way to think more generally, as dates are typically defined only by
their display formats.
ds, has(format %d*)
or
ds, has(format %td*)
would be simple examples.
-findname- (SJ) is of the same flavour, but more versatile.
Note that -tostring- is a Stata command, not a Stata function.
-isnumeric- (origin not explained by you) is presumably a Stata
command, not a Stata macro. Using terminology from outside Stata is
likely to confuse or bemuse.
All that said, -tostring- won't usefully save numeric date variables
as string dates, unless you specify a date format.
