Why did dates change from BC to AD?

What year AD are we?

What year would it be without BC and AD?
Everything is dated before or after the putative year zero. Thus, BC (or, BCE) dates backward from the year zero, and AD (or CE) dates forward from the year zero. Thus 323 BC/BCE would be 323 years before the year zero, and 323 AD/CE would be 323 year after the year zero.
