La Diada de Sant Jordi, also known as el dia de la rosa (The Day of the Rose) or el dia del llibre (The Day of the Book) is a Catalan holiday celebrated on April 23 as lovers day with some unique twists that show the ancient practice of this day. The main event is the exchange of gifts between sweethearts, loved ones and respected ones. Historically, men gave their girlfriends and wives roses, and women gave their boyfriends and husbands a book to celebrate the occasion. In modern times, the mutual exchange of books is quite often. Roses have been associated with this day since medieval times. Barcelona is an important publishing capital in both Catalan and Spanish.
