Zodiac Signs Dates: Your Complete Calendar From Aries to Pisces

Most people know their zodiac sign almost as automatically as they know their birthday. A March birthday might mean Pisces or Aries, while someone born in late October may identify as Libra or Scorpio. The dividing line looks straightforward until two different zodiac calendars give slightly different answers.

Zodiac signs dates are the conventional birthday ranges assigned to the twelve Sun signs in Western tropical astrology. Each sign occupies 30 degrees of the zodiac, and the Sun moves from one section to the next at a specific moment. Because that moment can fall on different civil dates from year to year, familiar zodiac date charts are approximations rather than exact rules for every birth.

This distinction matters most for people born near the beginning or end of a sign. Someone born on May 10 can identify Taurus without much uncertainty, but a birthday on May 20 or 21 may require checking the birth year and time.

The following guide provides the complete zodiac signs and dates chart, explains the symbols, elements and ruling planets, and shows how to confirm your Sun sign when a birthday falls close to a boundary.

Zodiac Signs Dates Chart: All 12 Sun Signs

The standard zodiac signs dates chart lists twelve approximate periods, beginning with Aries in March and ending with Pisces in February and March. These are the familiar ranges commonly used in Western tropical astrology.

These zodiac signs dates are approximate. For example, in 2026 the Sun entered Aries on March 20 and Leo on July 22 in UTC, even though many familiar charts print March 21 and July 23 as their starting dates.

A conventional chart works for most birthdays because only a small group of people are born close enough to a transition for the difference to matter.

If your birthday is within approximately a day of a sign boundary, use the exact solar ingress for your birth year rather than relying on a generic table.

What Do Zodiac Signs Dates Actually Represent?

Zodiac signs dates represent the periods when the Sun occupies each of the twelve equal sectors of the Western tropical zodiac. They are not the dates when the Sun passes through the corresponding astronomical constellations as defined by modern astronomy.

The tropical zodiac begins at the March equinox. This point is defined as 0° Aries, and every subsequent sign covers another 30 degrees of ecliptic longitude.

The full sequence is:

1. Aries – 0° to 30°
2. Taurus – 30° to 60°
3. Gemini – 60° to 90°
4. Cancer – 90° to 120°
5. Leo – 120° to 150°
6. Virgo – 150° to 180°
7. Libra – 180° to 210°
8. Scorpio – 210° to 240°
9. Sagittarius – 240° to 270°
10. Capricorn – 270° to 300°
11. Aquarius – 300° to 330°
12. Pisces – 330° to 360°

The Sun appears to move along this circular system as Earth travels around it. When the Sun crosses a 30-degree boundary, it enters the next tropical sign.

This explains why the actual moment matters for cusp birthdays. The zodiac does not switch signs because a calendar reaches midnight. It switches when the Sun reaches the required longitude.

The Twelve Zodiac Signs: Dates, Meanings and Ruling Planets

Each zodiac sign combines a conventional date range, an element, a modality and a traditional planetary ruler. Together, these categories form the basis of familiar Sun-sign descriptions.

They belong to astrology's symbolic framework rather than scientifically demonstrated personality classifications.

Aries Dates and Meaning: March 21 – April 19

Aries zodiac signs dates traditionally begin around March 21 and continue through April 19, although the Sun frequently enters Aries on March 20. Aries is the first sign of the tropical zodiac and begins at the March equinox.

Aries belongs to the fire element and cardinal modality. Its traditional planetary ruler is Mars, and the Ram symbolizes initiative, determination and direct action.

The Aries archetype is often associated with starting projects, speaking openly and approaching challenges with confidence. Its symbolic difficulties involve impatience and acting before considering all consequences.

A person born March 25 is conventionally Aries. Someone born March 20 should check the exact entry time for their year and location.

Taurus Dates and Meaning: April 20 – May 20

Taurus zodiac signs dates usually extend from April 20 to May 20, though the transition into Gemini may occur on May 21. Taurus is a fixed earth sign traditionally ruled by Venus.

The Bull symbolizes persistence, comfort, stability and the enjoyment of tangible experiences. Traditional interpretations emphasize patience, reliability and the desire to create lasting results.

The potential challenge associated with Taurus symbolism is resistance to change. Consistency may become inflexibility when circumstances require a different approach.

Most people born in early May are safely within Taurus season. April 19–20 and May 20–21 are the dates most likely to need confirmation.

Gemini Dates and Meaning: May 21 – June 20

Gemini zodiac signs dates are conventionally May 21 through June 20, although the Sun's transition into Cancer can occur on June 21. Gemini is a mutable air sign traditionally ruled by Mercury.

