The sun, seems to move each day throughout the year. The proble is that the earth is moving, so it depends exactly where you are standing, as to where it will seme to rise and fall each day

If you are in the US use the first link below,

As the earth rotates, the sun appears to sweep across the sky from east to west, and the path it follows changes from season to season. In the northern hemisphere the sun rises at its most southerly point in midwinter - this is known as the winter solstice (December 21st) - and in mid-summer at its most northerly - the summer solstice (June 21st). Midway between those dates the sun rises due east and sets due west on the spring equinox (March 21st) and the autumn equinox (September 23rd). On those dates the sun rises at 6 a.m. and sets at 6 p.m. all over the world - the word "equinox" is from the Latin meaning "equal night".

The point of the heavens directly above the observer is known as the zenith, and a line drawn due south from this point to the horizon is known as the observer's meridian. The sun crosses the meridian at noon - at this point it is at its highest in the sky. The time before noon is known as ante meridian (a.m.) and after noon is known as post meridian (p.m.).

Ok, so thats the basics, but the angle on the compass at which the sun is seen to rise is known as the azimuth of the rising sun. Due north on the compass is represented by 0°, east is 90° and west is 270°. On either equinox the sun will rise at 90° and set at 270°; on the equator on that day the noon-day sun will be seen to be directly overhead (on the zenith).

The Tropic of Cancer is a line at latitude 23½°N, and represents the northernmost point at which the sun may be seen on the zenith at noon (on the summer solstice). Similarily the Tropic of Capricorn (23½°S) is the southernmost point at which the winter solstice noon sun will be directly overhead.

On the Arctic Circle (66°N) at the winter solstice, the sun does not rise above the horizon, while at the summer solstice it is seen not to set. The opposite is true for the Antarctic Circle (66°S). North or south of these latitudes there will be longer periods of the year with perpetual night or perpetual day.

The prediction of the time of sunrise and sunset would be straight-forward but for the existence of Time Zones: these are areas of the world which have agreed to a Standard Time which (mostly) differs from Greenwich Mean Time (GMT) by an integral number of hours. By definition a time zone is an area one hour "wide" (15° longitude) within which all clocks will show the same time. Therefore, by the clock, the sun will rise one hour earlier at the eastern edge of a time zone than it will at the western edge.
The way to resolve this problem is to deal with two "types" of time:
Apparent Time and Clock Time.

On the equinox, the sun rises at 6 a.m. Apparent Time; the sun on any day is at its highest in the sky at noon Apparent Time. Clock Time can be very different: for example during the summer Britain (in common with many other countries around the world) shifts its clocks forward by one hour - so-called Daylight Saving Hours - so the sun will be at its highest at 1pm Clock Time. As another example, Iceland by choice sets its clocks to GMT, but Reykjavik is a full 22° west of Greenwich - so the sun rises on the equinox at 6:00am Apparent Time, 7:28am Clock Time.

Countries nearer the equator have no requirement for Daylight Saving Hours: their hours of daylight hardly change through the year. Countries that do change their clocks in summer do so on different dates: be warned!
Check for your Daylight Saving Hours at the second link

and the third link is a sunrise/sunset reconer, for anywhere on the planet.

The East.

This is why Japan (Which is very east) is called 'the land of the rising sun'
