I did a World Book Day event yesterday, at the Cambridge International School just down the road from me. If you are reading this outside of the UK and Ireland you will be confused. We decided against having World Book Day on April 23 when everyone else celebrates it, despite it being a UNESCO idea. I'm not really sure we have much of a claim to calling it World Book Day, but it is such a good cause that no one ever seems to complain. It does miss the point of the whole world joining in, though. The reasons seem to revolve around the idea that schools may be closed because of the shifting nature of the Easter school holidays and the fact that it is St George's Day.
I'm not sure why St George's Day is incompatible with World Book Day and April 23 is also cited as the anniversary of the death of William Shakespeare, which seems to make the day more suitable, not less.
Anyway, my World Book Day event was fun. I arrived to watch teachers in costume recommend books to their students, who were also in costume - and that is rare in a secondary school. We had some readings and even a little acting, and then I had eight minutes or so to sum up my career, explain the plot of my latest book, do a reading and take questions from the audience. It was all a bit of a blur and then I was back in the car and back home.
