IANAJ but I've been curious about Middle East religions.

> So that they can go to hell instead of the jew, or whatever?

Anyone who follows https://en.m.wikipedia.org/wiki/Seven_Laws_of_Noah is an OK chap apparently, probably not as cool as a Jew but I guess not to burn either? Shabbath stuff is only important if you are a Jew.

> meaning that you can take the elevator on a Shabbat

If you are really strict and not disabled you would not use elevator even with this workaround.

> I was under the impression that Shabbat was on a Friday or Saturday

Outside of Israel some places switched to Sunday because otherwise too few people care.
