If BC was before Christ and AC was after Christ what do you call the years he was alive?

Before the Birth of Christ and After the Birth of Christ. Usually the two abbreviations are BC (Before Christ) and AD (Anno Domini - In the Year of Our Lord) When the year of Christ's birth was recorded there was an error made in the dates, because, after some time, it was realised that Christ was actually born a few years earlier than they thought. So we now know that Christ was born around 3 or 4 BC. Another problem was that there was no year '0', so 1 BC was followed by 1 AD. Therefore, if the crucifixion and resurrection took place when Christ was 33 (as stated in the Bible) and he was born around 3 or 4 BC, then the crucifixion and resurrection took place around 30 AD, as the measurement of the date was taken from the time of Christ's birth and not his whole earthly life.
