How this sidereal birth chart calculator works
The calculator converts your local birth time to UTC using your birthplace, calculates planetary positions, and applies the Lahiri ayanamsha for the Vedic zodiac. The AI explains those calculated placements; it does not invent the planetary positions.

Born in the United States?
Enter the clock time recorded at birth and select the actual city where you were born. Do not convert the time to India time or to your current time zone. The calculator uses the selected location and birth date for time-zone conversion. Check the selected city carefully, especially when several cities share a name.
Some clock times repeat when daylight saving ends, and others do not exist when it begins. If your record falls in that transition hour, confirm its UTC offset before relying on a precise ascendant. Historical time-zone records can also be uncertain.
Why might your sign change?
Most Western Sun-sign horoscopes use the tropical zodiac. A Vedic chart uses a sidereal zodiac. The difference depends on the date and ayanamsha; it is not a rule to subtract exactly one sign. Compare the two systems.
