October 23 zodiac sign
October 23 is the main changeover date: in most years the Sun leaves the anaretic 29° of Libra and enters Scorpio during the day, so this birthday belongs to one sign or the other.

October 23 in profile
There is no cusp sign in astrology; an October 23 birthday is Libra or Scorpio depending on year and exact time, and the table on this page shows which. On the Libra side, the Sun sits at 29°, the anaretic degree, where the sign’s lessons about balance and partnership are urgent and concentrated. On the Scorpio side, it is at 0°, the first degree of fixed water, raw and intense, with Mars as ruler of sign and decan (Pluto in modern astrology).
Money is a matter of trust and control. Late Libras like fair deals and shared accounts that are scrupulously balanced. Early Scorpios guard their finances closely and dislike debt. Both are careful with joint purchases and want transparency. They may keep a private savings pot or a clear rule about lending to friends, and both sides are wary of mixing love and money.
Ambition works quietly on both sides of the line. They aim for influence: a seat at the table, a voice in decisions. The Libra side builds alliances, the Scorpio side works behind the scenes. Each will spend years earning a position of trust before using it. The useful habit is defining success in personal terms, so that the drive for control does not crowd out the pleasure of shared achievement.
Libra or Scorpio?
The Sun moves from Libra into Scorpio around October 23, and the exact moment shifts from year to year. Between 1930 and 2040 it happened during the UTC day of October 23 in 86 years out of 111, at a median of 13:27 UTC (12:12 UTC in births from 1980 to 2010). In 18 years the whole day was still Libra. In 7 years it was already Scorpio all day. So an October 23 birthday is Libra or Scorpio depending on the year and the time, never a blend of the two.

Compatible signs for a Libra
Sun-sign compatibility starts from the element. Libra gets on most easily with its own element and with the two sextile signs, and feels the strongest pull from its opposite. For an October 23 birthday, in the Gemini decan, Gemini is a natural match. The full charts decide how a real pairing feels.
