    As a result of the Earth's orbit around the Sun, the Sun's latitude position appears to move seasonally between the Tropic of Cancer and the Tropic of Capricorn.. Places on Earth experience the apparent diurnal motion of the Sun from the east to the west, during which it culminates, or reaches its highest point of the day and crosses the local meridian.

    Likewise, the earliest sunset does not occur on the winter solstice, but rather about two weeks earlier, again depending on the viewer's latitude. In the Northern Hemisphere, it occurs in early December or late November (influenced by the Earth's faster movement near its perihelion, which occurs around January 3). [citation needed]
