Scorpio Dates: October 23-November 21 - With the Exact Boundary Dates for Your Birth Year
Scorpio is the eighth of the 12 zodiac signs, with dates typically given as October 23-November 21.
Both edges are famously fuzzy, though: the exact answer depends on the birth year and, for a boundary-day birthday, sometimes the hour.
My job here is to pin that answer to a sourced minute rather than a guess.

In 2026, the Sun enters Scorpio on October 23 at 5:38 AM Eastern, or 09:38 UTC, according to the Astro-Seek 2026 calendar. It leaves Scorpio when Sagittarius begins on November 22 at 2:24 AM Eastern, or 07:24 UTC, from the same ingress set.
Those exact times matter only near the boundaries. For most birthdays inside the window, the familiar date range works without drama.
Was I a Scorpio in My Birth Year?
Enter your birth month, day and year below. Time is optional, but a boundary-day birthday without one receives an honest incomplete verdict rather than a made-up answer.
A verdict names Scorpio or the neighboring sign, with that year's ingress date, time, zone and source. On a switch day without a birth time the hour stays open - this page will not guess.

Scorpio Boundary Dates by Year: October 22 or 23, November 21 or 22
Scorpio has a double-fuzzy boundary. Its start can fall on October 22 or 23, while its end can fall on November 21 or 22. One widely cited static convention even begins Scorpio on October 24.
I checked four kinds of references and got October 22, October 23, October 24 and November 22 among the answers. That sounds chaotic until each date is attached to a year, place and exact ingress time.
In 2026, the Sun enters Scorpio on October 23 at 5:38 AM Eastern. An October 23 birth that year is Libra before 5:38 AM and Scorpio after it. Source: Astro-Seek's 2026 astrology calendar, with 09:38 UTC converted to Eastern time.
In 2026, the Sun leaves Scorpio on November 22 at 2:24 AM Eastern. A November 22 birth is Scorpio before that moment and Sagittarius afterward. Source: Astro-Seek's 2026 ingress set, where the switch occurs at 07:24 UTC.
The pattern changes in nearby years. In 2025, Scorpio starts on October 22 at 11:51 PM Eastern, so October 23 is Scorpio all day. Cafe Astrology supplies the Eastern-time cusp table, and the October 23, 03:51 UTC value matches the Royal Observatory of Belgium's 2025 table.
In 2024, Scorpio begins on October 22 at 6:14 PM Eastern. Sagittarius arrives on November 21 at 2:56 PM Eastern, making November 22 Sagittarius all day. Source: Cafe Astrology's Eastern-time cusp tables.

Boundary-Day Decision Card
- Find the switch moments. Locate your birth year in the table and note both the Scorpio start and end.
- Compare the time. If your birthday is on that year's exact switch date, compare your birth time with the listed moment. A birth certificate is the usual place to look.
- Leave the hour open when necessary. Without a birth time, the checker cannot settle a switch-day birth. That does not make anyone two signs; it means one piece of data is missing.

Who prints which Scorpio window?
| Source | Scorpio window it prints | Note |
|---|---|---|
| Mainstream portals | Oct 23-Nov 21 | Common static convention |
| Old Farmer's Almanac | Oct 23-Nov 22 | End differs by one day |

