I tend to agree with Boanerges with regard to Jesus age. I'll pull up some substantiation for that and post it.
Just for a quick starter, the calendar used was nearly as flawed as the one we use today, hense the need to throw in a day here and there to balance it out.
Also, some have mistakenly added a "Year Zero".
There was not year "zero".
These and several other errors in dating have created a slight discrepancy over time.
I wrote an essay in which I was able to substantiate the earliest gospel, (Mark) as being recorded within 35 years of Jesus ministry, not the hundred year theory that some have proposed.
As soon as I dig that up on my computer I will post some solid arguments and sources for this.
