Birth chart

Your calculated chart. Method and limits included.

Explore your sidereal chart placements and learn why they can differ from Western tropical labels. The calculation requires an exact birth time and uses Zohvia's named PAC fixed-initial-point model.

Birth details

Arjun's chart

NameDate of birthAdults 18 or older only. Birth instants must resolve on or after 1 January 1972.

Time of birthBirth time unknown

Enter the recorded seconds; do not estimate or round the birth time.Birth placeType a city, then choose its full city, region, and country suggestion.

Confirm exact birth-site coordinates and timezone

The selected city center is a timezone aid only and is not used for the chart. Search for the birth site below to fill its coordinates, or enter them from a birth record, then verify the IANA timezone shown for that exact site and confirm both. Zohvia validates their formats but cannot independently verify the site or zone.

Find the birth site (optional external lookup)

Choosing “Search with OpenRouteService” sends this search text through Zohvia to OpenRouteService. Include only a place. Other birth fields and your browser’s IP address are not forwarded to the provider. Typing and bundled city selection send no request. You can enter coordinates yourself using the bundled city/timezone selector. Privacy policy

Why this happens

Different zero points, about 24 degrees apart.

Tropical astrology fixes its zero point to the equinox. Sidereal systems subtract an ayanamsha from tropical longitude. Zohvia uses a named geometric interpretation of PAC's fixed initial point; this is not PAC approval, and other software, ayanamshas, and practitioners can produce different boundary results.

Good to know

Birth chart questions

Why is my Vedic sign different from the sign I already know?

Tropical astrology anchors 0° Aries to the equinox. Sidereal systems apply an ayanamsha offset to use a different zero point. Zohvia applies its named PAC fixed-initial-point model, currently about 24°; this is not PAC approval, and neither zodiac is the same thing as modern constellation boundaries.

Is one system 'more correct' than the other?

They are different coordinate conventions used by different traditions. Zohvia selects a sidereal convention for its traditional chart rules. That choice does not make astrological interpretation scientifically validated or more objectively true.

What is a nakshatra, and why 27 instead of 12?

In Zohvia's calculation, a nakshatra is one of 27 equal segments of sidereal Moon longitude, with four padas per segment. Traditions attach meanings and naming customs to those segments; those meanings are symbolic rather than scientifically validated traits.

How precise is this chart?

The chart shows named placements, rather than exact longitude values. An exact recorded time and confirmed place are required; Zohvia withholds results when a numerical boundary makes a label uncertain. Its PAC fixed-initial-point sidereal model can differ from another system near a boundary. The methodology explains the reference checks and remaining limits; this is not PAC approval or practitioner certification.
