Placements, the significator tables and the Vimshottari Dasha table now show house numbers counted from your chosen house. A small red note on each of these sections tells you which house is being used, so you always know which view you are reading.
Return to the natal view. Click Reset to natal to bring every section back to the original houses.
What follows the chosen house, and what does not
| Renumbered by House Revolve | Unchanged |
|---|---|
| Lagna Chart and Nirayana Cusps | Planetary degrees, signs and nakshatras |
| House column in Planetary Placements | Star lords and sub-lords |
| Houses occupied, owned and signified in the significator tables | Cusp degrees |
| Houses shown beside each lord in the Dasha table | Dasha, Bhukti and Antara dates |
Some sections of the software still show the original natal houses, including Nadi Chains, the Planet Influence Graph, Predictions and Ruling Planets. Keep that in mind when you move between sections, and use the red House Revolve note as your guide.
Because Dasha dates do not change, a revolved view lets you ask a focused question: during this period, which houses counted from the chosen house does the running lord signify? That is a reading layer on top of the same timeline, which is why the dates must stay fixed. If dates ever differ between two of your sessions, the cause will be in the birth details or settings, not in House Revolve; the Dasha dates checklist explains what to compare.
House Revolve in Horary Prashna
The same function is available in the Horary Prashna report. After you create a Prashna chart, a House Revolve button sits beside the horary charts. Both charts and the cuspal sub-lord table follow the chosen house in the same way.
There is one deliberate difference. The houses of fruition and denial for a question are counted from the Prashna Lagna, so turning the chart does not change the answer to the question. The highlighted rows stay on the same cusps after you revolve the view. This keeps a convenient study view from silently altering a verdict.

A worked outline
Suppose you want to study the partner's side of a marriage question in a native's chart. Choose the 7th house as the Ascendant. The native's 7th now reads as house 1, the native's 10th reads as house 4, and the native's 1st reads as house 7. In the significator tables you can now see which planets connect to the 1st, 7th and other houses counted from the partner's starting point, and in the Dasha table you can see which of those houses each running lord touches. The planets, their stellar lords and the period dates are identical to the natal view; only the house numbering has moved.
This is an outline of the method, not a prediction. Combine it with the promise-first approach explained in KP Astrology: Houses, Significators and Event Timing, and with the significator basics in KP significators explained.
Common mistakes
Forgetting which view is on screen. Always check the red House Revolve note before copying a house number into your notes.
Treating the revolved chart as the relative's own chart. It is a derived view from the native's chart. A separate birth chart, where available, is a different and independent source.
Expecting new planetary positions or dates. House Revolve never recalculates them. If you need a different moment, calculate a new chart.
Mixing natal and revolved numbers in one judgement. Decide which starting house you are reading from, and stay with it until you press Reset to natal.
Frequently asked questions
Does House Revolve change the ascendant degree?
No. The original Ascendant and every cusp degree are kept. The chosen house is simply numbered as house 1 for reading purposes.
Is the PDF affected?
The downloaded report follows the view that is on screen, so reset to natal first if you want the standard report.
Can I use it to make claims about another person?
Use it as a study aid and be careful how you communicate any reading about someone who has not asked for one. Astrological interpretation is a traditional practice and should not be presented as certain fact about a third party.
