Retrograde is apparent motion
A centred difference of geocentric longitudes twelve hours before and after the instant supplies degrees per day, correctly unwrapped across 0°. Mercury through Saturn are labelled direct or retrograde; below 0.01°/day is “near station”, an explicit tool threshold rather than an exact station instant. No adverse event is inferred.
Check the recorded clock first
Supports Gregorian dates from 1900–2099. Cities provide historical time-zone rules. Skipped DST clock times are rejected; repeated times require an explicit first or second occurrence. Results retain the UTC instant. Early and future rules depend on the browser database. The example is not your birth record.
Astronomy and symbolism are separate
Positions are calculated locally with Astronomy Engine 2.1.19. Signs use the tropical zodiac: twelve 30° sectors from the equinox, rather than IAU constellation boundaries. The readings are cultural symbolism and reflection, without validated personality, relationship or event prediction.
Keep a piece of sky
The 1200 × 1000 PNG retains selected inputs, rules and a short result; longer readings remain accessible in HTML. Volumetric surface textures are artistic and do not establish real colours, relative sizes or observing conditions. No account is required and inputs are not uploaded.
