Try this:
function getAngle(from, to){
function wrapAngle(angle){
if (angle>=360) {
angle-=360;
} else if (angle<0){
angle+=360;
}
return angle;
}
var DEGREE_PER_RADIAN=57.2957795, RADIAN_PER_DEGREE=0.017453;
var dLat=to.lat()-from.lat(), dLng=to.lng()-from.lng();
var yaw=Math.atan2(dLng*Math.cos(to.lat()*RADIAN_PER_DEGREE),
dLat)*DEGREE_PER_RADIAN;
return wrapAngle(yaw);
}
'from' and 'to' are both LatLng objects.
