The same answer every time
Results come from fixed rules, not an AI model. The same birth details always give the same result.

Checked accuracy
We check planet positions against NASA JPL Horizons. On 25,571 positions from 1850 to 2149, the Sun and planets agree within 0.001 arc seconds. The Moon agrees within 0.011. An arc second is 1/3,600 of a degree.

Why two tools can give different answers

When another site shows a different sign, house or number, it often uses a different setting. Check these first.

The zodiac offset
Vedic sites do not all use the same ayanamsa (zodiac offset). Ours is Lahiri. Near the edge of a sign, another one can move a planet to the next sign. Western sites use none, so most planets land one sign later.
Time zones and clock changes
A site that ignores daylight saving time can be off by an hour. That moves the rising sign about 15 degrees, so about half the time it changes. Our tools apply the clock rules for the birth date.
Rahu and Ketu
Some sites use the true node (the actual position), others the mean node (an average). Ours is the true node. For John Doe, our sample, the two are 0.78 degrees apart. Near the edge of a sign, that can change the sign.
Houses
Our tools use whole-sign houses: each house is one full sign. Placidus and other house systems can put a planet in a different house.
Letter values
Chaldean letter values, used most in Indian numerology, give John Doe a name number of 7. Pythagorean values, common in Western books, give him 8. Our name tools read the Chaldean one. The life path tool is Western, so it uses Pythagorean.
Master numbers
Some sites keep 11, 22 and 33 (master numbers). Others add the digits again until one is left. John Doe's birth date adds up to 33, so his bhagyank (destiny number) here is 6, marked as a master number. The life path tool keeps master numbers.
