Your core self is expressed through usefulness and craft.
Sun sextile your Sun
Twice yearly the Sun comes into sextile with its own birth degree, keeping the angle about two days before moving on, and you get a mild, friendly echo of your birthday without the fuss. Your natal Sun marks the self you keep steering toward — the thing you hope people remember you by, where your pride lives, what makes a day feel properly yours.
Uranus square your Sun
Uranus squares your Sun for nearly two years, usually hitting the exact square three times while it advances, pauses, retreats and advances again. Your Sun is the part that answers to your name, the self you stand behind and the aim you steer by; Uranus is the sudden break and the impatience with whatever has gone stale.
Mercury sextile your Sun
Mercury's sextile to your Sun lasts two days or thereabouts; while it does, your mind is quick and your confidence easy to find. Mercury is the mind putting itself into words; the Sun is the person behind them.
Sun-sign horoscopes read the sky against your Sun. For the most accurate read, also read your rising sign — if you know it, that version is usually the truer story.
