June 24th, 1991(in case the birth year makes a difference). Cancer. Hit me with your best shot. :D
Birth year doesn't really make a difference unless you want to use that information to make a natal chart. I particularly enjoy making natal charts as they tell you other information about the circumstances of your birth and seem to be weirdly accurate according to some believers. Basically: it tells you much more than just your sun sign tells you alone.
Anyway, you may be surprised to learn you are not just a Cancer, but actually a Cancer-Gemini cusp! Unlike the other Cancer-Geminis I've read so far, you're closer to Cancer than to Gemini. Perhaps people often comment that you have a good sense of humor? That's a trait that is commonly displayed by this cusp. As you are a cusp, you're technically compatible with air, earth, fire AND water, though not all of those are recommended. For you, my personal recommendations would be Leo, Scorpio and Capricorn. You may also find luck with a Gemini, Libra, Pisces or maybe even a Taurus or Aries.
Can I drop in like waaaaaahey 4th of February, 1998?
where are all the aquariuses at tho
Aquarius seem to be rather common as I've given about three or four readings for them already!
Based on your birthday, you are in the middle arc of Aquarius. Perhaps you are more secretive or eccentric than other Aquarius you might know? That doesn't seem impossible based on your birthday. Like most Aquarius, you would likely be best with Aries, Gemini, Leo and possibly another Aquarius. You may also find luck with Capricorn, Taurus, Libra or Sagittarius.
