There is a nasty problem when defining the \date.
First approach:
*** > macro:->\date
\def\thedate{\date}\writestatus{***}{\meaning\thedate}
Alas, I get lateron a luatex error on \date:
! LuaTeX error [string "\directlua "]:1: invalid escape sequence near '\d'.
Second approach, use \edef to get an expanded value.
\edef\thedate{\date}\writestatus{***}{\meaning\thedate}
*** > macro:->\date
Alas, the date is still the unexpanded macro and not something like 20 march 2013.
How to?

All commands with optional argument aren’t expandable and \date *has* two optional argument. To get now the date in the output you can either use the expandable \rawdate[] command (the brackets are necessary) or you use \ctxcommand{currentdate(<specification>,<language>)} (language can also be "false").

Provide a *working* minimal example because when I run this example \starttext \rawdate[] \stoptext I get “march unknown, 2013” as output. When I use now (instead of \currentlanguage you can also use a language tag, e.g. "nl") \starttext \ctxcommand{currentdate("month, ,day, , year","\currentlanguage")} \stoptext I get as output “March 20 2013”. The problem with \rawdate is that no language is passed and context doesn’t convert the labels for the month/years and also the day results in a default string, i.e. it produces the “unknown” string.

But this is not working too. Following your suggestion I now get: \edef\thisdate{\ctxcommand{currentdate("month, ,day, , year","\currentlanguage")}}\writestatus{***}{\meaning\thisdate} *** > macro:->\labeltext {march} 20 2013 The problem is essentially the same. I am most unhappy with this, because fixing the current date in some macro shouldn't be impossible. And why all those extra ,s in month, ,day, , year? I would suggest that besides \currentdate one should be able to also use \currentdate[month][day][year][language], \currentdate[day][mont][year][language],etc. And then be able to store the expansion in a macro. Is it possible to incorporate this in the next beta? By the way, the \time and \currenttime pose the same problem, here even \rawtime seems nonexistent.
