Daylight Tracker

This applet is a port to Java of the 'night & day' algorithm from XsunClock, by John Walker. The port was performed by André-John Mas. The source code is available upon request - my e-mail address is available on my web page.

Compatibity issues: If you see a grey box, then you are probably running Windows without Java installed, or Microsoft's implementation of Java, which is not up to date. If you need to install Java, then click on the Java logo below. Details for other operating systems is also covered by the link:
