Day vs. Date

By Jaxson

  • Day

    A day, a unit of time, is approximately the period of time during which the Earth completes one rotation with respect to the Sun (solar day). In 1960, the second was redefined in terms of the orbital motion of the Earth in year 1900, and was designated the SI base unit of time. The unit of measurement “day”, was redefined as 86 400 SI seconds and symbolized d. In 1967, the second and so the day were redefined by atomic electron transition. A civil day is usually 86 400 seconds, plus or minus a possible leap second in Coordinated Universal Time (UTC), and occasionally plus or minus an hour in those locations that change from or to daylight saving time.

    Day can be defined as each of the twenty-four-hour periods, reckoned from one midnight to the next, into which a week, month, or year is divided, and corresponding to a rotation of the earth on its axis. However its use depends on its context, for example when people say ‘day and night’, ‘day’ will have a different meaning. It will mean the interval of light between two successive nights; the time between sunrise and sunset. People tend to sleep during the night and are awake at a day, in this instance ‘day’ will mean time of light between one night and the next.However, in order to be clear when using ‘day’ in that sense, “daytime” should be used distinguish it from “day” referring to a 24-hour period ; this is since daytime typically always means ‘the time of the day between sunrise and sunset. The word day may also refer to a day of the week or to a calendar date, as in answer to the question, “On which day?” The life patterns (circadian rhythms) of humans and many other species are related to Earth’s solar day and the day-night cycle.
