The image above is the city of Taipei from a roof on the east side of town looking west. The location of the marks on the ring below the picture correspond to the location on the horizon where the sun sets on that day. Each black mark on the ring represents a day and the numbered and colored sections indicate the months of the year. The far left and right ends of the ring mark the solstices (winter and summer). The two black diamonds indicate the equinoxes. Notice that the equinoxes are not in the middle of the ring, but are instead are skewed a good distance to the right (north), indicating that Taipei is north of the equator.

I video taped a number of sunsets from the same location over a year. Still pictures from those videos can be seen by clicking the red marks on the ring above. The few groups of marks that are close to each other (September 28, 29 and 30) most clearly show the motion of the sun from day to day.

References: Sunrise and Sunset info for where you are at right now. The ring above is sort of an Archeoastronomical calendar, although Taipei isn't particularly ancient and probably wasn't built intentionally as a calendar. Abrams Planetarium Skywatcher's Diary is an awesome general resource for backyard astronomy. The Star Hustler, Jack Horkheimer, did a show on this very topic, so I am told. I didn't see it and was unable to find a script about it at his site, but it is a good site none the less.