| AstroLibrary | Oct 22-Nov 23 | Worldwide span across time zones |
| This page | Year-indexed exact times | Uses the local switch moment |
These published conventions were compared on August 14, 2026. AstroLibrary's October 22-November 23 span covers possible dates across all world time zones in its 2026-2028 city tables. It is wider than any single US local window and should not be read as one.
Why Scorpio Dates Shift a Little Every Year
A tropical year lasts about 365.2422 days, so an ingress tends to drift roughly six hours later from one year to the next. A leap day shifts the pattern back by about 18 hours, which is why Scorpio's start bounces between October 22 and 23 and its end between November 21 and 22.
That is the useful version. The fuller mechanism belongs with the 12 zodiac signs, not in a boundary lookup. Source: timeanddate.com's tropical-year and equinox reference.
Scorpio's Attributes: Water, Fixed, and the Two Rulers
Scorpio belongs to the Water element alongside Cancer and Pisces. Its modality is Fixed, grouped with Taurus, Leo and Aquarius; in the traditional scheme, Fixed signs sustain the middle portion of a season. Scorpio also carries negative polarity.
The two-ruler answer requires keeping two traditions visible. Classical astrology worked with seven visible planets and assigned two signs to each planet in its rulership scheme. Mars ruled Aries and Scorpio.
After Pluto's discovery in 1930, modern astrology added it as Scorpio's co-ruler. References still differ on whether Mars or Pluto should lead, so I show both instead of smoothing away a real disagreement. Cafe Astrology's rulership reference and the astrological-sign master table record these classical and modern assignments.
Scorpio's symbol is the Scorpion, represented by the glyph ♏, or U+264F. I treat the recorded symbol as enough; adding an unsupported myth would not make the date calculation better.
On the ecliptic, Scorpio occupies 210-240 degrees. It is the eighth of 12 signs, each covering 30 degrees, and its opposite sign is Taurus. The Taurus dates page handles that sign's own window, while zodiac basics explains elements, modalities, polarities and oppositions.
Scorpio Traits as the Tradition Tells It
Classic Western astrology literature traditionally describes Scorpio as intense, private, determined and transformative. Its traditional shadow vocabulary includes jealousy. These are inherited symbolic descriptions, not findings about everyone born within a particular 30-degree slice of the zodiac.
Traditional symbolic descriptions are for entertainment and self-reflection, not science. A Sun sign is one part of a much larger chart, and it is not a tool for judging people.
I don't read daily horoscopes - I like the zodiac as a mirror, not a map. For me, trait language can offer a prompt such as "Where am I being private?" without turning that prompt into an identity test (or a claim about somebody else). What astrology can and can't tell you sets out that boundary in more detail.
Scorpio Compatibility: the Traditional Associations
The most common convention pairs Water with Water and Earth. For Scorpio, Cancer and Pisces are frequently listed, as are the Earth signs Taurus, Virgo and Capricorn.
These are traditional symbolic associations for entertainment and self-reflection, not scientific relationship predictions. Lists vary by source, a Sun sign alone does not decide synastry, and no pairing is a verdict on a real relationship.

Scorpio Season Across October and November
Scorpio crosses parts of two calendar months. Its October boundary falls on the 22nd or 23rd depending on the year, while its November boundary falls on the 21st or 22nd. The exact local switch time, rather than the month label, settles a boundary birthday.
Scorpio FAQ: Boundary Days, Two Rulers, and the Six-Day Rumor
Is October 23 Scorpio or Libra?
It depends on the year and, if October 23 is the switch day, the hour. In 2026 Scorpio starts October 23 at 5:38 AM Eastern, but the 2024 and 2025 starts occurred on October 22, making October 23 fully Scorpio in those years.
Is November 22 Scorpio or Sagittarius?
The birth year decides. In 2026 the switch occurs November 22 at 2:24 AM Eastern, with Scorpio before and Sagittarius after; in 2024, 2025 and 2029 Sagittarius arrives on November 21, making November 22 Sagittarius all day.
Why does Scorpio have two ruling planets?
Mars is Scorpio's classical ruler under the seven-visible-planet scheme. Pluto, discovered in 1930, became its modern co-ruler, and traditions differ on which one leads. I list both because the disagreement is real.
Is Scorpio really only six days long?
No, that claim mixes a constellation with a tropical sign. The Sun crosses the Scorpius constellation for about a week, roughly November 23-30, while tropical Scorpio spans 30 degrees and lasts about 30 days. Ophiuchus is another constellation the ecliptic crosses, not a 13th sign of the tropical zodiac.
How do I settle my sign for sure if I was born on a boundary day?
Compare your birth year and time, usually found on a birth certificate, with the exact switch moment. If the time is unavailable and your date is the switch date, the honest answer is that the hour stays open. You are not a hybrid of two Sun signs.
Does the checker store my birthday?
No. Everything is processed in your browser, and the birth data is never stored or sent anywhere. The calculation uses the same year-indexed boundary table displayed on this page.
Drop your birthday and birth year into the checker above - and if you were born on October 22 or 23, or November 21 or 22, dig out your birth time first. That minute is what settles it.
