Something which i gained,
Astrology is a Art or Science? Astrology is a Science, it is believed that it is purely a mathematical calculations and super guessing, associated with past experiences. In olden days there is no Digital clock, but people see the sky and tell the time, people are so brilliant and stress less, so they had enough time to do research and predict things, the predictions were developed in the later stages and they converted in to writings in the palm tree leaves. our mind is a supercomputer which is equal to 100 systems, but we are becoming lazy and we dont give work to our brains, anything which is not been used properly and regularly will get rusted. Our minds are all rusted now, otherwise we dont want to depend some one to know abut our life and future.
The answer for your quewtion, Astrology is an beautiful art too. It can be believed, if you are approaching a good astrologer and not a money minded person. Believe astrology, but dont depend on astrology. Because You have everything in you to Make it or Break it.
