Default Locales differences??
 

Im in process of installing Debian Srv...now it asks me for the above Default Locale.

Any places where I can see the diff btw the Locales??
Like btw da_DK.UTF8 and en_DK.UTF8

Any good sites that explains or show the diff???

da means danish language.

DK means country denmark.

UTF-8 means unicode characters utf-8 format.

en means english.

I think that OP knows what it means, he wants to know what's the difference in how they work

Yes, please I want to know the differences btw the specific 2 locales. As both are for country DK!
What does it mean one is danish and the other english? I mean which effect does it have if I install one over the other.

Maybe en_DK.UTF8 means the actual day names will be in english but formats will be still danish??

da_DK.UTF8 will be danish day names w danish format??

You can see locale description in /usr/share/i18n/locales/<LOCALE>, for example /usr/share/i18n/locales/en_DK

Well, Im in middle of installation process so I was looking for some external site that could guide me in choosing the correct Locale :)

I am not aware of such site. I uploaded all locales to my website, it's only 6.2 Mb: http://drabczyk.org/locale/locales/. For example for en_DK: http://drabczyk.org/locale/locales/en_DK

The locale will control the following things:
1. The language used by your desktop and programs
2. The sorting order: e.g. Danish puts æ after z
3. Number format: 1.000,12 versus 1,000.12
4. Paper size: USA doesn't use international sizes
5. Weights and measures: USA doesn't use metric system
6. 12 or 24 hour clock as default
7. Default currency
8. Date layout: 01/02/15 or 15/02/01 or 02/01/15
and probably a few other things...
