>Yoshida's knowledge of the prophecy is given to him by the Death Devil
This is wrong. In chapter 122 he brings up nostradamus' prophecy to her, specifically saying the KoT will descend. In ch 146, barem likewise says the KoT. In both 191 and 194, Yoshida says the death devil is coming in a month, not the KoT. The given dates are tied to different "actors Nostradamus expected and who they actually are," as you put it.

We've had multiple examples already of the prophecy being fallible or characters being flat-out wrong about prophecy-related shit:
>shiga says she altered the prophecy
>yoshida thinks the death devil is coming when she's already here
>In response to Barem's pronouncement in ch. 146, Nayuta says "Fami and I, we can tell. Cuz we're sisters. The great king of terror is probably coming for real. We know it cuz she's our eldest sister... the death devil". Characters in this manga sometimes speak out of their asses with confidence, just like real people do.

>Fujimoto made a mistake with his timeline, that is the most sensible explanation to me.
That's far more likely than a mid-194 timeskip, but again, the manga isn't over and there is absolutely ZERO chance things don't go sideways from what we expect.
