| | Day - Wikipedia, the free encyclopedia |
 | | Days such as Christmas Eve, Halloween, and the Eve of Saint Agnes are the remnants of the older pattern when holidays began the evening before. |
 | | In astronomy, the sidereal day is also used; it is about 3 minutes 56 seconds shorter than the solar day, and close to the actual rotation period of the Earth, as opposed to the Sun's apparent motion. |
 | | Present common convention is for the civil day to begin at midnight, that is 00:00, and last a full twenty-four hours until the next 00:00 (also known as 24:00, but this is not as widely used). |
