If you’re really into moonwatching and want to participate in an extremely interesting global project, visit the Islamic Crescents’ Observation Project (ICOP)’s Web site. The project was organized by the Arab Union for Astronomy and Space Sciences and the Jordanian Astronomical Society. It aims to gather information about the visibility of new moons at the start of each lunar month. Anyone can participate, regardless of his/her location, nationality, or religion. |

The U.S. Naval Observatory offers the most reliable information on what the moon is doing astronomically, which isn’t always visible. Their essay on “Crescent Moon Visibility and the Islamic Calendar” explains the challenges inherent in trying to actually see the first thin crescent of the new moon. At the end of the essay are three links to USNO’s information on the moon and its phases. |

If you’re more interested in the Islamic calendar than in moonwatching, this attractive Web site offers clear explanations in an easy-to-read format. |
