If -date- is a daily date variable then
list date if date == mdy(3,31,2011)
will list all instances of that date in the variable -date- in your data.
That won't be very interesting. You will probably find something like
list if date == mdy(3,31,2011)
more helpful. Note that
31mar2011
as your wrote it can't mean anything in this context, as it can't be
the name of a variable or scalar, and it can't be a literal string as
it is not delimited by " ". (Nor would a literal string be any use
here as dates in Stata are numeric.)
