Free · exact for cusp birthdays

What's my sun sign?

Most charts guess your Sun sign from a fixed date table — but the cusp dates drift about a day from year to year. Starborn computes the Sun's real position for your exact birth date, so a "cusp baby" gets a real answer. Dates shown below are computed for 2026.

✦ Computed with Starborn's own ephemeris — the same public-domain astronomical algorithms the app ships (Schlyter for the Sun & Moon), arc-minute verified against a professional ephemeris. No Swiss Ephemeris.

The math is astronomy; the reading is a mirror; what you do with it is yours.
