Born on March 23
Your Sun is in Aries, about 2° in — the first decan, where Aries's core takes on a Mars flavour. Here's what the date fixes, and what only your birth time can tell you.
Your sign: Aries
The first sign of the zodiac — initiator, fighter, and patron of fresh starts.
If your Sun is in Aries, your core identity is built around action. You feel most yourself when you're starting something — a project, a fight, a workout, a brand-new chapter. You hate stagnation more than you hate failure. The slow consensus-building meetings and the relationships that need careful tending? That's not where you shine. You shine in the opening move, the new venture, the moment someone needs to just decide already.

Your decan: the first decan of Aries
Each sign is divided into three 10° decans, and each decan has a sub-ruler that shades the sign's core. Degrees 0–10 of Aries belong to Mars: your drive — how you take action, what makes you angry, and what you fight for. Read it as Aries with a Mars accent — the fire core is unchanged, the emphasis moves.
Two of Wands
Planning · Decisions · Discovery. 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 Aries born on March 23 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 March 23?
March 23 is Aries, the cardinal fire sign ruled by Mars. The Sun sits at roughly 2° Aries on this date, in the first decan.
What decan is March 23?
The first decan of Aries (0°–10°), sub-ruled by Mars. Decans divide each sign into three 10° slices; the sub-ruler adds a second flavour to the sign's core — here your drive — how you take action, what makes you angry, and what you fight for.
What tarot card is March 23?
In the Golden Dawn system each decan has a minor arcana card: for the first decan of Aries it is the Two of Wands (planning, decisions, discovery). It's a birthday card in the same way a sun sign is — one lens, not a verdict.
Does everyone born on March 23 have the same chart?
No. They share the Sun in Aries, 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 March 23 in different years can have almost nothing else in common in their charts.
