October 23: the Sun between 0.0 and 0.8 degrees of Scorpio.
The short answerOctober 23 is usually Scorpio, but not always. Across 1930 to 2035 it falls in Scorpio in 62 years and in Libra in 44, because the moment the Sun changes sign drifts by about six hours a year. The table below gives the exact changeover time for each year, so you can check your own birth year rather than guessing.
Am I Scorpio or Libra?
This is the actual question, and almost every page that comes up for it prints an approximate date range and leaves you no better off. Here is the real answer. The Sun does not change sign at midnight, or on the same date every year. The Earth's year is 365.2422 days rather than 365, so the changeover drifts about six hours later each year and jumps back when a leap day is inserted. Over a century that moves it across two or three calendar dates.
On October 23 specifically, the Sun was in Libra rather than Scorpio in 44 of the 106 years surveyed, mostly in the earlier part of the century.

Born before that time on that date, you are the earlier sign. Born after it, you are the later one. Those times are US Eastern: if you were born elsewhere, convert. Three hours earlier on the west coast, five hours later in London, and so on.
There is no such thing as a cusp signThis is worth being blunt about, because a great deal of writing about October 23 is built on it. You are not half Scorpio and half Libra. The Sun is in one sign or the other at any given moment, and at your moment of birth it was in exactly one of them. The word cusp describes being born near a boundary, which is a real and interesting thing; it does not describe a hybrid sign, which does not exist. What is true is that a Sun at the very end or the very start of a sign behaves a little differently from one in the middle, and that is a statement about degrees rather than about blending.
Where the Sun actually sits on October 23
Not just the sign: the degree. Each sign is thirty degrees wide and the Sun covers roughly one a day, so a birthday pins it to about a degree. On October 23 the Sun falls between 0.0 and 0.8 degrees of Scorpio, the variation coming from the same leap-year drift.

The first decan of Scorpio
Decans are a much older idea than Sun signs and a more specific one. Each sign divides into three ten-degree stretches, each with its own planetary ruler drawn from the Chaldean order, so a Scorpio born in the first decan is not quite the same as one born in the others. October 23 falls in the first, ruled by Mars.
In practice that means the Scorpio traits run through a Mars filter rather than only through Pluto and Mars. The same system assigns a tarot card to every decan: this one is Five of Cups, which is a genuinely useful second description of the same ten degrees and one almost nobody connects back to a birthday.
What a Scorpio born on October 23 is like
The honest version first. A birthday gives you the Sun, and the Sun is one of about ten things in a chart. It describes what you are consciously trying to become rather than how you behave on a Tuesday, which is usually the Moon and the rising sign. Everything born on October 23 in a given year shares this Sun, so nothing on this page is personal to you.
With that said: Scorpio is Water and Fixed, ruled by Pluto and Mars, and the traits most often attached to it are intense, private, loyal, perceptive and all or nothing. Its recognised weak spot is that it tests people before trusting them. The first decan adds Mars, which tends to sharpen that picture rather than soften it.
The three things people most want from astrology, which are their rising sign, their Moon sign and their houses, all need a birth time and a birth place as well as a date. The Moon moves about half a degree an hour, so it can change sign inside a single day. The rising sign changes completely every two hours. A date on its own gets you the Sun and very little else.
This surprises people and it follows directly from everything above. A solar return is the moment the Sun comes back to the exact degree it held when you were born, and a year of that cycle is 365.2422 days rather than 365. So the moment drifts about six hours later each year and snaps back on a leap year, which means it regularly falls on the day before or the day after October 23.
In practice: if you were born late on October 23, your solar return will often land on October 24 in some years. If you were born early in the day, it will sometimes fall on the 22nd. It is not a mistake in the calculation; it is the same quarter-day that moves the sign boundaries.
That matters if you use the technique, because a solar return chart is cast for that exact moment and for wherever you happen to be standing. How to read one is here.
The date opposite October 23
Every point in the zodiac has one directly across from it, and so does every birthday. For October 23 that is April 20, when the Sun sits at roughly the same degree of Taurus, the opposite sign.
The gap between them is 179 days rather than a tidy half of 365, because the Earth moves faster through its orbit in early January, when it is closest to the Sun, than in early July when it is furthest. The two halves of the year are genuinely different lengths, by about seven days.
Astrologically the opposite date is the other end of your axis: Scorpio and Taurus want different things and the tradition treats them as two halves of one problem rather than as enemies. Scorpio and Taurus compatibility is covered here.
Questions people ask
What zodiac sign is October 23?
Usually Scorpio, but Libra in some years. The Sun changes sign at a slightly different moment each year, and on October 23 that lands either side of the boundary depending on the year. The table on this page gives the exact times.
Why do the zodiac dates change from year to year?
Because the Earth takes 365.2422 days to go round the Sun, not 365. The quarter day adds up, so the moment the Sun crosses into a sign drifts about six hours later each year, then jumps back when a leap day is added.
Can I be two signs at once?
No. The Sun is in one sign at any moment, including the moment you were born. Being born near a boundary is real; being half one sign and half another is not.
What decan is October 23?
The first decan of Scorpio, 0 to 10 degrees, ruled by Mars. In the tarot the same ten degrees are the Five of Cups.
