Problem Starting Weekly Sprints (duration)

[v_grytsay]

I can’t set the sprint date correctly

when you select a date in the calendar, 0020 is set. 

if you set the date manually, swears at a long sprint

The problem arises when choosing weekly sprints.

after editing the date, the sprint starts with the year 0020

If you type the dates manually, then everything works fine

The system time is correct
