|Knowing the sunrise and sunset time maybe important information for applications that depend on whether it is day or night.
The sunset or sunrise time information may useful for something like giving the appropriate salute to an user given the current time of the day, or other more complex situations that depend on knowing whether it is day or night where an user lives.
The calculation of the sunrise and sunset is not trivial. It depends on the geographic coordinates of the place in the world being considered, the day of the year and the position criteria that determines exactly when it is considered to start the sunrise or sunset.
This class provides a solution that simplifies that problem by making the correct calculations considered all the important factors.
