October 4 zodiac sign: Libra, second decan
If you were born on October 4, your sign is Libra, the air sign ruled by Venus: the Sun is in Libra on this date in every year from 1980 to 2030. The Sun sits about 11° into Libra on this date, in the second decan, where Libra's core takes on a Saturn flavour. Here's what the date fixes, and what only your birth time can tell you.
Your sign: Libra
The cardinal air sign that lives in relationship and refuses to choose between two goods.
A Libra Sun is built around fairness and the relational fabric. You're allergic to bullies and to anyone who treats other people as means rather than ends. You see all sides — the gift and the curse of your sign — and you're often the person who can name what each side actually wants when everyone else has lost the thread.

The date fixes the Sun; the hour fixes the rest. A Libra born October 4 in the late morning has Sagittarius rising, and a different first impression from one born at dawn. Your rising sign needs the birth time; the twelve Libra Sun combinations show what each one changes.

In 22 of those 51 years (43%) the Moon changed sign during October 4 itself, so in those years the birth time decides the Moon as well as the rising sign. Cells with an arrow mark them, with the UTC time of the change. The Moon was exactly full on October 4 in 1990 and 2009; it was never new on this date between 1980 and 2030.
Find your birth year. One sign means the Moon spent the whole UTC day there; an arrow means it changed sign that day, at the UTC time shown: born before it, the first sign; after it, the second. The Moon sign calculator settles it in seconds; your birth chart adds the rising sign and houses.
Times in UTC: a birth late in the evening in the Americas, or early in the morning in Asia, can fall on the neighbouring UTC date.

Your decan: the second decan of Libra
Each sign is divided into three 10° decans, and each decan has a sub-ruler that shades the sign's core. Degrees 10–20 of Libra belong to Saturn: where you face limitation and, through facing it, build mastery. Read it as Libra with a Saturn accent — the air core is unchanged, the emphasis moves.

What the date can't tell you
The Sun is one placement out of ten. Your Moon sign changes every two to three days, so Libras born on October 4 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 October 4?
October 4 is Libra, the cardinal air sign ruled by Venus. The Sun sits at roughly 11° Libra on this date, in the second decan.
What decan is October 4?
The second decan of Libra (10°–20°), sub-ruled by Saturn. Decans divide each sign into three 10° slices; the sub-ruler adds a second flavour to the sign's core — here where you face limitation and, through facing it, build mastery.
What tarot card is October 4?
In the Golden Dawn system each decan has a minor arcana card: for the second decan of Libra it is the Three of Swords (heartbreak, grief, painful truth). It's a birthday card in the same way a sun sign is — one lens, not a verdict.
What Moon sign is someone born on October 4?
It depends on the year, and in 43% of years on the hour too. For example: in 1980, Leo; in 1990, Aries; in 2000, Sagittarius or Capricorn; in 2010, Leo or Virgo; in 2020, Taurus. Over 1980–2030 the Moon on October 4 was most often in Leo. A birth time and place pin it down.
Does everyone born on October 4 have the same chart?
No. They share the Sun in Libra, 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 October 4 in different years can have almost nothing else in common in their charts.