The Twins symbolize duality, curiosity, communication and the capacity to consider different perspectives. The Gemini archetype is often associated with flexible thinking and an interest in discovering new information.

Its traditional difficulty involves becoming distracted or continually changing direction. Curiosity can create opportunities, but it may also make sustained focus harder.

A birthday on June 10 is conventionally Gemini. A birthday near May 21 or June 21 requires more attention to exact solar positions.

Cancer Dates and Meaning: June 21 – July 22

Cancer zodiac signs dates generally begin around June 21 and continue through July 22. Cancer starts at the June solstice in the tropical zodiac and is classified as a cardinal water sign.

Its traditional ruler is the Moon, while the Crab symbolizes protection, familiarity and emotional sensitivity. Common astrological themes include nurturing, home life and the wish to feel secure.

The traditional challenge involves balancing sensitivity with clear boundaries. Seeking reassurance can be supportive, but it becomes less useful when needs remain unspoken.

Someone born July 10 is usually Cancer. July 22 or 23 can be a boundary case because Leo season begins at a year-specific moment.

Leo Dates and Meaning: July 23 – August 22

Leo zodiac signs dates are conventionally July 23 to August 22, although Leo can begin on July 22 in some years. Leo is a fixed fire sign ruled by the Sun.

The Lion symbolizes confidence, creativity, warmth and visible self-expression. Traditional Leo descriptions emphasize generosity, loyalty and a desire to be recognized for meaningful contributions.

Its symbolic difficulty is balancing appreciation with humility. A wish for recognition becomes more constructive when equal attention is given to others.

An August 5 birthday is conventionally Leo. Someone born July 22 or August 22–23 should verify the exact solar transition.

Virgo Dates and Meaning: August 23 – September 22

Virgo zodiac signs dates usually run from August 23 through September 22, with possible year-specific differences near Libra's beginning. Virgo is a mutable earth sign traditionally ruled by Mercury.

The Maiden represents discernment, observation and the careful organization of practical matters. Traditional descriptions emphasize attention to detail, useful problem-solving and thoughtful support.

Virgo's symbolic difficulty is allowing perfectionism to become criticism. Practical thinking can be valuable without requiring every situation to be optimized.

Most early-September birthdays are clearly Virgo. September 22 or 23 can require a more precise calculation.

Libra Dates and Meaning: September 23 – October 22

Libra zodiac signs dates generally extend from September 23 to October 22, although Libra can begin on September 22 in certain local time zones and years. Libra starts at the September equinox in the tropical zodiac.

Libra is a cardinal air sign traditionally ruled by Venus. The Scales symbolize fairness, cooperation, relationships and the effort to consider different perspectives.

Traditional Libra descriptions emphasize diplomacy and appreciation for harmonious environments. The potential challenge is postponing decisions or avoiding a disagreement that requires attention.

An October 10 birthday is clearly Libra under the conventional system. Birthdays on September 22–23 and October 22–23 need closer checking.

Scorpio Dates and Meaning: October 23 – November 21

Scorpio zodiac signs dates are usually October 23 through November 21, although Sagittarius may begin on November 22. Scorpio is a fixed water sign traditionally ruled by Mars, with Pluto commonly used as a modern ruler.

The Scorpion symbolizes determination, privacy and emotional depth. Traditional interpretations often emphasize trust, resilience and a desire to understand what lies beneath appearances.

The symbolic difficulty involves distinguishing trust from control. Emotional closeness is most constructive when personal boundaries remain respected.

A November 5 birthday is conventionally Scorpio. Someone born October 23 or November 21–22 should verify the transition.

Sagittarius Dates and Meaning: November 22 – December 21

Sagittarius zodiac signs dates generally begin around November 22 and continue through December 21, although Capricorn can begin on December 21 or 22. Sagittarius is a mutable fire sign traditionally ruled by Jupiter.

The Archer symbolizes exploration, direction and the desire to discover broader perspectives. Traditional descriptions emphasize curiosity, optimism and personal freedom.

Its symbolic difficulty is balancing spontaneous enthusiasm with dependable commitments. Exploration and responsibility can coexist when expectations are clear.

A December 10 birthday is conventionally Sagittarius. December 21 is a frequent boundary date that should not be resolved by a generic chart alone.

Capricorn Dates and Meaning: December 22 – January 19

Capricorn zodiac signs dates are conventionally December 22 through January 19, but Capricorn can begin on December 21. The sign starts at the December solstice and belongs to the cardinal earth category.

