The three phases
First phase: Saturn in the twelfth from the Moon — losses, preparation and closure. Second: Saturn in the Moon sign — peak pressure. Third: Saturn in the second from the Moon — recovery and results.
Each phase lasts roughly two and a half years.
The Katwe method
Shri H.N. Katwe adds eight years before and after the main period because Saturn influences the twelfth and second signs even before entering them.
Our calculator shows both methods with exact phase dates.
How to calculate
You need the natal Moon sign and Saturn transits. Calculations use Swiss Ephemeris with the Lahiri ayanamsha.
