I'm a Gemini six ways to Sunday, but the way I approach those fields (numerology, etc.) is to use it as sort of a sounding board or perhaps a "chart" of personality characteristics to try on and see if they fit. The daily horoscope stuff I'm not so much into.
An individual's astrological "sign," as
most of think of it, is actually just one of many signs that comprise the individual's chart. In your case, Leo is your sun sign, which represents the core of your identity. Archtypes are the king, performer, child & clown. Self expression is the keyword for Leo. If you were born within a day or so of Cancer or Virgo, those characteristics may apply.
You also have a moon sign which represents your soul's urge. Sort of whatever inner longing you have for yourself. Your moon sign might be Taurus or Piesces or Leo depending on where it was located in the sky when you were born. Consequently, your soul's urge might have those traits. Finally (in today's lesson), you have a rising sign (again Taurus, Libra, what have you) that was "dawning" in the sky when you were born. This represents your persona, how you first appear to others. The trinity, if you will, are the three primary signs, but there are about nine or ten others in a full chart, each with their own influence.
Back to your question (ha!) the daily stuff in the paper is probably based only on what's going on with the sun sign and obviously cast a pretty wide net.
