Transparency and Reliability in Sky Calculations
Every chart you open in Mirror is calculated from real sky data for that day and coordinates. It's based on astronomical measurements, not guesses.
While developing the engine, we compared it with NASA JPL Horizons, Minor Planet Center, and common ephemerides after every update. We continue the same tests today so you only see verified values on your screen.
NASA JPL Horizons
We compare every chart with NASA Horizons data; so the degrees you see on your screen match the real sky exactly.
When a new version is released, we recalculate the same date-times and don't proceed without fixing any deviations.
Minor Planet Center
We check asteroids and special points with the MPC catalog to maintain the same accuracy for small bodies.
These checks are only for reliability; each coordinate is matched with the MPC list without sharing user data.
Global Astrological References
We compare results with classical ephemerides like Swiss Ephemeris and VSOP87 to show our method stays consistent with industry standards.
The goal isn't to sell data; it's only to prove that the engine working for you is compatible with globally accepted tables.

Open your own chart with the same verified engine
The same calculation chain you see in examples is available to everyone. By entering your date-time and location, you can see personal results in seconds.
Create your own chartHow Do We Verify?
We Compare with Reliable Astronomical Sources
We put every calculated degree side by side with NASA Horizons and MPC data; if we see a difference, we find the cause and don't show it to you without fixing it.
We Work Compatible with Globally Used Ephemerides
Tests we do with tools like Swiss Ephemeris and VSOP87 prove that the degrees and houses you see in Mirror match international tables.
We Provide a Transparent Process
If you wonder how we test, we share example tables, screenshots, and links; you can enter the same date-time-location and see the same result yourself.
Where Are the Example Verification Reports?
We explain the process here; the numbers, screenshots, and Horizons links are waiting for you on the Verifications > Example Cards page.
So you can first read the story here, then open the real tables with one click and verify each line yourself.
See Example VerificationsWhy Is This Important?
Interpretations are only meaningful when the underlying data is accurate. That's why we first make the planetary positions accurate, then write the story.
The reason you see the same result when you enter the same date, time, and location again is this precision.
Mirror's Difference
AI only organizes the text; the chart itself is prepared with real sky data and tested models.
We summarize the method here, share examples in the technical report, and ensure everyone sees the same result.
Just a few steps
If you've read the verification process, the next step is simple: The same reliable calculation prepares your chart in a few minutes. Go to the analysis screen, enter your date-time information, and see your personal interpretation.
