Lot of 0NaN-aN-aN

Bug description

I am consistently getting this warning in my console:

The specified value "0NaN-aN-aN" does not conform to the required format, "yyyy-MM-dd".

When I pass a new Date() to the DayPicker component.

To reproduce

I cannot reproduce this within a CodeSandbox, but it happens in my project.

Can you share a screenshot/code of the date object causing this?

Other than that if it's not an issue try using moment js. It will make it super easy to work with dates.
