Norwegian doesn't use «.» as a date separator, we use - (as in, 2015-10-03).. as a date separator is awful.riiight, don't ever learn Norwegian. ;o)
Arnt is obviously confusing Norwegian with Polish, where you write “3.10.2015” or “3 X 2015”.
If you're more of a traditionalist, you'd probably write «3. oktober 2015», where the «.» isn't a separator, it's punctuation to convert the 3 into an ordinal number.
Trailing “.” works cardinal-to-ordinal converter in Polish too. However, most of the time use of the suffix is optional, and in fact you should not use it in dates when you spell out the month: “3 października 2015” (even though 3 is ordinal here).
