Portuguese cal uncapitalized problem

[Daniel Santos <hello@xxxxxxxxxxxxxxx>]

Hi everyone.
I would like for the Portuguese months and days of the week of `cal`, to 
be capitalized.
 . Can anyone do this?
 . Should I do this? Where can I find the days of the week and the 
months translation? (it does no seem to be in the 
https://translationproject.org/POT-files/util-linux-2.37-rc2.pot file)
