Time laid out so that days can be pointed at. A calendar makes duration addressable.

A named day, by which an event can be placed in time. A date is what makes a claim checkable against a record.

Something that happened, held as a discrete thing. A moment given edges so it can be recorded and pointed at.

Of the day-count calendar astronomers keep — days numbered in one unbroken line since antiquity, no months in the way.

A plan laid against time. A schedule is an intention with hours attached.

Events laid along time's own axis, ordered as they happened. The record's spatial form — history you can walk.
