Nychthemeron
From Wikipedia, the free encyclopedia
Nychthemeron or nycthemeron or nuchthemeron (from Greek nykt- "night", (h)emera "day") is a period of 24 consecutive hours. It is sometimes used, especially in technical literature, to avoid the ambiguity inherent in the term day.
It is the period of time that a calendar normally labels with a date.
[edit] In other languages
The word døgn in Danish and Norwegian, or dygn in Swedish, can mean 24 hours, or more loosely a day plus a night in no particular order. Unlike a calendar date, only the length is defined, with no particular start or end. The word is basic and essential in these languages, and unlike "nychthemeron", is not associated with jargon.
