summary statistics for date variables
-------------------------------------

    ^datesum^ date_varlist [^if^ exp] [^in^ range], ^F^ormat^(^date format^)^]


^by^ ... ^:^ may be used with ^datesum^; see help ^by^


Description
-----------

^datesum^ displays summary distribution statistics for date variable(s) in date
display format.  The variables in the date_varlist are assumed to be stored as
Stata elapsed-dates.

The output display format is:
    1) from the ^format()^ option if specified, otherwise
    2) the display format of the variable if a valid date format, otherwise
    3) %dN/D/Y  (eg. 03/31/99 )


Options
-------

^format(^%d___^)^ should be a valid date display format.  The default is to use
the variable display format if a valid date format, otherwise %dN/D/Y.


Remarks
-------

^datesum^ is a wrapper for the -summarize- command, allowing for the display of
selected summary statistics in a date display format.  Returned results are
those left behind by -summarize varname, d- for the last variable in the
date_varlist.
