There are a lot of reasons why we still look at the moon. Some of us (like myself) do night photography. Religions and astrologers ascribe meanings to the moon. Still other people haven't quite gotten over watching the Teen Wolf series of movies and only shave every new moon.
30boxes is a wonderful AJAX calendar service. There already is the ability to see the next week's weather, which is great for planning my night photography. So I decided to write a calculator to figure the phase of the moon and export it as an RSS feed that 30boxes can add to one's calendar.
Simply add http://www.wirewd.com/calc/lunar.cgi as a syndicated web feed and you can track the phase of the moon throughout the month
