Born on January 15
Your Sun is in Capricorn, about 25° in — the third decan, where Capricorn's core takes on a Sun flavour. Here's what the date fixes, and what only your birth time can tell you.
Your sign: Capricorn
The cardinal earth sign that plays the long game and refuses to be flashy about it.
A Capricorn Sun is built around discipline and long-term thinking. You're the friend who actually executed on the plan everyone else was just talking about. You don't need praise for doing what you said you'd do — that's just baseline integrity to you. People often underestimate Capricorns at twenty-five and overestimate everyone else; by forty, the curve catches up, and the people who took you for slow find out you were just consistent.

Your decan: the third decan of Capricorn
Each sign is divided into three 10° decans, and each decan has a sub-ruler that shades the sign's core. Degrees 20–30 of Capricorn belong to Sun: the core of who you are — your conscious identity, your will, your essential self. Read it as Capricorn with a Sun accent — the earth core is unchanged, the emphasis moves.
Four of Pentacles
Security · Control · Holding on. The card assigned to this ten-degree slice of the zodiac — a birthday card in the same sense a sun sign is a birthday sign: one lens on the date, not a verdict.

The Sun is one placement out of ten. Your Moon sign changes every two to three days, so Capricorns born on January 15 in different years have different Moons; your rising sign changes every two hours and needs a birth time and place. Those two carry most of what people mean by "personality" in a chart.

Common questions
What zodiac sign is January 15?
January 15 is Capricorn, the cardinal earth sign ruled by Saturn. The Sun sits at roughly 25° Capricorn on this date, in the third decan.
What decan is January 15?
The third decan of Capricorn (20°–30°), sub-ruled by Sun. Decans divide each sign into three 10° slices; the sub-ruler adds a second flavour to the sign's core — here the core of who you are — your conscious identity, your will, your essential self.
What tarot card is January 15?
In the Golden Dawn system each decan has a minor arcana card: for the third decan of Capricorn it is the Four of Pentacles (security, control, holding on). It's a birthday card in the same way a sun sign is — one lens, not a verdict.
Does everyone born on January 15 have the same chart?
No. They share the Sun in Capricorn, but the Moon changes sign every two to three days, the rising sign every two hours, and the outer planets by year. Two people born January 15 in different years can have almost nothing else in common in their charts.
