No, but the example that the CO gives is bad. Description says "Du skal have fundet cacher i 10 Europæiske lande, hvoraf de 7 skal være taget indenfor 30 dage (f.eks. fra 5. juli - 5. august)" which translates to "You must have found caches in 10 European countries, of which 7 must be taken within 30 days (eg. From July 5 to August 5)".
Well, July 5 to August 5 is 32 days (27 days in July + 5 days in August). So is it 30 or 32?
