It’s a fools errand to date set, which I never advocate. We’re to know the season - and I think we’re in that season. Whether it’s days, years, or decades (highly unlikely) is anybody’s guess.
Personally, I believe that we could very well be in the season leading up to the one, definitive Second Coming of the Lord. To me, the big indication is the obvious indicator is that we are experiencing a Great Apostasy that, at this point, shows no sign of reversing. When the Jews start converting to Christ en masse, we are off to the races.
