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 1 below works and option 2 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 ----- On Fri, Feb 21, 2025 at 12:13 PM Wolfgang Schuster < wolfgang.schuster.lists@gmail.com> wrote:

Any thoughts why the following doesn't work?
\currentdate[d:persiannumerals]
It just outputs the normal digits.
In contrast, these work:
\currentdate[d:abjadnumerals] \convertnumber{persiannumerals}{\normalday}
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.
