Today we celebrate the day of Saint Isidore, the patron saint of the Internet.

Saint Isidore's Day is celebrated on April 4th in honor of the well-known 404 error, which indicates difficulty accessing a web page.

Saint Isidore of Seville (c. 560 – April 4, 636) is known for his love of learning.

Many historians call him the most educated man of his time. For this reason, Saint Isidore is considered the patron saint of scholars and students, and since 2003, by decree of Pope John Paul II, Saint Isidore has been officially named the patron saint of computer and internet users. This decision was made because the World Wide Web is a vast treasure trove of practical and theoretical human knowledge.
