What day *should* I have been born on?

You were born exactly when you *should* have been born, in all your contradictory willfulness. The universe doesn't make mistakes. As stated, there are many planetary influences that make up a chart and all will be accounted for when you have a natal (birth) chart done especially for you. I'm thinking lots of Leo because of your preoccupation with yourself. And your need to tell complete strangers about it.
