It's hard to go anywhere without running into horoscopes using astrology to supposedly advise you or predict future things, based upon your birth sign. Astrology is a form of divination (Defined: https://www.youtube.com/watch?v=DpAIDgEJwB4), which the Bible strongly warns against and condemns!
The Bible has interesting things to say about the stars and constellations. But it also says were are only to seek answers in God, as He desires to show us - or not. Seeking answers elsewhere can open one up to the influence of the demonic.

Also, from Gotquestions.org:
The Bible expressly forbids divination, sorcery, and hidden arts (Deuteronomy 18:10-14). God’s people are to heed God only (Deuteronomy 18:15). Any other source of guidance, information, or revelation is to be rejected outright. (See also Acts 16:16-18.) The Bible points to Jesus Christ as the only proper focus of faith (Acts 4:12; Hebrews 12:2). Our trust is in God alone, and we know that He will direct our paths (Proverbs 3:5-6). Faith in anything besides God is misplaced.
Astrology, then, opposes biblical teaching in at least two ways: it advocates faith in something other than God, and it is a form of divination. We cannot determine God’s will for our lives through horoscopes. As Christians, we are to read the Bible and pray to God in order to gain wisdom and guidance. Consulting a horoscope is a violation of God’s means of communicating with His children. We strongly believe that horoscopes should be rejected by Christians.
Note also, scientifically, the idea that the ancients somehow figured out how star patterns (arbitrarily drawn by connecting key stars in the night sky) supposedly influence our futures and present per our birth dates and the constellations is TOTALLY refuted by astronomy. The earth has a slight wobble to its orbit around the sun. The sun, moon, and planets place a gravitational pull on the earth, causing it to wobble as it spins along its orbit around the sun. But it takes ages to make one complete wobble, to the tune of 25,800 years. And what this means is that NO supposed system of charting the impact of one's birth per the stars could ever be accurate - AS IT'S ALWAYS CHANGING, over time.
