It's common for folks to add an "event" to one's calendar saying that something is due at a particular date and time.
Calendar apps call everything they store an "event."
But it feels there should be a difference between a "due date" and an event that is "something that happens" or "an activity you want to attend."
One could argue that the due date (or due datetime) is "the instant in time in which something becomes past due" so the transition from not-due-yet to past-due is a kind of event (happening in time) but this feels like a stretch.
Or is it not? Is it just me? Is a due-date in a calendar really an "event"? Or is there a word in English that exactly describes the pseudo-event of the form "I just put this due date in my calendar so I get a reminder"?
An example of a "due date" added to a calendar might be a bill that needs to be paid or an assignment to turn in. No one to meet, no one to call, no place to be, just a task to complete. So when asking "what is on your calendar?" the response of "I have three events, an appointment, a meeting, and my application is due." Here "event," I think, is better replaced with "calendar item" or just elided. An alternative is "I have two events and a target date" but I was wondering if there was an effective synonym for "target date."
