This year, World Book Day is on Thursday 4 March. In the UK, it is always held on the first Thursday in March.

The main focus of the event is the £1 book tokens that are distributed by schools and nurseries and can be redeemed against the World Book Day £1 books or against full-price books or audiobooks that cost £2.99 or more. Tokens can be used in most major bookshops and supermarkets and are valid from Thursday 27 February until Sunday 29 March 2020.

This year, World Book Day is also running a Share A Million Stories campaign to promote 'story-sharing': a child “being read to or reading with an adult, sibling, friend – or pet – for a minimum of 10 minutes” at school and home. Find out more and register your interest on the World Book Day website.

World Book Day was originally created by UNESCO, and has been celebrated since April 1995. The premise is to celebrate and encourage reading but has become primarily known as a day to dress children up as book characters. See below for parent-approved resources on pulling together a World Book Day costume without the fuss.
