The sun rises, generally, in the east, but in the northern hemisphere, particularly as you go further north, during the winter months, the sun is in the more southern part of the sky. It rises in the southeast, and even at noon, it’s not directly overhead, but is still in the southern half of the sky; it then sets in the southwest. This is most extreme at the winter solstice (December 21st or thereabouts).
As the calendar progresses from the solstice, through January and February, the sun appears to be less “southern” – its position at dawn each day is a little further north, heading towards due east, rather than southeast, and its position at sunset is also a little further towards due west.
By the time of the spring equinox (March 21st, more or less), the sun will appear to rise at due east, and sets at due west.
