Earth-based: the day is based on the time it takes for the Earth to rotate on its own axis, as observed on a sundial [citation needed]. Units originally derived from this base include the week (seven days), and the fortnight (14 days). Subdivisions of the day include the hour (1/24 of a day), which is further subdivided into minutes and seconds ...

A timeline is a list of events displayed in chronological order. [1] It is typically a graphic design showing a long bar labelled with dates paralleling it, and usually contemporaneous events.
