The Full Moon
Full moon is a lunar phase that occurs when the Moon is on the opposite side of the Earth from the Sun. More precisely, a full moon occurs when the geocentric apparent longitudes of the Sun and Moon differ by 180 degrees; the Moon is then in opposition with the Sun.[1] At this time, as seen by viewers on Earth, the hemisphere of the Moon that is facing the earth (the near side) is fully illuminated by the Sun and appears round. Only during a full moon is the opposite hemisphere of the Moon, which is not visible from Earth (the far side), completely unilluminated.
As a lunar month is about 29.531 days long, the full moon falls on either the 14th or 15th of the lunar month in those calendars that start the month on the new moon. In any event, the period between full moons can be either 29 or 30 days.

Bomba's Full Moon Party
In the middle ages it was a common belief that the full moon caused people to behave strangely . Infact, the word "lunacy" meaning "insanity" comes from the Latin word for "moon." Of course that's absolute nonsense...or is it? Find out by attending the biggest party in the BVI held every month at Bomba Shack in Capoons Bay, Tortola.
The music will be blasting and drinks will be flowing all night, including Bomba's infamous Bomba Punch and Mushroom Tea.
Sailors wishing to attend the Full Moon Party can anchor at Cane Garden Bay or Soper's Hole where there will be plenty of taxis available to ferry you to the fun.
Bomba follows The Old Farmer's Almanac schedule of moon cycles to plan his party each month. You can find the dates here.
