Zodiac Signs Dates by Month: Find Your Sign in Seconds

Someone born on January 5 and someone born on January 25 have the same birth month, but their zodiac Sun signs are different. The first is conventionally Capricorn, while the second is Aquarius. The same pattern appears in every month of the year.

Zodiac signs dates by month provide a practical way to identify a Western Sun sign using the month and day of birth. Rather than starting with the traditional Aries-to-Pisces sequence, the calendar follows the familiar January–December order and shows the two zodiac signs associated with each month.

This is particularly useful for birthdays near the middle or end of a month, when one sign changes into the next. Someone born on July 7 is comfortably Cancer, but a person born July 22 may need the exact birth year and time to determine whether their Sun had entered Leo.

The following guide includes a complete zodiac signs by month chart, detailed explanations of every month, example birthdays, elemental classifications and answers to common questions about cusp dates.

Zodiac Signs Dates by Month: Complete January–December Chart

The zodiac signs dates by month chart shows the two conventional Sun-sign periods within every Gregorian calendar month. The switch dates are approximate because the Sun enters each sign at a specific astronomical moment.

To use this zodiac signs dates by month chart, find your birth month and locate the two corresponding signs. Compare your birthday with the approximate transition.

For most birthdays, the answer is clear. People born well before or after a sign transition rarely need additional information.

However, a birthday on a transition date can belong to either neighboring sign depending on the exact year and time. The conventional table should therefore be treated as a quick lookup, not a substitute for calculating the Sun's actual position.

January Zodiac Signs: Capricorn and Aquarius

January contains Capricorn and Aquarius, with the Sun usually entering Aquarius around January 20. Capricorn occupies the earlier part of the month, while Aquarius covers the final portion.

Capricorn is an earth sign traditionally associated with responsibility, ambition and consistency. Aquarius belongs to the air element and symbolizes independence, intellectual curiosity and unconventional perspectives.

Someone born January 7 is conventionally Capricorn, while someone born January 27 is Aquarius. A birthday on January 19 or 20 deserves additional attention because the boundary can occur at different times.

January Birthday Examples

January is also an interesting month for people comparing Western and Chinese astrology. The Western Sun sign can change around January 20, while the Chinese animal year follows a different calendar boundary.

The two systems should not be confused. A January birthday has a Western Sun sign and may also have a Chinese animal-year classification, but they represent different traditions.

February Zodiac Signs: Aquarius and Pisces

February contains Aquarius and Pisces, with the Sun normally entering Pisces around February 18 or 19. The earlier part of February is conventionally Aquarius, while the later part belongs to Pisces.

Aquarius is a fixed air sign associated with independence and curiosity. Pisces is a mutable water sign symbolizing sensitivity, imagination and reflection.

Someone born February 7 is generally Aquarius. Someone born February 25 is normally Pisces, while February 18 or 19 may require a year-specific calculation.

What About February 29?

February 29 is conventionally a Pisces birthday in Western tropical astrology. The additional leap day does not create a separate zodiac sign, and it does not change the basic twelve-sign structure.

A person born on February 29 remains classified according to the Sun's actual position on their birth date. Since the date falls comfortably within the usual Pisces period, its Sun-sign identification is normally straightforward.

People sometimes assume the leap-year system changes every zodiac boundary automatically. It can affect civil-date alignment, but the astronomical position of the Sun remains the deciding factor.

March Zodiac Signs: Pisces and Aries

March contains Pisces and Aries, with the Sun entering Aries at the March equinox around March 20 or 21. The earlier part of the month belongs to Pisces, while the later part begins the traditional Western tropical zodiac cycle.

Pisces is associated with imagination and emotional sensitivity. Aries is a cardinal fire sign traditionally linked to initiative, action and independence.

A March 8 birthday is conventionally Pisces, while March 29 is Aries. March 20 deserves special attention because the Sun often enters Aries on that date rather than March 21.

Why March Is Different From Other Months

March is significant because the entry into Aries defines the beginning of the tropical zodiac. The zodiac is divided into twelve equal 30-degree sections, starting with 0° Aries at the March equinox.

