null

As there is no valid date. Try like

> chrono.parseDate('2005-12-01')
2005-12-01T06:30:00.000Z

The problem is that even if we want to tell chrono to recognize 2005 as year by adding a custom parser, the result will still be discarded by refiner.
So i was unable to find a way for chrono to parse 2005 at this moment.
