Why Is My Kundli Different on Different Websites?
Compare birth inputs, ayanamsa, house systems and chart layouts before deciding which kundli is wrong. A practical troubleshooting checklist.
You enter the same birthday twice. One website places a planet in the seventh house; another puts it in the sixth. Did a planet move, or did a setting change?
Different chart outputs do not automatically mean different astronomical positions. Start by comparing the inputs and calculation conventions, then compare the interpretation. Two sites can also have a genuine implementation error; matching settings is a diagnostic step, not an excuse for every discrepancy.
First identify what actually differs#
Take a screenshot of both planet tables. A table is easier to compare than two unfamiliar chart drawings.
| Difference you see | First thing to inspect |
|---|---|
| The diagrams look different but planet signs agree | North versus South Indian layout |
| Most planetary degrees differ by a similar amount | Tropical versus sidereal zodiac; ayanamsa |
| Signs agree but house numbers differ | House system or Bhava Chalit view |
| Ascendant differs substantially | Birth time, AM/PM, location and timezone |
| Only Rahu and Ketu differ slightly | Mean versus true node settings |
| D1 is similar but D9 ascendant differs | Precise ascendant degree and birth-time sensitivity |
These are leads, not automatic diagnoses. Keep the exact degrees visible while investigating.
Check the input before judging the software#
Write the date as “5 September 2000” instead of 05/09/2000. Confirm that 12:00 means noon, not midnight. Check the selected town rather than trusting an autocomplete label shared by several places.
The timezone should describe the birthplace at the historical birth date. Your laptop's current timezone is not a substitute. A move abroad does not change the recorded birth instant. Historical daylight-saving rules can matter; do not add or subtract an hour simply because a modern clock shows a different offset.
Next, compare whether seconds were supplied, omitted or rounded. Rounding a time is usually a smaller change than an AM/PM error, but it can matter near a boundary. Our five-minute experiment shows a case where D1 stays in the same ascendant sign while D9 changes.
Compare the calculation contract#
Celestial Digits' standard D1 calculation currently uses a Lahiri sidereal zodiac and whole-sign houses. The ascendant degree is still calculated precisely; a whole-sign first house starting at zero degrees does not mean the ascendant itself is at zero degrees.
If another report uses a different ayanamsa, it is applying a different zodiac reference. If it uses a house-cusp chart, the relationship between houses and signs changes. Swiss Ephemeris documentation distinguishes these computational choices; it does not establish that any astrological interpretation predicts life events.
Do not attempt to resolve these differences by rotating the diagram until it looks familiar. Read North versus South Indian charts for layout differences and Rashi versus Bhava Chalit for calculation differences.
A useful comparison worksheet#
For each report, record the date, time, birthplace, UTC offset, zodiac, ayanamsa, house system and node setting. Then compare the Sun, Moon, ascendant and one slow planet at degree level.
If the settings match and a discrepancy remains, send the provider a minimal example and the exact mismatched values. Remove names and other personal information before sharing publicly. “My Moon is at this longitude under these settings” is much more actionable than “your chart feels wrong.”
Which report should you interpret?#
Choose one documented convention for a reading and apply it consistently. Do not take a favorable yoga from one system and a reassuring house placement from another without explaining the change of method.
Open your Vedic birth chart, compare the tables, and use the JSON export if you need a precise record. The explanation on this page is public; generating a personal reading requires sign-in.
Discussion: Was your discrepancy in a sign, a house or a degree? Describe the setting that resolved it without posting private birth details.
