Only from an outside perspective. Inside the black hole it’s already next Tuesday.
Comment on How would one exit a black hole?

With the assumption that we are alright in there, wait until it evaporates naturally. I hope you brought a lot of books, cause depending on its mass, it can take some time.

Actually, it may be that it quite literally can’t take any time inside a singularity! As you approach a singularity, the spacetime curve representing the passage of time approaches zero, meaning that from your perspective, the universe outside the event horizon moves more and more impossibly fast, and from an outside perspective, you move more and more slowly until your motion appears to stop entirely.
At the singularity, our understanding of spacetime basically just shrugs in an infinite manner, puts on its hat, and clocks out for the day. It may be that, for the singularity, the entirety of time between the collapse of the star that formed the black hole and the eventual evaporation of the black hole due to Hawking radiation are compressed into a single instant, and no time at all passes for it.
So you might not need any books at all, because by the time you reach the singularity (which wouldn’t take a particularly long subjective time), it may well be the end of the universe. Hope you paid the meter.
