Sunset (or sundown) is the disappearance of the Sun at the end of the Sun path, below the horizon of the Earth (or any other astronomical object in the Solar System) due to its rotation. As viewed from everywhere on Earth, it is a phenomenon that happens approximately once every 24 hours, except in areas close to the poles .
The times of the rising and the setting of the upper solar limb as given in astronomical almanacs correct for this by using the more general equation cos ω ∘ = sin a − sin ϕ × sin δ cos ϕ × cos δ {\displaystyle \cos \omega _{\circ }={\dfrac {\sin a-\sin \phi \times \sin \delta }{\cos \phi \times \cos \delta }}}
It generally indicates the period of time when the sun is close to the horizon and comprises the periods of civil, nautical and astronomical twilight. The exact times when evening begins and ends are subjective and depend on location and time of year. It may be used colloquially to include the last waning daytime shortly before sunset. [2]
The Roman day starting at dawn survives today in the Spanish word siesta, literally the sixth hour of the day (sexta hora). [ 11 ] The daytime canonical hours of the Catholic Church take their names from the Roman clock: the prime , terce , sext and none occur during the first ( prīma ) = 6 am, third ( tertia ) = 9 am, sixth ( sexta ) = 12 pm ...
A clear convention may be legally defined or culturally promulgated. For example, the Hebrew calendar associates the start of a new day with sundown and midnight being a relative hour falling six hours after sundown. [6]: 25 Similarly, in traditional Arabic time at sunset, which marked the start of each new day, clocks were reset to 12:00.
Twilight occurs according to the solar elevation angle θ s, which is the position of the geometric center of the Sun relative to the horizon. There are three established and widely accepted subcategories of twilight: civil twilight (nearest the horizon), nautical twilight, and astronomical twilight (farthest from the horizon).