That means the first zodiac sign of the astrological sequence begins near the end of March rather than on January 1.

For this reason, January and February appear near the end of the astrological sequence even though they come first in the Gregorian calendar.

April Zodiac Signs: Aries and Taurus

April contains Aries and Taurus, with the transition usually occurring around April 19 or 20. Aries dominates the earlier part of the month, while Taurus occupies most of the final third.

Aries is a cardinal fire sign symbolizing initiative and direct expression. Taurus is a fixed earth sign associated with consistency, stability and the enjoyment of tangible experiences.

An April 5 birthday is generally Aries, while April 26 is Taurus. April 19 or 20 may require the exact transition time.

The symbolic difference between the two signs is often described as starting something versus building something lasting. These are traditional archetypes rather than rules about individual personalities.

May Zodiac Signs: Taurus and Gemini

May contains Taurus and Gemini, with the Sun usually entering Gemini around May 20 or 21. Taurus occupies the first part of the month, while Gemini covers the final portion.

Taurus is a fixed earth sign associated with comfort, patience and reliability. Gemini is a mutable air sign traditionally linked to communication, curiosity and adaptability.

Someone born May 10 is conventionally Taurus, while May 28 is Gemini. May 20 or 21 is a transition period requiring more care.

Is May 21 Always Gemini?

May 21 is commonly listed as the first Gemini date, but the exact answer depends on the solar transition in the birth year. A person born before the Sun's entry into Gemini would still have Taurus as their tropical Sun sign.

The correct method is to identify the solar ingress and compare it with the recorded birth moment.

A generic zodiac signs dates by month chart is most useful for quick reference; exact boundary dates require an astronomical calculation.

June Zodiac Signs: Gemini and Cancer

June contains Gemini and Cancer, with the Sun entering Cancer near the June solstice around June 20 or 21. Gemini covers the earlier portion of the month, while Cancer begins around the seasonal transition.

Gemini is a mutable air sign associated with communication and flexibility. Cancer is a cardinal water sign traditionally connected to nurturing, emotional security and familiarity.

A June 6 birthday is generally Gemini, while June 28 is Cancer. June 20 or 21 can be a boundary case.

The transition into Cancer is especially important within the tropical zodiac because it corresponds to the June solstice. It is one of four seasonal anchor points used in the system.

July Zodiac Signs: Cancer and Leo

July contains Cancer and Leo, with the Sun generally entering Leo around July 22 or 23. Cancer occupies most of the month, while Leo begins during the final portion.

Cancer is traditionally associated with sensitivity and close personal connections. Leo is a fixed fire sign symbolizing creativity, warmth and expressive confidence.

Someone born July 8 is conventionally Cancer, while July 30 is Leo. July 22 and 23 may be more complicated because the exact transition can fall on either local date.

Is July 22 Cancer or Leo?

July 22 can be Cancer or Leo depending on the birth year and exact moment. In 2026, for example, the Sun entered Leo on July 22 at approximately 19:13 UTC.

A person born before that moment in the same year had the Sun in Cancer. Someone born afterward had the Sun in Leo.

Time zones can make the local calendar date of this transition appear differently in different countries, so the full birth details matter.

August Zodiac Signs: Leo and Virgo

August contains Leo and Virgo, with the Sun normally entering Virgo around August 22 or 23. Leo covers the earlier part of the month, while Virgo occupies its final days.

Leo is a fixed fire sign associated with creativity and appreciation. Virgo is a mutable earth sign symbolizing observation, practical care and attention to detail.

An August 9 birthday is conventionally Leo, while August 29 is Virgo. August 22 or 23 is near the usual transition.

The difference between the two traditional archetypes can be described as expressive creativity versus careful refinement. Neither description reliably determines a person's actual character.

September Zodiac Signs: Virgo and Libra

September contains Virgo and Libra, with the transition occurring near the September equinox around September 22 or 23. Virgo dominates the earlier portion, while Libra covers the last part of the month.

