Children throughout the area have spent the day in nurseries and schools dressed as their favourite book characters.
From Peter Rabbit to characters from Willy Wonka, children have used their imaginations to bring the characters off the pages of books and in to life.
World Book Day has become a popular inspiration to get youngsters interested in reading, through dressing up for a day.
Here we have just a few on our special video.
And it’s not too late to take part in our special feature and send in your photographs of your children or classmates dressed up for World Book Day. Send to: firstname.lastname@example.org
