Does the Bible condemn astrology?

Yes, the Bible condemns astrology.

There are two passages that are often quoted to show that the Bible condemns astrology, although it depends on what is meant by using "enchantment", "divination", and "observing times".

Neither shall ye use enchantment, nor observe times. Leviticus 19:26
There shall not be found among you any ... that useth divination, or an observer of times.... For all that do these things are an abomination unto the LORD. Deuteronomy 18:10-12

Some of the prophets spoke harshly of astrologers, stargazers, readers of the signs of heaven, and those who worship the host of heaven.

Let now the astrologers, the stargazers, the monthly prognosticators, stand up, and save thee from these things that shall come upon thee. Behold, they shall be as stubble; the fire shall burn them; they shall not deliver themselves from the power of the flame: there shall not be a coal to warm at, nor fire to sit before it. Isaiah 47:13-14
Thus saith the LORD, Learn not the way of the heathen, and be not dismayed at the signs of heaven; for the heathen are dismayed at them. Jeremiah 10:2

I will cut off ... them that worship the host of heaven. Zephaniah 1:4-5

No, the Bible approves of astrology.

God created stars, in part, to serve as "signs" -- which is how they are used in astrology.

And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years. Genesis 1:14

When God inspired Jael to pound a tent stake through the sleeping Sisera's skull, he did so with the help of the stars.

The stars in their courses fought against Sisera. Judges 5:20

When Jesus was born, "wise men" (astrologers?) saw his star.

Now when Jesus was born in Bethlehem of Judaea in the days of Herod the king, behold, there came wise men from the east to Jerusalem, Saying, Where is he that is born King of the Jews? for we have seen his star in the east, and are come to worship him. Matthew 2:1-2

And Jesus said there woud be "signs" in the sun, moon, and stars to proclaim the end of the world.

And there shall be signs in the sun, and in the moon, and in the stars. Luke 21:25
