Queer Questions and Wonders

Jesus

I have a question about Jesus and no it is not about how he was resurrected. I want to know when he was born. If it was 1 B.C., it would be strange since he couldn't have been born a year before he was born.

If it is 0 A.D. it would be strange because A.D. is the intials for the Latin words that mean, in the time of our Lord. If it means in the time of our Lord how could he be born in 0 A.D.

If it is 1 A.D. wouldn't it mean a year after the time of our Lord which would mean he would've been born already. This is really troublesome to me so please tell me.

Research it on the internet, Bible, etc. Just comment and tell me your answer.
