nit-pick: no comma before the "and" (because an Oxford comma is only used for lists with at least 3 items AFAIK).
nit-pick: I would put this line in a separate paragraph so that it stands out. And maybe even make it also bold.

Not 100% correct. They will be shows for some days since we don't want to clutter the front page with "old" blog posts. If people are interested in all posts they should use an RSS reader.
Wrong: date always needs to be there. publishDate can (and should) be omitted on articles.
I don't see a use case for a separate publish date on blog posts. We can still schedule them by using the date field, but why should there be a different publication date from the date that's…
Not 100% correct, they will also be shown up to 6 hours after the date so that events that are currently running are still present on the home page.
Events should also have a publishDate since the post should usually be published before the event is happening.
Soll das ein Artikel oder Event sein? Weil Artikel mit Location nicht offiziell supported sind!
