Your sun sign is the zodiac sign the Sun was passing through on your birthday. It describes your core identity, your ego, and what you are growing into over a lifetime. It is the sign horoscopes are written for, and it is one piece of a much bigger chart.
What your sun sign describes
The Sun is the center of the solar system and the center of your chart. Your sun sign is your sense of self: your drive, your pride, the qualities you grow into as you become more yourself. It answers the question underneath most others, which is who am I actually here to be.
It takes the Sun about a month to cross each sign, so your birthday alone sets it. That is why sun signs are the one part of astrology almost everyone knows about themselves.
Why your sun sign is only the start
A sun sign is real, but it is one planet. Your moon runs your feelings, your rising runs your first impression, Venus runs how you love, Mars runs how you go after things. A full chart has all of them, which is why two people with the same sun sign can feel like different species.
So when a horoscope misses, it is usually not wrong so much as incomplete. It is speaking to one part of you and staying quiet about the rest.
The dates, and being born on a cusp
Each sign covers roughly a month, but the exact changeover shifts by a day or so from year to year because the calendar and the sky never line up perfectly. If you were born in the day or two where one sign becomes the next, your birth year and even your birth time decide it.
There is no such thing as being half two signs. On a changeover day your Sun is in one sign or the other, and the only way to be sure is to compute it from your exact birth moment.
How to find your sun sign
For almost everyone, your birth date is all it takes. If you were born close to a changeover, add your birth time and place to settle it for certain.

Questions people ask
Is your sun sign your real sign?
It is your most talked about sign, and it is genuinely yours, but it is not the whole of you. Astrologers usually read the sun, moon, and rising together before saying much about a person. Your sun sign is the honest starting point, not the finish line.
Can your sun sign change?
No. The Sun was in one sign at the minute you were born and it stays there for life. What can change is what you believed it was, especially if you were born on a cusp day and only ever guessed from the standard dates.
What is the difference between a sun sign and a star sign?
They are the same thing. "Star sign" is the casual name and "sun sign" is the precise one: both mean the zodiac sign the Sun occupied on your birthday.
Why does my sun sign sometimes feel wrong?
Usually because your moon or rising is loud. A Pisces sun with an Aries rising can read as far more direct than "sensitive Pisces" suggests. When your sign feels off, the rest of your big 3 is often the reason.
