Feb 10 Chinese new year
How do you work out the animal you get for when you are born?
The Wikipedia page has a handy chart with the exact dates, which will give you what you're looking for (well, assuming you're not over 100 years old).

Most charts you see just base it on the year (eg - 2024 -> Dragon), but since the lunar new year doesn't start on January 1, if you're born within the first 7-ish weeks of the year, that won't necessarily give you the right answer.
