On the last night of February and the first of March in Spain, young marceros, or March serenaders, wander through the streets singing songs to their girlfriends and asking for donations of food and sweets to celebrate the arrival of spring. The term marzas refers both to the traditional songs they sing and to the gifts they receive. Although the songs themselves vary, they always mention the month of March and the coming of spring, leading many to believe that the tradition has its roots in pagan rituals celebrating the passing of winter.
