Hi Muthu,  
 
Thank you for the update. 
 
We checked your requirement “I would like to show the no of days. If it's sunday and local holidays has been blocked. Saturday as 0.5 days for this calculation" and You can achieve your requirement by using the SelectionChanged event in SfCalendar. We’ve prepared the sample for the same. Please find the link below for the sample, 
 
Code Snippet: 




private void Calendar_SelectionChanged(object sender, Syncfusion.SfCalendar.XForms.SelectionChangedEventArgs e) 
{ 
    double noOfDays = e.DateAdded.Count; 
    double count = 0; 
 
    foreach (var item in e.DateAdded) 
    { 
        if (item.Date.Date.DayOfWeek == DayOfWeek.Saturday) 
        { 
            count = +0.5; 
        } 
    } 
 
    noOfDays = noOfDays - count; 
 
    App.Current.MainPage.DisplayAlert("Selected Days", noOfDays.ToString() + " Days", "ok");
