I typed in the day and the month. Then, since we are in the 21st century as far as I can tell, I typed in "2100" for the century. It didn't like that. I called the place and explained that if they had wanted me to type in the YEAR they should have used what all the world uses as an abbreviation: "Y Y Y Y" rather than "C C C C".
Arthur, sorry for your misunderstanding. The language is not dd/mm/yyyy [day/month/year] as you have incorrectly believed.
Being American I can see why you thought the world revolved around the US Dollar and English being the language of Science and Aircraft Control, however being a world economy as such, dd/mm/cccc is correct, you just need to change your language to Catalan* and enter Dia (English for day), Mes (English for month) and Curs (English for year)...so as you can easily see dd/mm/cccc Dia/Mes/Curs is in correct form.

Of the 9,412,637 people worldwide that can speak Catalan you are apparently not one of them
