The above relation implies that on the same day, the lengths of daytime from sunrise to sunset at and sum to 24 hours if =, and this also applies to regions where polar days and polar nights occur. This further suggests that the global average of length of daytime on any given day is 12 hours without considering the effect of atmospheric ...
The following tables contain information on the length of the day on 20 June 2016, close to the summer solstice of the Northern Hemisphere and winter solstice of the Southern Hemisphere. The data was collected from the website of the Finnish Meteorological Institute [ 7 ] as well as from certain other websites.
If the birth occurred before sunrise, find the time of sunset on the previous day. Find the duration of the time between that previous day's sunset and this day's sunrise. This duration is called ratrimÄna. If the birth occurred after sunrise, during daytime (before sunset), find the time of sunrise the same day.
It is also hard to detect the changes in sunrise/sunset azimuth due to the atmospheric refraction [27] changes. Those accuracy issues render it impossible to determine the solstice day based on observations made within the 3 (or even 5) days surrounding the solstice without the use of more complex tools.
In sunrise/sunset tables, the atmospheric refraction is assumed to be 34 arcminutes, and the assumed semidiameter (apparent radius) of the Sun is 16 arcminutes. (The apparent radius varies slightly depending on time of year, slightly larger at perihelion in January than aphelion in July, but the difference is comparatively small.) Their ...
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.

A good example would be Brown's, which commenced in 1877, and is still produced annually, its early 20th-century subtitle being "Harbour and Dock Guide and Advertiser and Daily Tide Tables". This combination of trade advertising, and information "by permission... of the Hydrographic Department of the Admiralty " provided a useful compendium of ...
