Born on the edge
of two signs?
Let's settle it.

What this is

Your birthday. That's all.

Your star sign is decided by where the Sun was in the sky at the moment you were born. Most sites look that up in a fixed table — "Aries: March 21 to April 19" — but those dates move. The Sun crosses into Aries at a slightly different hour every year.

So if you were born on a changeover day, half the internet has been telling you the wrong sign. We calculate the actual moment instead. If your birthday is close to a boundary, add your birth time and we'll get it to the minute.
