Thanks! It seems, though, that this is a very new function, Aquamacs' Org-mode
doesn't contain it... I guess I'll have to find out how to update the Org-mode

Is it still possible to schedule the time of the event as well?

(I'm a bit surprised, though, that the format is `Month Day Year', when normally
