Born on January 21.
The solar coordinate
On January 21 the Sun stands at 0°56′–1°42′ Aquarius. The span, measured at noon UTC across 2024–2027, is why the atlas quotes a range and not a single degree: the calendar drifts against the sky through the leap-year cycle, and your birth year and hour decide where in this band your own Sun sits.
Decan and bound
The degree falls in the 1st decan of Aquarius, whose Chaldean ruler is Venus, and inside the Egyptian bound of Mercury. In traditional practice these sub-rulers shade how the Aquarius Sun expresses itself — a Venus-toned Aquarius rather than a generic one.
