This vCalendar moon events file contains moon phase events (New Moon, First Quarter Moon, Full Moon, and Last Quarter Moon) from January 1, 2002 through December 31, 2015. Many calendar applications can use the information in this file directly or through an import mechanism.

Follow these installation instructions to populate a Microsoft Outlook calendar with moon phase information (and thus know when full and new moons occur):

1. Download the moon events file
2. Start Outlook
3. Select File / Import and Export
4. Choose "Import an iCalendar or vCalendar file (.vcs)"
5. Find the MoonEvents.vcs file that you saved; highlight it and click "OK"

Visit the U.S. Naval Observatory Astronomical Applications Department for additional astronomical data; here is information on vCalendar.

Enjoy! Please share installation instructions for other calendar applications.
