Is there a way to test the validity of a date other than

```julia
function test_date(y::Int, m::Int, d::Int)::Nullable{Date}
    try
        return Nullable{Date}(Date(y, m, d))
    catch
        return Nullable{Date}()
    end
end

```

Seems like there should be a simple `test` function?

See `Dates.validargs`.

sorry, only in `v0.6`. In `v0.5.2`, look at `@edit Date(2000,1,1)`, and you can construct a test using the source which has not been factored out in that version.
