World Book Day is celebrated on April 23 every year.

Why ” World Book Day” on April 23?:

For the simple reason of the death of three of the world’s greatest writers on that date: Inca Garcilaso de la Vega, William Shakespeare and Miguel de Cervantes.
In some countries like Cuba this day is a celebration of Language.
In some countries, for example, Spain, Argentina, and Mexico, there are activities dedicated to World Book Day. For example, in Spain they have the Book Fair,where book sellers put stalls in the streets,selling new and some used book and doing a discount.

In other places, couples give gifts. The woman gives the man a book, and the man gives a rose to the woman.
However, although the World Book Day is celebrated on April 23, we must remember that some countries either do not celebrate, or celebrate the day on a different date. For example, in Ireland and the UK they celebrate “World Book Day” every year on the first Tuesday in March.
