longitude: Definition and Much More from Answers.com (3503 words)
Longitude is given as an angular measurement ranging from 0° at the Prime Meridian to +180° eastward and −180° westward.
Ecliptic longitude is measured from 0° to 360° eastward (the direction that the Sun appears to move relative to the stars) along the ecliptic from the vernal equinox.
Ecliptic longitude relative to a moving equinox is used whenever the positions of the Sun, Moon, planets, or stars at dates other than that of a fixed equinox is important, as in calendars, astrology, or celestial mechanics.
