Dates in Danish are wrong

Reported by: runemoennike@… Owned by: fredrik
Component: datetime Data Locale: da
Phase: rc Review:
Weeks: Data Xpath:


According to the Danish Language Council (DSN), dates in machine writing are written on the form d.m.yyyy, yyyy-mm-dd, or yy-mm-dd. Not with slashes as shown in the CLDR.

Source: http://sproget.dk/raad-og-regler/artikler-mv/svarbase/SV00000046 which is part of DSN's knowledge base. Summary in English, my own translation:

  1. The international system is acceptable and widely used: yyyy-mm-dd, yy-mm-dd, or without dashes at all.
  2. Traditionally, dates are written as d.m.yyyy or d.m.yy without zero padding.
  3. Using forward slashes is prevalent in hand writing, but in the shape d/m yyyy (space between month and year, not slash).
  4. Writing dates with dashes should be avoided in machine written texts.

This is related to http://unicode.org/cldr/trac/ticket/7657 in which for some reason Apple is taken as the authority over DSN. Maybe it would be possible to collaborate with DSN to get this resolved? They run both a phone hotline and an email service. I notice you worked with them in another ticket, and it seems like the best way to go.

Please note that there is a heavy English influence on Danish culture, meaning dates can be found written in all sorts of formats on Danish websites. Of course, that does not make it any more correct.

Our vetter agrees with this report. Also, there are inconsistencies across Danish data that should be worked out by vetters (possibly in v34).

From our vetter:
We have discussed this. There are no clear guidelines from official hand for Danish. The reference in the ticket is 12 years old and is only a suggestion and a summary on what is most common but it is not taking UI into account.
For our purposes, we prefer to keep the current date format, we find it easy to read and we like that it’s different from the time format.

we should do this in the survey tool in v34.

Pushing to 34 based on Kristi's comment.

Looks like votes are split. Fredrik, have you confirmed with your vetter that this should not change?

Replying to kristi:

Many times. This is not a new issue. :-) It seems like there are just two camps on this.
