Sade Sati Calculator

The Sade Sati Calculator determines whether you are in Saturn's Sade Sati, the roughly seven-and-a-half year period when the planet Saturn (Shani) transits the three zodiac signs spanning the one before your natal Moon sign, your Moon sign itself, and the one after it. Because Saturn takes about 2.5 years to move through each sign, transiting three consecutive signs centered on the Moon adds up to approximately 7.5 years, which is the literal meaning of 'Sade Sati' (seven and a half).

The tool uses your Moon sign (Rashi), determined from your birth date, time, and place using the sidereal zodiac, then checks Saturn's current sidereal position to identify which of the three phases you are in. The first phase, with Saturn in the twelfth sign from the Moon, is associated with losses and expenses; the second, the 'peak' phase with Saturn over the Moon, with the heaviest pressure on health and mind; and the third, with Saturn in the second sign from the Moon, with financial and family matters easing toward the end. It can also report related Saturn transits like the Dhaiya (Kantaka Shani), the 2.5-year half-period.

People consult Sade Sati to understand challenging stretches involving career setbacks, health, relationships, or hard lessons, and to time major decisions and remedial measures such as mantras, charity, or fasting on Saturdays. It is one of the most widely discussed transits in Vedic astrology precisely because its long duration and association with delay and discipline make it memorable. Despite its reputation, Saturn is also a planet of maturity and reward for honest effort, so the period is read as transformative rather than purely negative.

Enter your accurate birth details so the Moon sign is correct, since Sade Sati is calculated entirely from the natal Moon rather than the Sun sign used in Western astrology. Note the exact phase, because the experience and recommended remedies differ between the rising, peak, and setting stages.
