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").

One step further, thanks.
But why does
\edef\thedate{\rawdate[]}\writestatus{***}{\meaning\thedate}
result in
** > macro:->unknown march 2013
instead of 20 march 2013?

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.

I see. 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.

\starttext
\writestatus{***}{\cldcontext{os.date("\letterpercent Y\space\letterpercent m\space\letterpercent d")}}
\stoptext
> I am most unhappy with this, because fixing the current date in some macro shouldn't be impossible.
\starttext
\writestatus{***}{\number\normalyear \space \number\normalmonth \space \number\normalday}
\stoptext

This should be “month,space,day,space,year”, “space” in this list is a keywords to add a space between the entries.
