The length of the day changes from place to place and from season to season. The table below shows the times of sunrise and sunset on a certain day in August in certain cities of the world. Latitude is the angular distance of a place north or south of the earth's equator, usually expressed in degrees and minutes. The table also shows the latitudinal positions of these cities.
