The year 1953
Hmm, as you can tell, I don't master the Polish language yet, so I'm not sure about that difference.
For the year 1953, I'd say: w tysiąc dziewięćset pięćdziesiątym trzecim roku.
Not sure this is what you asked for tho.
the number system very complicated indeed.
And that's just a part of the language ^^
