Well, your Sun sign is Aquarius. 'Zodiac' sign is the same, that's just the label to name the signs collectively-they are all part of the 'zodiac'.
However you are a unique because even though many have their Sun signs in Aquarius, your Ascendant, Moon sign, Mercury sign etc will all fall in different houses in your chart and have different signs on the cusps.
So, imagine a whole pie, sliced into 12 pieces, yet each is individually flavored lol...no two pies would be the same if each is flavored by a different 'sign' so to speak.
Well, it's good you know your birth time, but you also need your place of birth-city & state-to find out your Ascendant, and also in your case-your moon sign as it was changing signs that day from Virgo into Libra-so it's one of the two. Also, Mercury was changing signs that day too, so your communication sign is either in Capricorn, or Aquarius.
Things I can tell you right now without your birth time;
Wow, okay, for starters-your Venus, Mars, Uranus, Neptune, and Saturn are all in Capricorn.
Your Jupiter is in Cancer.
Mercury(your communication sign) is either in Capricorn, or Aquarius(as it switched into Aquarius on the 13th), but you would need more birthdata(city&state) to be sure.
You have a lot of planets in Capricorn-an earth sign, so don't be surprised when you read general horoscopes for Aquarius and things just never seem to 'fit'.
Your north node is in Aquarius.
I could go on, but for a more in depth description-go to www.astro.com and create an account. From there, you can choose 'free horoscopes', and in it you will find alot of options. To learn even more, click on 'interactive horoscope'. Without the city&state, I can only say what planets were in the signs on that day, but not where they fall in your chart-what house. Each house represents a different part of you....etc etc..
Have fun!
