When was Paris from Romeo and Juliet born?

Romeo and Juliet is not a true story. These people are a fiction. They are made up. They didn't really live. Therefore people only have birthdays if the author tells us so. The author tells us what day Juliet was born on and how long before the story in the play takes place. He does not provide this information about anyone else. Apart from the fact that Juliet's mother calls him "young Paris" (which as far as we know could mean that his father is also called Paris) we have no clue as to Paris's age and certainly no idea what his birthday was.
