KP Ruling Planets Calculator

Every astrologer has noticed it: a client arrives with a question on a particular day, at a particular hour, and the sky at that hour seems to know what is on their mind. Traditional prashna has always worked on this. Krishnamurti gave it a narrow, testable form. He took the planets ruling the moment — through the weekday, the Moon and the rising sign — and found that they repeat the significators of whatever matter is being judged.

That turned an intuition into a working instrument. A KP astrologer who has found three or four planets able to deliver a marriage in a birth chart does not have to guess which of their periods will do it. The ruling planets at the time of judgement pick out the ones that are live, and the others fall away. Where the ruling planets and the significators disagree entirely, the astrologer takes it as a warning to check the birth time, or the question.

This is also why the ruling planets change as you watch. They are not a property of your chart but of the moment, and a question judged in the morning and the same question judged in the evening can show different ruling planets. Both are right for their moment; KP simply asks you to judge once, and trust it.

The five are not equal. The Ascendant is the most personal point of the moment, and the nakshatra rising carries more weight than the sign, so the Ascendant's star lord leads. The Ascendant's sign lord follows, then the Moon's star lord, then the Moon's sign lord, and the day lord comes last because it holds for a whole day and says least about this particular moment.

Repetition counts for more than position. Five ruling planets drawn from seven possible lords often throw up the same planet twice, and a planet that rules the moment through two channels is stronger than any that appears once. When you compare the ruling planets with your significators, a repeated planet that is also a strong significator of the matter is the one to watch most closely.

A ruling planet moving backwards cannot deliver while it is retrograde. In KP practice such a planet is set aside when timing an event, and the answer is looked for among the others. If the matter depends heavily on the retrograde planet, the event is expected only after it turns direct — which gives a useful timing clue of its own.

The same caution applies one level down. A ruling planet in the star of a retrograde planet tends to bring delays or a matter that comes, goes and returns. The dashboard marks retrograde planets so you can see at a glance which ruling planets to hold back.
