Miscalculation

 Lucius Shephard posts this link, a site replete with further predictions, and which explains (to me, anyway, for the first time) the almost ludicrously baseless arithmetic of Camping.  Sophisticated mathematicians have spent years on these matters, and (though of course all wrong too) far outshine old Harold in ingenuity, not to say hard work.  Th e Naometria of "Simon Studion" (1604) runs to a couple thousand pages.

But looking at this site it occurred to me -- do predicters of exact dates using info out of the Bible abd counting forward to this month or year take into account the correction of the Gregorian calendar in the 18th century by which some nujmber of days (15?) were lost or discarded?  Maybe, remembering that, Harold can add a couple weeks to his account.
