What is a Sun sign?
The Sun at your birth
Your Sun sign is the tropical zodiac sign occupied by the Sun at your exact birth moment. It is the placement usually meant by the familiar term zodiac sign.
Why cusp dates need calculation
The Sun enters a new sign at a specific time that shifts slightly from year to year. If you were born near a boundary, a fixed date table can be wrong, while an ephemeris calculation uses your actual birth moment.
One center, not the whole chart
The Sun is important, but the Moon, Rising sign, planets, houses, and aspects explain emotional needs, visible style, relationships, timing, and the specific life areas where solar identity develops.

Questions, answered
Sun Sign Calculator FAQ
Is my Sun sign the same as my zodiac sign?
Usually, yes. In popular Western astrology, zodiac sign or star sign normally refers to the tropical Sun sign calculated for your birth moment.
Can my Sun sign be wrong if I was born on a cusp date?
A fixed date table can be wrong near an ingress because the Sun changes signs at a precise time that varies by year. Your actual birth time and timezone resolve the boundary.
Do zodiac cusps create a blended Sun sign?
The Sun has one exact zodiac longitude and occupies one sign at any moment. Nearby planets or other chart placements may resemble the neighboring sign, but the Sun itself is not split between two signs.
Do I need my birth time for my Sun sign?
Most birthdays can be identified from the date, but an exact time is important on a sign-change day and is required to calculate the Sun's reliable house placement.
