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.
If the streets on the grid were rigorously north-south and east–west, then both sunrise and sunset would be aligned on the days of the vernal and autumnal equinoxes (which occur around March 20 and September 23 respectively). In Baltimore, for instance, sunrise aligns on March 25 and September 18 and sunset on March 12 and September 29. [21]
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 sec

The sunrise equation or sunset equation can be used to derive the time of sunrise or sunset for any solar declination and latitude in terms of local solar time when sunrise and sunset actually occur. Formulation

Above 66.56° latitude, there is no sunset at all, a phenomenon referred to as the midnight sun. Solstice day arcs as viewed from 70° latitude. At local noon the winter Sun culminates at −3.44°, and the summer Sun at 43.44°. Said another way, during the winter the Sun does not rise above the horizon, it is the polar night. There will be ...
