Developing one's one has to be done, or its just someone else's derived understanding.. although seeing what others have done can serve as hints or at least considerations and maybe see where they might have gone off track. Many assumptions will be assumed in such chronologies, many will not lay bare their assumptions so that one may recognize them as Assumptions and not Fact nor 'the truth'.

Many assumptions too about the number of years the Jesus did his ministry, as well as many assumptions as to his birth and the start of his ministry. The externals of the Roman Chronicles seemingly have to be used however there are links within the New Testament to them.

Doesn't hurt however to look at two or more somewhat different approachs, so that one has somethign to contrast them with, and ask further questions of the Scripture itself about them. DOing in solely in the English may be a bit of a reductionist approach..
