BTW why doesn't \setuplabeltext exist in the mtx-server-ctx-help? It does exist in setup-en.pdf and shows that it is an instance of \setupLABELtext.

the following outputs "farsi" instead of "fa". is this the reason the translation of jalali month does not kick in?

strangely either of the following two lines changes the month name.

------
\setuplabeltext[en][february:jalali=test]
\setuplabeltext[fa][february:jalali=test]
\currentlanguage[month:jalali]

I'm confused. why isn't the data in lang-txt.lua used?
strangely, the following outputs the correct translation of second jalali month in farsi regardless of the above \setuplabeltext commands:

----
\ctxlua{context(languages.data.labels.texts['february:jalali'].labels.fa)}

For Jalali dates and Persian numbering, I can get the following to work:

\persiandecimals{\rawdate[jalali:to,d]}/\persiandecimals{\rawdate[jalali:to,M]}/\persiandecimals{\rawdate[jalali:to,y]}

but the following does not work and throws an error:

\persiandecimals{\currentdate[jalali:to,d]}

If I want to get the output for different date, option 2 below works and option 1 does not.

---------
% option 1
\persiandecimals{\begingroup\setdate[m=5]\rawdate[jalali:to,y]\endgroup}
% option 2
{\begingroup\setdate[m=5]\persiandecimals{\rawdate[jalali:to,y]}\endgroup}
----------

does \setdate expand to something non-empty?

note that with the above ideas, we cannot get "mm" with leading zeros to work because
\persiandecimals drops the leading zero. the following ugly hack works if I insist on using
\currentdate to format the output and I want Indic digits.

--------
\startluacode
  function persmap(s)
  local stream  = tostring(s)
  local mapping = languages.decimals.persian
  local gsub    = string.gsub
  return mapping and gsub(stream, ".", mapping) or stream
  end
\stopluacode

\def\persmap#1{\ctxlua{context(persmap("#1"))}}
\def\mycurrentdate[#1]{\persmap{\rawdate[#1]}}
\mycurrentdate[jalali:to,dd,/,mm,/,y]
--------

even with \mainlanguage[fa] and \language[fa] I don't get the month names translated to persian labels. why?

------
\mainlanguage[fa]
\language[fa]
\starttext
\currentdate[month:jalali]
\stoptext

persiannumerals aren't considered a conversion method for the underlying
Lua mechanism while there exists a method for \convertnumber on the TeX
side.

Both system are separate (to a certain degree) but the TeX side borrows
the conversion vectors from the Lua mechanism.
