Calculate the sunset time, which is the solar noon time plus the sunset hour angle in degree divided by 15; Use the sunset time as input to the solar geometry routine to get the solar azimuth angle at sunset. An interesting feature in the figure on the right is apparent hemispheric symmetry in regions where daily sunrise and sunset actually occur.
The western Northern Cape and Western Cape differ, however. Everywhere on land west of 22°30′ E effectively experiences year-round daylight saving time because of its location in true UTC+01:00 but still being in South African Standard Time. Sunrise and sunset are thus relatively late in Cape Town, compared to the rest of the country.
The exception is the Western Cape and its capital city Cape Town where the climate is Mediterranean and it rains more in the wintertime. [4] In the winter months, snow collects on the high mountains of the Cape and the Drakensberg. A few times in South Africa's history snow has fallen in other regions - (provinces) such as in September 2021. [5]
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 }}}
The times of sunset and sunrise vary with the observer's location (longitude and latitude), so the dates when day and night are equal also depend upon the observer's location. A third correction for the visual observation of a sunrise (or sunset) is the angle between the apparent horizon as seen by an observer and the geometric (or sensible ...

Scarborough is a seaside town situated within the City of Cape Town on the Cape Peninsula in the Western Cape province of South Africa, situated at the edge of the Cape Point Nature Reserve. [2] The town's boundary includes Scarborough Beach, which is popular with surfers. [3] This town was designated as a conservation village in April 1996 ...
Many ancient monuments in Europe especially, as well as parts of the Middle East, Asia and the Americas, are aligned with the sunrise or sunset on the summer solstice (see archaeoastronomy). [ 9 ] [ 10 ] The significance of the summer solstice has varied among cultures, but most recognize the event in some way with holidays , festivals , and ...
