Rahu and Ketu calculator
Rahu and Ketu are the two points where the Moon's path crosses the Sun's. Vedic astrology reads them as the direction you are growing in and the skills you already carry.
Result
Where Rahu pushes you to grow and what Ketu says you already know.
- RahuSign, house and nakshatra of the North Node.
- KetuThe opposite point, with its own sign and house.
- AxisThe pair of houses where the two pull against each other.
How it works
Two points, always opposite.
Shadow planets
Rahu (North Node) and Ketu (South Node) are not bodies. They are calculated points, which is why Jyotish calls them chhaya grahas.
Always 180° apart
Ketu sits exactly opposite Rahu, so the pair forms an axis across two signs and two houses.
18-year cycle
The nodes move backwards through the zodiac and stay about 18 months in each sign. Rahu and Ketu Dashas last 18 and 7 years.
