World Book Day - this year marking its 20th anniversary - is an annual celebration of authors, illustrators and books marked by more than 100 countries around the world.
It is a chance for schools and parents to encourage children - and teachers - to dress as their favourite characters, receive book tokens and take part in events.
Parents and schools from around the region have been sending us pictures of their day - including one from Beeston Hall School of author Julian Segwick knife juggling during a visit.
The school also welcomed author Vivian French to talk to children from six different schools in the area.
