Days
Days (pronunciation: /deɪz/) are a unit of time, typically representing 24 hours. The term originates from the Old English dæg, which is related to similar words in many other Germanic languages.
Definition
A day is a unit of time. In common usage, it is either an interval equal to 24 hours or daytime, the consecutive period of time during which the Sun is above the horizon. The period of time during which the Earth completes one rotation with respect to the Sun is called a solar day.
Etymology
The word "day" originates from the Old English word dæg, with its cognates such as dagur in Icelandic, Tag in German, and dag in Dutch. These are all descended from the Proto-Germanic *dagaz.
