Being a noob to collecting lunars I was going on the birth year to determine my animal. But wait I have just discovered the lunar year doesnt start on the 1 january (big derrr moment I know). So check it out if you were born in Jan or Feb your lunar animal may not be what you thought. http://www.honeylim.com/articles/animal-sign/
Thats a very good point hiho. I personally was aware of it. I was getting a tattoo and wanted my animal sign incorporated somehow. Needless to say I made sure I researched that properly before hand
