I don't advise putting ANYTHING at all in /etc/default/locale.  That
would affect all logins by all users from all computers.  But supposing
either (1) that's actually what you want, or (2) you're going to set
your variables in your personal login configuration instead....

1) Make sure both locales have actually been generated, via

   dpkg-reconfigure locales

2) Verify they they are both available:

   titan:~$ locale -a
   C
   C.UTF-8
   en_DK.utf8
   en_US.utf8
   POSIX

3) Set the variables:

   titan:~$ export LANG=en_US.utf8 LC_TIME=en_DK.utf8 LC_MEASUREMENT=en_DK.utf8

   (If you want this to be permanent, figure out what dot files to put
   them in.  That's the hardest part of all.)

4) Test:

   titan:~$ ncal
       May 2017
   Mo  1  8 15 22 29
   Tu  2  9 16 23 30
   We  3 10 17 24 31
   Th  4 11 18 25
   Fr  5 12 19 26
   Sa  6 13 20 27
   Su  7 14 21 28

   titan:~$ unset LC_TIME LC_MEASUREMENT
   titan:~$ ncal
       May 2017
   Su     7 14 21 28
   Mo  1  8 15 22 29
   Tu  2  9 16 23 30
   We  3 10 17 24 31
   Th  4 11 18 25
   Fr  5 12 19 26
