Ayanamsa and chart systems
Our default Vedic birth chart uses the sidereal zodiac with the Lahiri ayanamsa. Ayanamsa is the offset between tropical and sidereal longitudes. Western charts use the tropical zodiac, while KP charts use a separate endpoint that provides sub-lords. Switching systems changes the calculation endpoint; it does not simply toggle the ayanamsa. If a chart response omits houses, the display calculates whole-sign houses from the ascendant. This does not mean that every chart uses the same house system.
The Vedika ephemeris
Vedika provides the planetary calculations used by our astrology tools. Each tool is connected to its configured calculation endpoint. Our integration documentation does not identify the ephemeris library, version, astronomical precision, or supported historical date range. We do not claim that a particular library is used or state a specific accuracy figure. When available, settings returned with a result are more specific than this general description.
What the tools cover
The configured tools cover birth charts, nakshatras, dashas, chart matching, doshas, transits, panchang, and numerology. The Vedic chart shows nine grahas, while the Western chart includes Uranus, Neptune, and Pluto. Some numerology tools calculate digit sums locally and request interpretations from Vedika. The availability of a tool page does not guarantee that its provider will be available for every request.
Inputs and limits
Birth date, time, coordinates, and UTC offset affect a chart. An uncertain birth time makes the ascendant, houses, and timing uncertain; an assumed time is not an exact birth record. Panchang depends on the location, date, and time zone, so check these before using a timing. A sample response is not proof of a personal calculation. Provider outages and missing data can make a tool unavailable.
How PDFs cite their sources
Vedika generates a paid report for the report SKU you purchase. If the engine supplies a PDF, Healers World stores and serves that file unchanged. When an HTML report is converted to PDF, the conversion captures visible headings and text and extracts citation text only from supported visible blocks. It does not create missing citations or independently verify classical chapter-and-verse references. Converted PDFs may not preserve clickable links, so consult the original HTML report when available. Citation formatting varies by report edition, and a Sources appendix is not guaranteed for every PDF. Paid PDFs are currently available only in English, even when the site language is different.
Editorial dates and attribution
Article publication and update dates record when editorial content was added to or changed in our published source collection. These dates come from repository history, not the time when the page is rendered, and do not establish when a deployment went live. A brand byline does not imply professional credentials. We show named reviewers or credentials only when their details have been provided and verified.
