Why Does the Sun "Rise" and "Set"? Exploring the Earth's Daily Cycle.

Figure 7. The daily or diurnal paths of the Sun during the solstices 21 December and 21 June and the equinoxes 21 March and 21 September as seen by an observer at the equator. Solid lines are daytime, dashed lines are night-time. At all seasons on the equator, the daily paths of the Sun are divided equally above and below the horizon. The same information shown in Figure 7 is presented in Figure 7a, below, in the form of a polar plot of the position of the Sun in the coordinates of the azimuth and altitude of the Sun as seen by an observer at that latitude.

Where Does the Sun Rise and Set? Most people know that the Sun "rises in the east and sets in the west". However, most people don't realize that is a generalization. Actually, the Sun only rises due east and sets due west on 2 days of the year -- the spring and fall equinoxes! On other days, the Sun rises either north or south of "due east" and sets north or south of "due west. At the summer solstice, the Sun rises as far to the northeast as it ever does, and sets as far to the northwest. Every day after that, the Sun rises a tiny bit further south. At the fall equinox, the Sun rises due east and sets due west. It continues on it's journey southward until, at the winter solstice, the Sun rises are far to the south as it ever does, and sets as far to the southwest. Many, if not most, prehistoric cultures tracked these rising and settings points with great detail. If they had jagged mountains along the horizon, the exact points could be readily remembered.

On other days, the Sun rises either north or south of "due east" and sets north or south of "due west. At the sun rise and set equinox, the Sun rises due east and sets due west.

Back when this calculator was first created, we decided to use a non-standard definition of longitude and time zone, to make coordinate entry less awkward. So on this page, both longitude and time zone are defined as positive to the west, instead of the international standard of positive to the east of the Prime Meridian. We maintain this page as a courtesy to those people who, for whatever reason, prefer the old calculator. Month: Day: Year e. The following sign conventions are used:. If you select a city from the pulldown menu, the latitude, longitude and time zone fields will be filled in automatically. Otherwise, the time zone associated with the selected city's Local Standard Time will be automatically entered.

In the state of Texas, you'd moving at about 1, kilometers an hour due to rotation. Or, rock cairns could be used. This is what happens on the earth as it rotates toward the east counterclockwise. Month: Day: Year e. Most people know that the Sun "rises in the east and sets in the west". And paint your car windows black so that the motion of objects relative to you don't throw you off.

On other days, the Sun rises either north or south of "due east" and sets north or south of "due west. You may wonder why you don't feel this speed: it's because human beings have no 'speed organs' which can sense absolute speed.
