"1914 + 120 years given to Noah to building ark before flood came brings us to 2034"
Blondie, twenty or so years ago, the WT discovered that link* and mentioned it. It led to speculation on here that 1934 might become a new date. It seems to have fizzled out between then and now. Obviously the new GB doesn't have the same appetite for dating shenanigans that previous iterations of leadership had.
Here is a question I asked about it and some links to that discussion back in the day. Just search for 2034 on here for more links.

* I remember reading a 1990s WT or Awake! article suggesting that Noah took fifty or so years to build the ark. I had already thought that they might give themselves some breathing space by using your above calculation. I refused to publish that idea on forums like this because I didn't want to give the Bethel monitors of such sites any ideas. In the early 2000s Bethel seems to have discovered it and ran with it.
