oh sure, if you subscribe to that nasty, tired, old, worn-out
gregorian calendar prototype... :) [good eye.]

first discrepancy, since 1901, would be 29 feb 2100. (and the
whole y%400 y!%100 y%4 paradigm will need revision anyway
somewhere around 2800 or so, depending on your parameters).
lifetime of this project is unlikely to be a decade, certainly
not a century. not worth the excess computing cycles, methinks,
certainly not for my situation.

still, you win the prize for first eyeball. :)
