Zodiac Signs by Date
What is my zodiac sign by birth date?
Your zodiac sign by birth date usually means your tropical Sun sign: the sign the Sun occupied when you were born. Match your birthday to the 12 standard date ranges below. Most dates map clearly to one sign, while a birthday near a changeover may depend on the birth year, exact time, and birthplace because the Sun changes signs at a specific moment. Your Sun sign is one part of a complete natal chart.

What happens on a zodiac-sign changeover date?
A changeover date is the day the Sun moves from one tropical zodiac sign into the next. The exact moment can shift slightly with the year and time zone, so two people born on the same calendar date can have different Sun signs. A so-called cusp is not a third or hybrid sign: the Sun is in one sign at the recorded birth moment. Use your exact birth details when the date is near a boundary.
Is a star sign the same as a Sun sign?
In everyday horoscope language, star sign usually means Sun sign. It describes the zodiac sign occupied by the Sun at birth. A complete natal chart also includes the Moon, Rising sign, planets, houses, and aspects, so it provides more context than a Sun-sign label alone.
Do I need my birth time to know my zodiac sign?
You usually do not need a birth time for a basic lookup when your birthday falls well inside a standard range. Birth time, year, and birthplace matter on a changeover date, and an exact time is also needed to calculate the Rising sign and houses in a full natal chart.
Your Sun sign is not your whole birth chart
Astrology uses the Sun sign as one interpretive placement, not a deterministic description of a person. Zodigram calculates Astrology, Human Design, and Gene Keys from the same birth details so you can explore how the three systems connect for reflection and self-discovery.
How to use these date ranges
The table preserves the 12 date ranges already used in Zodigram sign content and presents them as standard tropical Sun-sign ranges.
Calendar lookup is suitable for most birthdays. Boundary dates should be checked with the birth year, exact time, and birthplace because the solar changeover occurs at a particular moment.
Astrology is an interpretive tradition. This guide does not claim scientific causation, predict outcomes, or provide medical, psychological, legal, or financial advice.

What does it mean to be born on a zodiac cusp?
Cusp is a common name for a sign-change date, but it is not a third or hybrid zodiac sign. The Sun occupies one sign at the birth moment, which is why year, time, and birthplace can matter on a boundary date.

Do I need my birth time to know my zodiac sign?
Not for most dates, but an exact birth time can decide the Sun sign on a changeover date. It is also needed to calculate the Rising sign and houses in a complete natal chart.
