Is there a direct link to bookmark that creates a new Facebook event?
The following button is associated with the URL
https://www.facebook.com/events/upcoming# and thus does not directly link to creating a new event.
No, there isn't a direct link to a standalone page to create a new Facebook event.
That "Create" button is only designed to create that overlay you would have seen, and never take you to a page where you would fill in the event details.
