### Hours

"Midnight (or noon) ~ above a 12-hour analog clock one hour is a unit the time conventionally reckoned as 1⁄24 that a day and scientifically reckoned as 3,599–3,601 seconds, relying on conditions.The seasonal, temporal, or unequal hour was established in the ancient Near eastern as 1⁄12 that the night or daytime. Such hrs varied by season, latitude, and weather. It to be subsequently separated into 60 minutes, each of 60 seconds. That is East oriental equivalent to be the shi, which to be 1⁄12 that the evident solar day; a similar system to be eventually occurred in Europe which measured its same or equinoctial hour as 1⁄24 of together days measured from noon to noon. The minor variations of this unit were eventually smoothed by making the 1⁄24 of the median solar day, based upon the measure up of the suns transit along the celestial equator rather than follow me the ecliptic. This was finally abandoned as result of the boy slowing led to by the Earths tidal deceleration by the Moon.In the modern metric system, hrs are an welcomed unit that time same to 3,600 seconds yet an hour the Coordinated universal Time (UTC) may incorporate a confident or negative leap second, make it critical 3,599 or 3,601 seconds, in order to store it in ~ 0.9 secs of universal time, which is based upon measurements of the mean solar day at 0° longitude."