Capricorn's traditional ruler is Saturn. The Sea-Goat symbolizes ambition, persistence, responsibility and the effort to establish lasting structures.

The archetype emphasizes planning and practical achievement. Its symbolic challenge involves balancing responsibilities with emotional expression and time for rest.

January 10 is conventionally Capricorn. December 21–22 and January 19–20 deserve careful checking.

Aquarius Dates and Meaning: January 20 – February 18

Aquarius zodiac signs dates generally run from January 20 through February 18, with the exact entry into Pisces occasionally falling on February 18. Aquarius is a fixed air sign, despite its water-bearing symbol.

The traditional ruler is Saturn, while Uranus is commonly used as its modern ruler. The Water Bearer symbolizes individuality, intellectual curiosity and broader social concerns.

Traditional descriptions emphasize independent thinking and appreciation of unusual perspectives. The challenge involves balancing personal freedom with emotional availability.

An early-February birthday is conventionally Aquarius. January 19–20 or February 18–19 may need a year-specific calculation.

Pisces Dates and Meaning: February 19 – March 20

Pisces zodiac signs dates are conventionally February 19 to March 20, although Pisces can begin on February 18 and Aries on March 20. Pisces is a mutable water sign traditionally ruled by Jupiter, with Neptune commonly used as a modern ruler.

The Fishes symbolize imagination, sensitivity and reflection. Traditional interpretations emphasize compassion, creativity and emotional understanding.

Its symbolic difficulty is maintaining clear boundaries when empathy or imagination becomes overwhelming.

February 29 is normally a Pisces birthday in the tropical zodiac. Birthdays around February 18–19 or March 20–21 deserve exact confirmation.

Why Zodiac Signs Dates Change Between Years

Zodiac signs dates can shift by approximately a calendar day because solar transitions occur at precise astronomical moments rather than at fixed midnight boundaries. The Gregorian calendar's leap-year system and local time-zone differences influence which civil date contains the event.

Earth's orbital period does not consist of an exact whole number of calendar days. Leap days help maintain the calendar's relationship with the seasons, but they do not make every solar ingress occur at the same local date and time.

The tropical zodiac also follows solar longitude, not the printed birthday ranges in popular horoscope tables.

For example, the Royal Observatory of Belgium lists Aries beginning on March 20 in both 2026 and 2027, even though a common zodiac chart uses March 21 as the first Aries date.

This is not an error in astronomy. The traditional table is simply a simplified calendar reference.

Zodiac Signs Dates in 2026 and 2027

The year-specific zodiac signs dates for 2026 and 2027 demonstrate how actual solar transitions differ from conventional birthday ranges. The following table shows the dates of each new tropical Sun-sign period, expressed as dates in UTC.

These dates are based on published solar ingress tables. Some local time zones can show the preceding or following date, and people born on the transition date need the precise hour and minute.

The year-specific table should not be applied to people born in unrelated years. A person born in 1994, for example, needs the solar positions for 1994.

What Does Being Born on a Zodiac Cusp Mean?

A zodiac cusp birthday is a birthday close to the moment when the Sun moves from one tropical sign to the next. It does not mean that the Sun occupies two zodiac signs simultaneously.

Popular astrology sometimes describes people as Aries–Taurus cusps or Cancer–Leo cusps. Those labels are informal descriptions of dates near sign boundaries rather than separate zodiac placements.

At a specific instant, the Sun has one zodiac longitude and therefore occupies one tropical Sun sign. It cannot be both 29° Cancer and 0° Leo at the same time.

A person may still have other planets in neighboring signs, which can create a mixture of symbolic themes in a full natal chart. That is different from being born with two Sun signs.

How to Confirm a Cusp Birthday

To confirm a cusp birthday, calculate the Sun's zodiac longitude using the birth year, local birth time and birthplace. An accurate ephemeris or natal-chart calculation can determine the sign at the exact moment of birth.

The process involves four steps:

1. Record the full birth date, including the year.
2. Find the local birth time, ideally from a reliable record.
3. Identify the birthplace to establish the correct time-zone context.
4. Compare the birth moment with the Sun's entry into the next sign.

If the Sun entered Leo at 19:13 UTC on a particular July 22, a birth earlier that day in UTC would still fall in Cancer. A birth later would have Leo as the tropical Sun sign.

The time-zone conversion matters because 19:13 UTC corresponds to a different local clock time in New York, London or Sydney.

Tropical vs. Sidereal Zodiac: Why Some Signs Differ

Tropical and sidereal astrology use different reference systems, which can lead to different Sun-sign classifications for the same birthday. Most familiar Western horoscope dates use the tropical zodiac.

