⟶Chart Ruler Calculator
In chart ruler astrology, the planet that rules your rising sign steers the rest of your chart. Enter your birth time and place to find yours, along with its sign and house.
How it's found
Each sign has a ruling planet, the one whose style it shares. Your chart ruler is the ruler of your rising sign, using the traditional rulers: Mars for Aries and Scorpio, Venus for Taurus and Libra, Mercury for Gemini and Virgo, the Moon for Cancer, the Sun for Leo, Jupiter for Sagittarius and Pisces, and Saturn for Capricorn and Aquarius. Modern astrology adds Pluto to Scorpio, Uranus to Aquarius and Neptune to Pisces as a second layer. The tool gives the traditional ruler, and needs an exact birth time and place.
Its sign and house
The ruler's sign is the style you steer with, and its house is the area of life you keep steering toward. Houses are whole sign houses, so your rising sign is the 1st house, and another app using Placidus may show a house one over. A Gemini rising with Mercury in Pisces, in the 10th house, steers by imagination and intuition, and aims it at work and public life.
Questions
Do I need my birth time?
Yes. The chart ruler depends on your rising sign, and the rising sign needs an exact time and place.
Can my chart ruler be the Sun or the Moon?
Yes. Leo rising is ruled by the Sun and Cancer rising by the Moon.
Why does the tool use traditional rulers?
Each rising sign has one traditional ruler, which keeps the answer clear. For Scorpio, Aquarius and Pisces rising, the modern co-ruler is a second layer you can read alongside it.
