East is the direction in which the Earth rotates about its axis. Therefore it is the direction from which the sun rises at the equinox. Another consequence is that it is the preferred direction of space launches, because of the saving of delta-v.
"The East" also often refers to Eastern countries. When used in this sense, it could, depending on context, refer to the Middle East, Eastern Europe, South Asia, Southeast Asia, East Asia, or even all of Asia. See also: Eastern, Eastern philosophy, Near East, Far East, Levant, Orient
