In June or December, astronomical dawn to sunrise or sunset to astronomical dusk occurs at latitudes less than 48°34' North or South, because in June the Sun crosses the Tropic of Cancer (about 23°26' North) and in December the Sun crosses the Tropic of Capricorn (about 23°26' South).
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 ...
The December-solstice solar year is the solar year based on the December solstice. It is thus the length of time between adjacent December solstices. The length of the December-solstice year has been relatively stable between 6000 BC and AD 2000, in the range of 49 minutes 30 seconds to 50 minutes in excess of 365 days 5 hours.

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.
Sun path, sometimes also called day arc, refers to the daily (sunrise to sunset) and seasonal arc-like path that the Sun appears to follow across the sky as the Earth rotates and orbits the Sun. The Sun's path affects the length of daytime experienced and amount of daylight received along a certain latitude during a given season.
Autumn in Paris. Paris has a typical oceanic climate (Köppen climate classification: Cfb), affected by the North Atlantic Current. The overall climate throughout the year is mild and moderately wet. [1] Summer days are usually warm and pleasant with average temperatures between 15 and 25 °C (59 and 77 °F), and a fair amount of sunshine. [2]
A plot of hours of daylight as a function of the date for changing latitudes. This plot was created using the simple sunrise equation, approximating the sun as a single point and does not take into account effects caused by the atmosphere or the diameter of the sun.
