@kuzma-sasha thanks for this, can you describe what problem are you fixing and how to replicate it?

Because if i select a date or a day then when i close and reopen the datepicker i see it's already selected...

Hello) There is the following situation:

1. open the calendar;
2. choose the date from the calendar - March 10, 2017 (03-10-2017);
3. close the calendar;
4. open the calendar and we can see selected date and selected month, it is right;
5. change date manually with other month, for example February 11, 2017 (02-11-2017);
6. close the calendar (using focus out);
7. open the calendar;
8. result: we can see calendar with March month, and we don's see selected day;
