I think the "side note" was added after I wrote. In my experience, the largest two camps of people who look at it put Jesus's death in 30 or 33 AD, and I'd like to say 33 is the larger camp but I can't prove that. There is also a small camp who put his birth in 1 BC. When looking at other views I don't find any that answer all my reasons for proposing exactly 4 and 33 (age 35.5, or 18 months more than OP proposes).
Counterpoint.
