Understanding your sun sign
Your sun sign is the zodiac sign the Sun occupied on the day you were born. The Sun spends about a month in each sign, so unlike the Moon or rising sign it can be found from your birth date alone — which is why it's the sign you read in horoscopes and the one most people identify with.
The Sun represents your core identity: your ego, willpower, vitality, and the conscious self you grow into over a lifetime. Where your moon sign describes your private emotional world and your rising sign the impression you make, the Sun is the steady centre — the values and sense of purpose you express most fully when you feel like yourself.
If you were born within a day or two of a sign change — on a 'cusp' — your birth time can determine which sign the Sun was actually in, since the Sun changes signs at a precise moment. Our calculator pins down your exact Sun sign and degree, and pairing it with your Moon and rising signs completes the 'big three' at the heart of your chart.
