Sariel doesn't really believe in the fortune-telly, horoscope-y end of things. She's familiar with enough cultures, Terran and otherwise, that the concept of any very narrow zodiac is a bit strange to her. add in the whole space travel thing, and... yeah, she doesn't think much about horoscopes. If someone else does, that's up to them, but she'll leave the idea alone, thanks.

Incidentally, I've set her birthday as June 9, since canon never said.
