Date, time and place
These establish the birth moment, location, timezone and house context.
Kundli · Janam Kundli · birth sky
The chart everything else begins from.
A Vedic birth chart, also called a Kundli or Janam Kundli, maps the sidereal positions of the grahas at your date, time and place of birth. Ovati uses this foundation for Moon sign, Nakshatra, Dasha, Sade Sati, compatibility and personal guidance.
Calculated first. Interpreted second.
Ovati separates astronomical calculation from written guidance. Your chart facts are locked before interpretation, helping prevent generated language from inventing planetary positions.
Sidereal framework
Ovati uses Lahiri ayanamsa for its core Vedic calculations.
One chart, many tools
The same profile powers Nakshatra, Dasha, matching and weekly guidance.
From birth details to a Kundli.
A useful chart depends on a traceable sequence. Each step changes a specific part of the result.
Birth moment
Date, local time and timezone establish one exact instant.
Birth place
Latitude and longitude support the Ascendant and local house context.
Sidereal positions
Lahiri ayanamsa converts astronomical longitudes into the sidereal zodiac used here.
Chart context
Grahas, signs, houses and the Moon's Nakshatra become inputs for later tools.
Vedic and Western charts use different reference frames.
Most modern Western astrology uses the tropical zodiac, anchored to the seasonal equinoxes. Jyotish commonly uses a sidereal zodiac intended to remain aligned with the stellar background. The angular difference between those frames is called ayanamsa.
Because ayanamsa choices differ, two sidereal calculators can occasionally place a graha near a sign or Nakshatra boundary differently. Ovati uses Lahiri ayanamsa consistently and carries the same calculated chart into Nakshatra, Dasha, Sade Sati and compatibility.
Why birth time matters
The Moon can move into a different Nakshatra and the Ascendant changes through the day. When the recorded time is uncertain, Ovati should be treated as a reflective screen rather than a definitive house-based reading. See the complete Ovati calculation methodology.
Birth charts, clearly answered.
Is Vedic astrology the same as Western astrology?
No. Vedic astrology generally uses a sidereal zodiac and different interpretive systems, including Nakshatras and Dashas.
What is Lahiri ayanamsa?
It is a widely used reference for converting tropical astronomical longitude into the sidereal positions used in Jyotish.
Can I save charts for my family?
Yes. Ovati supports separate family profiles so each chart and reading keeps the correct birth details.
