Just when I thought I’d finally solved all the mysteries of the universe (I’m ambitious), I have discovered that there are two World Book Days.

Why?

The one I wrote about recently which took place on 3rd March was for the UK. The other one, celebrated on 23rd April, is for the whole world.

Thanks to Michael Crossland for pointing this out to me.

On the subject of special days, you might enjoy reading my article on National Introverts Week.
