World Book Day will mark 30 years of literary fun in 2025.
Unesco, which promotes global education, culture and heritage, created the annual event on April 23, 1995. Since then, it has become a worldwide movement celebrating books and encouraging children to read.
Some experts say the biggest indicator of a child’s future success is whether they read for pleasure. They say this matters more than family circumstances, parents’ income, or educational background.
So how can you and your little bookworms celebrate World Book Day 2025?
Here’s all you need to know.
