Summary: launch windows depend on the sun

The only real restriction on the time you can launch a
geostationary satellite has to do with sun-angle restrictions on
the 
spacecraft.  You generally want the sun to be perpendicular to the solar
arrays during the coast and maneuver phases, and you don't want the
satellite tencounter long eclipses during this time.
