How to add events in `XamForms.Controls.Calendar`?

I am using XamForms.Controls.Calendar for showing calendar in my application, I have added this package in all platforms.

Added following codes in xaml:

<StackLayout>
        <controls:Calendar  
            HorizontalOptions="FillAndExpand" 
            VerticalOptions="CenterAndExpand"  
            x:Name="calendar" 
            DateClicked="CurrentDate"/>
    </StackLayout>

In c#:

XamForms.Controls.Calendar calendar = new XamForms.Controls.Calendar()
            {
                WidthRequest = 300,
                HeightRequest = 300
            };
        }
        public async void CurrentDate(Object sender, EventArgs args)
        {
            var dateSelect = calendar.SelectedDate;
        }

I need to add events for dates in the calendar like school day, school mass or exam(Please see the screenshot added below). Is this possible in XamForms.Controls.Calendar?
