Why the two zodiacs give different signs
Tropical astrology begins Aries at the March equinox and keeps the zodiac aligned with the seasons. Sidereal astrology accounts for the gradual shift between that seasonal point and the fixed stars.
The two zodiacs now differ by more than twenty degrees, so a planet can appear in different signs in the two systems. The planet has not moved. The systems are using different reference points.
Two maps, one birth
A tropical chart may place the Sun in Taurus while a sidereal chart places it in Aries. Western astrology interprets the tropical placement within its own system.
Jyotish interprets the sidereal placement together with the lagna, Moon, houses, nakshatras, and dasha. One result does not need to be inserted into the other system. They can both describe the same birth without becoming one chart.
Moon, lagna, and timing
Western sun-sign talk often stops at the month of birth. Jyotish asks for the minute.
The lagna starts the houses. The Moon and its nakshatra describe mind and path, and usually begin the dasha clock. Without an honest birth time, the map is the wrong sky. That demand is sharper than a tropical Sun column, which stays put for about a month.
How this site uses the sidereal chart
VedicAstrology.com does not combine tropical and sidereal placements in one interpretation. It calculates the sidereal janam kundli and reads the lagna, Moon, grahas, houses, nakshatras, and dasha within Jyotish.
Bring your date, exact time, and place of birth, then ask about the part of life you want the sidereal chart to explain.
