I got the following error when running:

```julia
julia> t = Date(2014, 1, 31)
ERROR: UndefVarError: Date not defined
Stacktrace:
 [1] top-level scope at none:0

```

Julia version 1.1.0

Is there any possible explanation for this? I didn’t find any similar case.

Thanks. I thought it was needed only for the older version of Julia
