Are horoscopes against the bible?

yes, from what I can recall (Haven’t read the bible for a few years) all future telling is considered wrong. (Its tied in with witchcraft etc)

The Hebrew prophets, however, did not reject astrology merely because of its manifest failure to predict the future accurately. The Law that God gave to Moses specifically warned the Israelites against looking for omens. “There should not be found in you . . . anyone who employs divination . . . or anyone who looks for omens,” the Law stated. “Everybody doing these things is something detestable to Jehovah.”—Deuteronomy 18:10, 12.

Although astrology is not mentioned by name in that scripture, the prohibition evidently included the practice. The Encyclopædia Britannica notes that astrology is a “type of divination that consists in forecasting earthly and human events by means of observing and interpreting the fixed stars, the Sun, the Moon, and the planets.” All forms of divination—whether based on the stars or other objects—violate God’s guidelines. Why? There is good reason.

Rather than attribute our successes or failures to the stars, the Bible clearly states that “whatever a man is sowing, this he will also reap.” (Galatians 6:7) God holds each of us responsible for our actions, since we are free moral agents. (Deuteronomy 30:19, 20; Romans 14:12) True, we may suffer an accident or an illness because of events beyond our control. But such calamities, the Scriptures explain, are due to “time and unforeseen occurrence,” not our horoscope.—Ecclesiastes 9:11.

The bible does condemn astrology and divination,

Technically it is

Horoscope opposes the Bible in that it advocates faith in a source other than God and also that it is a form of divination. The Bible prohibits it (Deuteronomy 18:10-14), Evil exists in the world because sin exists, The root of every bad thing is Satan. We cannot underestimate his power and his hatred for mankind. that’s why God warns us to stay away from everything that is not from Him.
