Rashi and the Western sign
Rashi means sign, and the twelve Rashis follow the same order as the Western signs: Mesha is Aries, Vrishabha Taurus, and so on round to Meena, Pisces. What differs is where the circle starts. Western astrology counts from the March equinox, so 0° Aries moves with the seasons. Jyotish counts from the fixed stars, using the Lahiri ayanamsa to place 0° Mesha, and today that point lies about 24° behind the equinox.
The result is a shift that surprises people meeting it for the first time. A Moon at 10° of a Western sign is usually in the preceding sign when measured sidereally, so the Rashi and the Western Moon sign often differ. Neither is a mistake; they answer to different zodiacs.
The sign lords
Each Rashi has a lord, and the lord decides much of how the sign is read. Mesha and Vrishchika belong to Mars, Vrishabha and Tula to Venus, Mithuna and Kanya to Mercury, Dhanu and Meena to Jupiter, and Makara and Kumbha to Saturn. The Sun rules Simha and the Moon rules Karka. Rahu and Ketu, the two lunar nodes, hold no sign in the scheme this site follows.
The Moon has her own set of strengths in Jyotish, and the vocabulary is Vedic: exalted in Vrishabha, in her own sign in Karka, and debilitated in Vrishchika. In every other Rashi she is neither exalted, own nor debilitated. Each Rashi page states which of the three applies, along with the lord’s name and the sign’s Western counterpart.
Rashis and nakshatras
Under the Rashis sits a finer division. The zodiac is cut into 27 nakshatras of 13°20′ each, and a Rashi of 30° holds two and a quarter of them, which is nine padas of 3°20′. The boundaries do not line up, so a nakshatra such as Krittika begins in one Rashi and ends in the next, and its padas are shared between the two.
For that reason the Moon’s Rashi tells you only part of her position. The nakshatra gives the rest, and the lord of the nakshatra opens the Vimshottari dasha sequence. Every Rashi page lists the nakshatras that fall inside it with the name letters of their padas, and the nakshatras hub lists all twenty-seven side by side. To find the Rashi of a particular birth, enter a date, time and city into the Moon sign calculator, and switch it to Vedic to see the Rashi and nakshatra.
The Moon sign in Prashna
Prashna is the Vedic art of answering a question from the chart of the moment it is asked. The asker takes the Lagna, and the Rashi the Moon occupies at that moment, with its lord, shows the state of mind and the way the matter will go. AstroGPT’s Vedic mode reads a Prashna chart for the moment you ask.
