Born on September 15
Your Sun is in Virgo, about 22° in — the third decan, where Virgo's core takes on a Mercury flavour. Here's what the date fixes, and what only your birth time can tell you.
Your sign: Virgo
The mutable earth sign that notices everything and refines until it works.
A Virgo Sun has an analytical mind paired with a service orientation — a rare combination. You're the person who actually reads the manual, who notices what's off in the system, who stays late to make sure the thing works the way it's supposed to. You're not loud about it. You just do the work.

Your decan: the third decan of Virgo
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 Virgo belong to Mercury: how you think, learn, communicate, and process information. Read it as Virgo with a Mercury accent — the earth core is unchanged, the emphasis moves.
Ten of Pentacles
Legacy · Wealth · Family. 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 Virgos born on September 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 September 15?
September 15 is Virgo, the mutable earth sign ruled by Mercury. The Sun sits at roughly 22° Virgo on this date, in the third decan.
What decan is September 15?
The third decan of Virgo (20°–30°), sub-ruled by Mercury. Decans divide each sign into three 10° slices; the sub-ruler adds a second flavour to the sign's core — here how you think, learn, communicate, and process information.
What tarot card is September 15?
In the Golden Dawn system each decan has a minor arcana card: for the third decan of Virgo it is the Ten of Pentacles (legacy, wealth, family). It's a birthday card in the same way a sun sign is — one lens, not a verdict.
Does everyone born on September 15 have the same chart?
No. They share the Sun in Virgo, 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 September 15 in different years can have almost nothing else in common in their charts.
