There are a number of problems from my POV with the Date Picker
It does not localise correctly on some systems - I am using a UK Mac OSX and both the OS and Chrome are localised to English, UK date formats yet Dato uses US formatting
It is not good for picking dates! because it does not have extended features such as toggle between months, years and decades by clicking on the title area. This makes it very poor for anything other than close dates.
It has some styling issues (like transparency)
There are many very good off the shelf open source date pickers that you could use that are tried and tested
