Wales1976, the TV channels won't publish their TV schedules so far in advance, as they won't want the other side pulling out all the stops to put something good on against their top shows.
The TV schedules are usually given to the TV guides about 3 weeks before broadcast, a little earlier for Christmas, though as anyone who buys The Sun for it's Christmas TV guide will know, a lot of blanks are filled in nearer to the time.
