This page graphically displays sunrise and sunset times for a given location for an entire year.

- On the ‘Day Length’ tab, each vertical line of pixels corresponds to one day, with the display covering one year. The left hand side of the display is six months in the past, the right hand is six months in the future, and the center of couse is today. The vertical range of the display covers the 24 hours of the day, with the pale blue section being daytime, and the constellations nighttime.
- To see what the year is like from another location, go the the ‘My Location’ tab and click anywhere on the world map, or on one of the buttons naming the world’s five most important cities. (You’ll see that Melbourne is pre-selected). Go back to the ‘Day Length’ tab to see the year’s day lengths being recalculated.
