The image on this page is a live simulation of the current phase of the moon, delivered as a web gadget. In addition to the image, it also shows the length of time until the next (and since the previous) new or full moon.

This gadget was featured in my second book, Pro Web Gadgets across iPhone, Android, Windows, Mac, iGoogle, and More, published in December 2009 by Apress. In the book, this gadget is used to illustrate the techniqures involved in deploying a single web gadget code base to a multitude of platforms, from pure web portals to native smartphone applications.

In addition to being a case study in the book, Moon Phase is also a fully functional web gadget, used and enjoyed by tens of thousands of people worldwide. You can be one of them; simply select your preferred platform below.

If you have any questions about the gadget or the book, please contact me.

The image on this page is the live gadget in its native form; it can be embedded into any web page in this same way. You'll simply need to insert code like this into your page's HTML source:

<iframe style="width: 300px; height: 200px;" src="http://daylightmap.com/moon/phase.html"></iframe>

Note that you can select essentially whatever width and height you like; the gadget does a pretty good job of adjusting its content to its container.
