On the orientation of sunrise and sunset. Why is the global sunrise due east and sunset due west at the vernal equinox and autumnal equinox, and the sunrise due east in summer, northeast and northwest, and winter? Because the earth always turns from west to east, the sun always rises in the east and sets in the west.

In summer in the northern hemisphere, the sun shines directly on the hemisphere. For all parts of the world, the sun shines from the north, so the sun rises in the northeast and sets in the northwest.

Similarly, in winter in the northern hemisphere, the sun shines directly in the southern hemisphere, and the sun shines from the south, so the sun rises in the southeast and sets in the southwest.

At the spring and autumn equinox, the sun shines directly at the equator, so the sun shines from the east, so it rises and sets in the west.