Virgo is a mutable earth sign traditionally associated with thoughtful organization. Libra is a cardinal air sign linked to cooperation, fairness and shared decision-making.

Someone born September 10 is conventionally Virgo, while September 29 is Libra. September 22 or 23 is the important boundary period.

Why September 22 Can Be Libra

September 22 can be Libra in some years and time zones because the Sun enters Libra at a precise moment around the September equinox. The transition is not tied permanently to September 23 at midnight.

In 2026, the Sun entered Libra shortly after midnight UTC on September 23. In parts of North America, the same instant occurred on the evening of September 22.

Two people born on the same local calendar date in different locations may therefore need their birth times and time zones checked carefully.

October Zodiac Signs: Libra and Scorpio

October contains Libra and Scorpio, with the Sun normally entering Scorpio around October 22 or 23. Libra occupies the first part of the month, while Scorpio dominates the final days.

Libra is associated with partnership and balanced communication. Scorpio is a fixed water sign traditionally linked to privacy, determination and emotional depth.

Someone born October 12 is conventionally Libra, while October 30 is Scorpio. October 22 or 23 is near the transition and should be checked individually.

October birthdays also demonstrate why neighboring signs can have very different symbolic categories. Libra belongs to air and the cardinal modality, while Scorpio belongs to water and the fixed modality.

November Zodiac Signs: Scorpio and Sagittarius

November contains Scorpio and Sagittarius, with the Sun usually entering Sagittarius around November 21 or 22. Scorpio occupies most of the earlier part, while Sagittarius covers the end of the month.

Scorpio symbolizes emotional depth and determination, while Sagittarius is a mutable fire sign associated with exploration, learning and personal freedom.

A November 10 birthday is normally Scorpio, while November 29 is Sagittarius. November 21 or 22 may be a boundary date.

Is November 22 Always Sagittarius?

November 22 is often Sagittarius, but the exact answer depends on the solar entry time for the birth year. The Sun may enter Sagittarius during that date, leaving earlier births in Scorpio.

This is why generic monthly zodiac charts sometimes disagree with personalized natal-chart calculations.

The correct approach is to compare the recorded birth moment with the corresponding astronomical transition.

December Zodiac Signs: Sagittarius and Capricorn

December contains Sagittarius and Capricorn, with the transition near the December solstice around December 21 or 22. Sagittarius covers the earlier part of the month, while Capricorn occupies the final portion.

Sagittarius is a mutable fire sign traditionally associated with independence and curiosity. Capricorn is a cardinal earth sign linked to responsibility, persistence and planning.

Someone born December 8 is conventionally Sagittarius, while December 29 is Capricorn. December 21 or 22 is a significant boundary.

In 2026, the Sun entered Capricorn on December 21 in UTC. This is one reason why older or simplified date charts can classify certain December birthdays differently.

Zodiac Signs Dates by Month: Birthday Examples

Birthday examples make zodiac signs dates by month easier to use because most readers are looking for a specific day rather than an abstract calendar range. The following examples fall safely away from the usual sign transitions.

The examples avoid the dates most likely to fall on a solar transition. For a boundary birthday, the correct sign must be calculated using the relevant birth year.

Why Does Every Calendar Month Have Two Zodiac Signs?

Every Gregorian calendar month normally contains parts of two tropical Sun-sign periods because the zodiac cycle begins around March 20 and its boundaries do not align with the first day of each month. The twelve zodiac sections occupy equal 30-degree intervals, while civil months have different lengths and fixed calendar starts.

For example, January begins while the Sun is in Capricorn and continues into Aquarius. February begins with Aquarius and later changes to Pisces.

The relationship between zodiac signs and months is therefore approximate rather than one-to-one. January is not a Capricorn-only month, and August is not exclusively Leo.

This explains why a person's birth month alone is insufficient for identifying the Sun sign.

How to Check a Birthday Near a Zodiac Sign Boundary

A birthday near a zodiac transition requires the year, exact time and birthplace to determine the tropical Sun sign reliably. A standard zodiac signs dates by month chart is not precise enough for every cusp date.

