To presuppose that knowledge is either good or bad, preempts GOD's divine prerogative.
As it is, I would argue that where Scripture discounts knowing the DAY and the HOUR, it does not discount the week, month, season, year, etc. Furthermore, I would observe that knowing the year is elementary, and the season obvious. And if someone were well versed in the significance of the feasts, one could reasonably arrive to the week.
But if the church elects to remain ignorant, who am I to disrupt that "bliss".
