The moon will be 100% full Thursday, May 27, 2010 at 4:07 P.M. Las Vegas, Nevada time.
“American Indians gave names to each of the full moons to keep track of the passing year. The names are associated with the entire month until the next full moon occurs. Since a lunar month averages 29 days, the dates of the moons change from year to year. Here are titles most closely associated with calendar months.”
