in thread Localized weekday names

Well, I wanted the list to a) start with Sunday, and b) have the "short" day name.

So I modified your code to something like this: 

perl -MDateTime -le '@wd=map {DateTime->new(locale=> "de", year=>1970,
+month=>1,day=>4+$_)->strftime("%a")} (0..6);print join",",@wd'

Which does work, but for Germany this interestingly produces 
So.,Mo.,Di.,Mi.,Do.,Fr.,Sa.

instead of the desired 
So,Mo,Di,Mi,Do,Fr,Sa

It doesn't look like DateTime can handle %a returning only 2 chars. -- No Idea why :-)

    Hi,

    It doesn't look like DateTime can handle %a returning only 2 chars. -- No Idea why :-)

    That's not it at all. Please see the documentation for DateTime::Locale. You can look up the data used by DateTime::Locale for each locale code, for example, for the one you used, de, at https://metacpan.org/pod/distribution/DateTime-Locale/lib/DateTime/Locale/de.pod, which contains: 

    Abbreviated (format)

Mo.
Di.
Mi.
Do.
Fr.
Sa.
So.

...

Abbreviated (stand-alone)

Mo
Di
Mi
Do
Fr
Sa
So

    So you should use DateTime::format_cldr() with format ccc to print "Abbreviated (stand-alone)", as shown in the docs: 
    $ perl -Mstrict -MDateTime -wlE 'say join", ", map { DateTime->new( lo
+cale => "de", year => 1970, month => 1, day => 4 + $_ )->format_cldr(
+"ccc") } 0 .. 6'

So, Mo, Di, Mi, Do, Fr, Sa

    The way forward always starts with a minimal test.
