Windows.UI.Xaml.Controls.DatePicker.MonthVisible
June 22, 2022 ยท View on GitHub
-description
Gets or sets a value that indicates whether the month selector is shown.
-xaml-syntax
<DatePicker MonthVisible="bool"/>
-property-value
true if the month selector is shown; otherwise, false. The default is true.
-remarks
By default, the DatePicker shows ComboBox elements to select the month, day, and year. Set MonthVisible to false to hide the ComboBox that displays or changes the month component of a date.
Here's the picker with the month field hidden.

It's typically not useful to show the day field without the month for context. A more common usage is to hide both the day and month, and show only the year, like this.
<DatePicker x:Name="yearDatePicker" Header="In what year was Microsoft founded?"
MonthVisible="False" DayVisible="False"/>