The process is straightforward:

1. Record the complete birth date, including the year.
2. Find the birth time from a reliable source where possible.
3. Identify the birthplace and its time-zone context.
4. Look up the solar ingress for the relevant year.
5. Compare the birth moment with the Sun's entry into the next sign.

A birth before the solar ingress belongs to the previous sign. A birth after the ingress belongs to the new sign.

This is an astronomical calculation within the tropical zodiac system, not an interpretation of personality. It can provide a precise sign placement without establishing anything about someone's behavior.

Zodiac Sign by Month vs. Moon Sign and Rising Sign

A Sun sign identified from the birth month is not the same as a Moon sign or rising sign. These placements depend on different astronomical positions and may belong to different zodiac signs.

The Sun takes approximately one year to move around the tropical zodiac. The Moon changes signs roughly every two to two and a half days, while the Ascendant changes much more quickly as Earth rotates.

A person born in August may have Leo or Virgo as a Sun sign but a Moon in another sign entirely. Their rising sign depends strongly on the exact birth time and location.

This distinction matters when readers use a simple zodiac signs dates by month chart as though it represented an entire natal chart.

How Birthday Months Connect to Zodiac Compatibility

Zodiac signs dates by month can identify two people's approximate Sun signs for a traditional compatibility comparison, but they do not establish how the relationship will develop. The Sun sign is only one of several factors examined in astrological synastry.

For example, someone born April 7 and someone born August 10 are conventionally Aries and Leo, both fire signs. Traditional astrology describes that elemental relationship as harmonious.

Another couple born April 7 and July 10 would be Aries and Cancer, a square relationship by sign. That does not prove a less successful relationship; it simply represents a different symbolic category.

Frequently Asked Questions About Zodiac Signs Dates by Month

What are the zodiac signs dates by month?

Each month contains two conventional zodiac Sun signs, with a transition usually occurring between the eighteenth and twenty-third day. The complete January–December chart above lists the pairs and approximate boundary dates. Exact transitions vary with the year and time zone.

What zodiac signs are in January?

January includes Capricorn and Aquarius. Capricorn normally continues through approximately January 19, while Aquarius begins around January 20. A boundary birthday may require checking the year-specific solar entry.

What zodiac signs are in February?

February includes Aquarius and Pisces. Aquarius occupies the earlier part of the month, while Pisces generally begins around February 18 or 19. February 29 is normally Pisces.

What zodiac signs are in July?

July includes Cancer and Leo. Cancer continues until approximately July 22 or 23, while Leo covers the final part of the month. The exact transition may occur on July 22 in some years.

Can one month contain three zodiac signs?

A normal Gregorian month does not contain three separate tropical Sun-sign periods within the standard twelve-sign sequence. The Sun generally spends about a month in each sign. Consequently, each civil month overlaps portions of two neighboring zodiac periods.

What zodiac sign is someone born on the 20th?

The twentieth day is a transition date in several months, so the month, year and sometimes birth time determine the answer. January 20 may be Capricorn or Aquarius, April 20 may be Aries or Taurus, and May 20 may be Taurus or Gemini. A universal rule for all twentieth-day birthdays would be inaccurate.

Why do some websites give different dates?

Different sites may use conventional birthday ranges or calculate exact solar transitions. The displayed date can also depend on the time zone. Tropical and sidereal zodiac systems introduce a separate source of differences because they use different reference points.

Does the birth month determine someone's personality?

The birth month does not scientifically establish personality characteristics. Astrological descriptions associate symbolic themes with Sun signs, but they should not be treated as individual diagnoses or factual predictions.

Final Thoughts: Find Your Month, Then Check Your Moment

Zodiac signs dates by month offer one of the quickest ways to identify a Western Sun sign. The January–December format is especially useful when readers know a birthday but are unfamiliar with the traditional Aries-to-Pisces sequence.

For most birthdays, the conventional calendar provides a clear result. For dates near a sign change, the birth year and exact solar ingress make the difference between a rough estimate and a properly calculated tropical Sun sign.
