PARENTS, put this date in your diary: June 21.

You have exactly five months to work out how to pamper yourself on that very special Saturday, knowing the kids will be occupied and the Playstation silenced.

Why? Because that is the publication date of the fifth Harry Potter book. And these books about wizardry have their own magic powers: they keep children spellbound.

Author JK Rowling has introduced a generation to the joy of reading. By so doing, she has guaranteed a million households a few moments of precious peace and quiet.

Perhaps we should in future designate June 21 as St JK's Day.
