WPF Calendar control provides you with the basic UI to begin the calendar integration in your application. The top two arrow-heads, allow you to navigate back and forth to other months and select the desired date from the calendar.
The navigation also supports year view and decade view, so, you can select the desired year and month very easily. Click on the month name (in our case, it's August 2017) present at the top, to navigate to the year view. When you are in the year view, it will show you the Jan–Dec month range, and clicking on the year will navigate you to the decade view where you can select the desired year.
