Halcon:
It's no longer a year tying to the present (the old pre-1995 generation belief). Realistically, that's the only reason why it mattered.
Indeed, 1914 is itself tied to their past, which some people imagine to be less relevant for JWs because it is so long ago (often in relation to the very broken teaching about the 'generation'). But their beliefs about 1914 underpin their supposed claim of authority. To abandon their '1914' doctrine, they also need to reinvent their 'faithful slave' teaching as the basis for the 'Governing Body' or the Watch Tower Society or Jehovah's Witnesses having any 'divine backing'.
