I got the impression Finn had been unconscious in the giant ziploc Bacta fluid bag for a few weeks at least.
As with the timelines in every Star Wars movie, it’s entirely ambiguous (and ultimately unimportant).
Also
My point is that those saying a Jedi’s powers come from achieving a certain state of mind (with which I agree) have to accept that Rey has achieved at least enough “zen” to become as powerful as any Jedi to come before her, all in about a week. She may not be enlightened yet, but she’s apparently achieved enough focus and determination in a few days that her powers are only lacking in comparison to previous Jedi by mere degrees; a bit of finesse is all that truly separates her from the greats who came before.
To be clear I’m not saying that. What I’m saying is a Jedi’s powers are not what defines their mastery, or at least in in my opinion shouldn’t be. (To make a literal comparison, Anakin is implied to be possibly the most powerful Jedi in the order during ROTS, but he is not granted the rank of master.)
Whatever power in the force Rey has demonstrated is far less important to her status as a strong Jedi than factors like wisdom, knowledge, and discipline. Despite the raw strength she’s exhibited, her technique is never anything but messy. Her hard work and determination lets her be especially in tune with the force, but she doesn’t have the command of it yet that a Jedi would. She may have the spirit of a true Jedi, but she (again) is not a Jedi yet. She’s got some growing to do.
All of this is beside the fact that anyone who says TLJ makes Rey out to be the “best and most powerfulest Jedi ever” is completely ignoring the fact that the film goes out of its way to give the most impressive and impactful bit of force usage in the entire series to not Rey, but Luke… and then goes on to imply that he will live on as potentially the most legendary and inspirational Jedi ever. But Rey lifted some rocks though so they’re forcing her seem like she’s the bestest.
