What's my sun sign?

Your sun sign is the zodiac sign the Sun was in on the day you were born. It's the sign horoscopes go by, and the one most people mean when they say "I'm a Leo". Put in your birth date and we'll work it out for the exact year, not from a generic list of dates.

Your sun sign is one part of your chart. Your Moon sign and rising sign change how it shows, which is why two people with the same sun sign can be nothing alike. Your whole chart shows all three.

Why the dates move from year to year

Lists of sun sign dates are averages. A year is about 365 and a quarter days long, so the moment the Sun crosses into a new sign drifts by up to a day from one year to the next, and leap years pull it back. The Sun entered Leo on 22 July in 2026, but on 23 July in plenty of other years.

Time zones add another day of wobble. The change happens at one instant worldwide, which falls on different calendar dates in Sydney and in Los Angeles. If you were born within a day of a change, the calculator says so, and the exact answer needs your birth time and place.

There's no such thing as a cusp sign

If you were born on the edge, you aren't half one sign and half the other. At the moment you were born the Sun was in one sign or the other, and an exact calculation settles which. What's true is that some charts carry a lot of the neighboring sign through other planets, and that's worth knowing, but it comes from the rest of the chart, not from the date.
