  1. Day

    A day is a unit of time. In common usage, it is an interval equal to 24 hours. It also can mean the consecutive period of time during which the Sun is above the horizon of a location, also known as daytime. The period of time measured from local noon to the following local noon is called a solar day. Several definitions of this universal human concept are used according to context, need and convenience. In 1967, the second was redefined in terms of the wavelength of light, and it became the SI base unit of time. The unit of measurement for time called "day", redefined in 1967 as 86,400 SI seconds and symbolized d, is not an SI unit, but it is accepted for use with SI. A civil day is usually also 86,400 seconds, plus or minus a possible leap second in Coordinated Universal Time UTC, and, in some locations, occasionally plus or minus an hour when changing from or to daylight saving time. 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?" Day also refers to the part of the day that is not night — also known as daytime. The life patterns of humans and many other species are related to Earth's solar day and the cycle of day and night.

Dictionary of Nautical Terms

  1. day

    The astronomical day is reckoned from noon to noon, continuously through the twenty-four hours, like the other days. It commences at noon, twelve hours after the civil day, which itself begins twelve hours after the nautical day, so that the noon of the civil day, the beginning of the astronomical day, and the end of the nautical day, occur at the same moment. (See the words SOLAR and SIDEREAL.)
