The following is a list of cities by sunshine duration.Sunshine duration is a climatological indicator, measuring duration of sunshine in given period (usually, a day or a year) for a given location on Earth, typically expressed as an averaged value over several years.
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 sunniest month in the world is December in Eastern Antarctica, with almost 23 hours of bright sun daily. [ 7 ] Conversely, higher latitudes (above 50° north/south) lying in stormy westerlies have much cloudier and more unstable and rainy weather, and often have the lowest values of sunshine duration annually.
Sunsets are an hour earlier after daylight saving time ended Sunday. Here are sunrise and sunset times for the next 10 days in Kansas City.

The slight effect of daylight hours on average seasonal temperature can be seen with the poles and tropical regions. The poles are still cold during their respective summers, despite seeing 24 hours of daylight for six months, while the Equator remains warm throughout the year, with only 12 hours of daylight per day.
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
All-time record lows are spread across December, January or February for many cities: Boston, New York City's Central Park and Philadelphia all set their records in a Feb. 9, 1934, cold outbreak ...
