Time is a magnitude of physics directly related to the exact sequencing of occurrences of natural events. It is established following spatial and temporal coincidences between such events, as well as observing clocks synchronized and linked with the origin and the coordinated axes of the reference for which time is defined.
Due to the Earth's rotation on its axis, in the morning the sun rises to the east and hides to the west on the horizon. On the following day, the same cycle is repeated, and on the following ones, the same sequence continues, thus showing a pattern that can be observed and used to count the days.
