What significant dates from fiction have we reached?

This question is inspired by two things:

1. @carsonc’s comment in the hard sci-fi topic about Kim Stanley Robinson’s Red Mars starting off in 2026 (which is right around the corner).

2. I started reading Ministry for the Future (coincidentally also by Kim Stanley Robinson) for the Tildes Book Club, and the titular organization starts in, of all times, January 2025 (as in, right now! The book was a perfect pick for this month).

It got me thinking about how a lot of science and speculative fiction books from the past imagined a future ahead of themselves, and how the passage of time has brought us to or even past those imagined futures.

So I’m interested in specific date milestones from fiction that we have met or passed already. They do not have to specifically be from science/speculative fiction, though I imagine most will be.
