Beyond a birthday lookup table
The Sun’s apparent geocentric ecliptic longitude determines its 30° sign. Within 1° of a boundary, the tool suggests checking the time; this is a reminder threshold. Unknown times use a labelled noon sample, or the first available civil clock if noon was skipped, with the available day’s endpoint longitudes, and no single certain sign if a boundary is crossed. Elements and modalities frame self-expression.
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.
