New vs old zodiac

Lauren

I don't know much about the newer zodiac, is it more accurate? When did it go into effect? Traditional zodiac says I'm probably having a Leo, but the new one would make it a Cancer. Am I just being stubborn by not wanting to change It? I've always been a stereotypical Libra, I can't imagine identifying as anything else! Should I just wait and have a chart done by a pro?