The tropical system measures signs from the March equinox, maintaining a fixed relationship with the seasonal cycle. Sidereal systems use a reference tied more closely to stellar positions, with an offset known as the ayanamsa.

Because Earth's axis undergoes precession, the two systems do not assign identical zodiac longitudes to the same celestial positions.

Someone identified as Aries in tropical astrology may therefore receive Pisces in a sidereal chart, depending on their birth details and the selected sidereal convention.

Neither system should be confused with modern astronomical constellations, which have unequal boundaries.

Zodiac Signs Dates vs. Constellation Dates

Zodiac signs dates and the dates when the Sun appears in astronomical constellations are not the same thing. Tropical signs divide the ecliptic into twelve equal sections, while constellations are irregular regions of the sky.

The International Astronomical Union recognizes official constellation boundaries. Along the Sun's apparent path, those regions include Ophiuchus in addition to the twelve names familiar from astrology.

This does not automatically create a thirteenth tropical zodiac sign. Tropical astrology is defined by twelve equal 30-degree sectors, so Ophiuchus belongs to a different astronomical classification.

The confusion occurs when a list of constellation dates is presented as if it were a revised horoscope calendar.

How Zodiac Signs Dates Relate to Birth-Chart Compatibility

Zodiac signs dates identify a person's approximate Sun sign, but full relationship astrology examines additional planetary placements. Two people with the same Sun sign can have different Moon, Venus, Mercury and Mars positions.

For example, someone born under Leo may have a Moon associated with a preference for emotional stability and Venus in a sign traditionally connected with independence. Another Leo may have completely different placements.

A Sun-sign calculator can compare traditional zodiac categories, but it cannot reconstruct the entire relationship between two natal charts.

Frequently Asked Questions About Zodiac Signs Dates

What are the dates for all twelve zodiac signs?

The conventional zodiac signs dates begin with Aries around March 21–April 19 and continue through Pisces around February 19–March 20. The complete table near the beginning of this guide lists all twelve ranges. The actual solar transition dates can vary slightly by year and time zone.

Are zodiac sign dates exactly the same every year?

Zodiac sign dates are approximate and do not switch at the same local midnight every year. Solar ingresses occur at specific astronomical moments, while the civil calendar and time zones determine the displayed date. Birthdays close to a transition require a more precise calculation.

Why do some zodiac charts use March 20 for Aries?

Some charts use March 20 because the Sun often enters tropical Aries on that date. Other popular tables use March 21 as a simplified conventional start. The correct result for an individual birth depends on the actual solar position.

What is the first zodiac sign?

Aries is the first sign of the Western tropical zodiac because it begins at the March equinox. The sequence continues through Taurus, Gemini and the remaining signs until Pisces. The order is based on zodiac longitude rather than the January start of the Gregorian calendar.

Can a person have two zodiac Sun signs?

A person has one tropical Sun sign at a specific birth moment, even when born near a sign boundary. The informal term cusp does not create a double Sun sign. Other planets can occupy neighboring signs, but those are separate placements.

Does a leap year change your zodiac sign?

Leap years can affect the calendar date of a solar transition, but they do not automatically change everyone's Sun sign. A person born on February 29 is normally Pisces in the tropical system. As with other dates, exact solar position determines the sign.

Is Aquarius a water sign?

Aquarius is an air sign in traditional Western astrology despite being represented by the Water Bearer. Cancer, Scorpio and Pisces are the three water signs. The symbols and element classifications are separate parts of the zodiac tradition.

Is Ophiuchus the thirteenth zodiac sign?

Ophiuchus is an astronomical constellation crossed by the Sun's apparent path, but it is not one of the twelve tropical zodiac signs. The tropical zodiac uses twelve equal sectors measured from the March equinox. Adding Ophiuchus would describe a different system.

Which zodiac system should I use?

The familiar Western zodiac signs dates generally refer to tropical astrology, while sidereal astrology uses a different stellar reference. Choosing a system depends on the astrological tradition being followed. For a consistent reading, do not mix dates and interpretations from different systems without explaining the distinction.

Final Thoughts: Your Zodiac Sign Begins With a Date, Not a Stereotype

Zodiac signs dates provide an accessible way to explore the traditional twelve-sign calendar. The familiar ranges help most readers identify their Sun sign quickly, while year-specific solar ingresses resolve birthdays close to a transition.

A Sun sign can introduce traditional symbolism, ruling planets, elements and modalities. It cannot determine personality, predict life events or establish whether someone will be a good relationship partner.
