None will no the day and hour. But could someone know the week or month or year or decade or century?
We can know the season...
LOL. I don't know if you were serious in your inquiry or not, but this is the precise, twisted "logic" some use to justify their near obsession with "end times events". They tell us, "True, we can't know the day or the hour, but we can know the time period" (or "age" or "season" some say). Much in the same way you ask, "can we know the year, or decade, or century?"
Intentionally or no, you have exposed the absolute folly of trying to determine if we live in the "end times" by following and piecing together current events. First, to do so, justifying such endeavors with the "logic" above, obviously twists or perverts the Scripture in question. But this isn't very surprising for anyone who comes from a "dispensational" eschatology, after all, to such people, Scripture is something to be parsed ala "Clinton", that is, it's to be "rightly divided". Funny how they are the ones who know how to rightly "divide" Scripture, like they are the real Pope or something. (Who knows how other non Catholic Christians justify their obsession, if they have one)
Secondly, and perhaps more importantly, as was correctly pointed out upthread, since the Ascension of our Lord, we have been living in the "end times", and indeed, many of the so called "signs" that are given so that we "may know" this have not only come to pass, but repeatedly so throughout history since His Ascension, such as "the sun turning black as sack cloth" (eclipses) and the "moon turning red as blood" ( lunar eclipses) and " wars and rumors of wars" and "famine".
These all, when taken together, can and DO let us know we are in the "end times", but when He returns it is not our place to know, AT ALL, or else the passage above truly has no meaning, unless (again) one is some kind of dispy-ite who has no problem parsing and carving up Scripture like some kind of pig roast, in order to sell books, ala Jack van Impe or Hal Lindsey.
