I only know because some times I'm a rabbit and other times I'm a Tiger.
it was confusing... so I researched it a bit.

a lot of times in the Western World they use the 'gregorian new year' instead of the chinese new year to say what you are - because they are very close... but if you are born in the first 6 weeks of the year Jan-Feb - you should check when the Chinese New Year actually is, because you may belong to the previous year.
