Mainstream astrology, no. Most horoscopes you'll find on the internet are based on the zodiac sign that your sun was in on the moment you were born. But when you dig deeper, do a natal chart for example, you will get a pretty accurate description of who you are.
It will show you the zodiac signs all of the planets in our solar system on the exact minute you were born. Different planets rule different aspects of your personality.
The sun, for example, is the planet of the Self. The moon = emotions. Venus is the planet of love and relationships. Mercury is the planet of communication. Mars is the planet of action, and so forth.
From a scientific standpoint, it IS in my eyes plausible too, when you take into account how much the moon alone influences the tide of the ocean here on Earth. We are beings made of water, and our brains are encased in water. Why SHOULDN'T the planets at that time influence that? We have no way of measuring that yet either, so nobody can say it's fake or real. Dig deeper into astrology than your newspaper or internet horoscopes on buzzfeed/whatever, you'll find it to be very interesting
