   We are facing this issue and searching for a workaround.
   A simple workaround with the Date constructor is to do something like this

   const date = new Date(year, month, day);
   date.setFullYear(year);
   

   Display of years on four digits can also be fixed with leading zero with help of the String.padStart method for example.

   For anyone facing this issue, it seems the following patch works in my case. Could also be a starting point to propose a PR to dayzed library.
