Don't worry, it's Friday the 13th

SPAIN Yes, today's Friday the 13th!! But we have news for you. We are in Spain, right? And in Spain the equivalent to Friday the 13th is martes 13, that is, Tuesday the 13th. So we have nothing to worry about at all. In fact, if you're really clever, you can get away with not worrying about martes 13, either, just by saying you're not Spanish. The same applies to April Fool's, Mother's and Father's Days and all sorts. Prospero's been doing it for years...
