Today's Spanish Word of the Day was "cuarto" as in fourth: cuarto, adjective,

Espaņa ocupa el cuarto lugar.
Spain is in fourth

en el cuarto piso
on the fifth floor US , on the fourth floor Britain ..... I have seen this before and I have no idea where the publishers of got this information but in any city I've ever been the fourth floor is the fourth floor and the fifth is the fifth. Anybody have a different experience?
