How to modify months names in context

Question

I would like to change months names in context, in tex \month define the month number, names of months can be redefined with \ifcase Change month names in \today command

How can I do the same in context (modify names of months appearing with \date command), appears as \month unavailable in context.

Update

Answer 1

If you don't want to change the main language of your document (using \mainlanguage[…] then you can redefine the months using \setuplabeltext:

\setuplabeltext
  %% [en]  %% for a language specific setting
  [january=J,
   february=F]

Furthermore, if you want to change the date format used by \date, you can do so with \setuplanguage:

\setuplanguage
  %% [en]  %% for a language specific setting
  [date={year, \thinspace–\thinspace, mm, \thinspace–\thinspace, dd}]
