OnDateClickListener returning an incorrect date

[zhangzhu95]

I scrolled to January of 2020, and I noticed that when I choose 30 or 31 of december 2019, the library is telling that the year of that date belongs to 2020, which is incorrect.

Steps to reproduce :

1. Scroll to January 2020
2. Choose 30/12/2019

Actual Result:
The OnDateClickListener is returning a DateData with the year 2020

Expected Result:
The OnDateClickListener should return a DateData with the year 2019.
