What was the point of this? Doesn't the Old Testament say the "Amalekites" were supposedly destroyed; including even their women, children, and donkeys being exterminated? As for when the unrelated people, on the list of the relatively modern historical figures you mentioned, died what does that have do with anything? And I fail to see any supposed "pattern" or anything as that seems to be what this section was trying to imply or something I assume. Also there are many Jewish holidays that span the calendar so different historical figures, who are obviously going to die anyway, are quite unsurprisingly and uneventfully going to die "close" (a relative term as it is) to any of these many possibilities on different calendars.
