Producing an accurate horoscope involves not just your date of birth, but year, time and place. Most people go entirely by their sun sign, completely disregarding - if they are even aware of - the fact that there is also a moon sign to consider, as well as one for the other 8 planets in the solar system, an ascendent or rising sign, and a midheaven sign. There's no way - unless it's been plotted particularly for you - that a horoscope can even hope to be accurate (except by chance). Even so, my specifically plotted one today tells me both that I'm pretty much going to be a sarcastic cow to everyone I meet (though now that I think of it I was pretty sarcastic to the other half this afternoon - but he's not everyone), and that my mind will be particularly sharp. So sharp I couldn't even remember my own phone number this afternoon. September 13th mentioned the chance of a new romance (I haven't finished with the old one yet), but neglected to inform me that the guy whose landscaping we had just finished the previous Friday would then refuse to pay for it.
I thought that was rather lax of it not to have picked that tidbit out of the stars.
