sunset position prediction

Is there a site that will tell me the exact heading to which the sun will set for a given day and location? Obviously the sun sets in the west, but as the seasons change it sets in different locations, I need to figure out exactly where...

Plenty of websites will tell me at what time the sun rises and sets, but what I need is exact heading.

Thanks in advance hive-mind!!

Wunderground does it. Enter your city, then find the button labelled "extended view" underneath the astronomy data. It'll give you locations for rise, set, and noon.

This calculator (from includes azimuth and altitude information for a specific date and time (relative to a position you provide).

Response by poster: Thanks everybody, when I actually did a bit more googling, I found this site which works just fine.

This sunrise and sunset calculator also does it--after choosing your city, choose the "rise/set time/azimuth" from the "Columns" pull-down menu.
