In this article I am going to explain how to get Month name,
number, year and number of days from selected date in asp.net.
Description:
I want to get the month name, number, year and number of
days in selected month.
Implementation:

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
   
<title></title>
    
<script src="https://code.jquery.com/jquery-3.2.1.min.js"></script>

<link href="CSS/bootstrap-3.3.2.min.css" rel="stylesheet" />
   
<link href="Datepicker/css/bootstrap-datepicker3.css" rel="stylesheet" />
   
<script src="Datepicker/js/bootstrap-datepicker.js"></script>  
   <style type="text/css">

  position: absolute;
  top: 33px;
  right: -300px;
  margin: 0;

</style>
</head>
<body>

<table>
            <tr><td>Select date : </td><td><asp:TextBox ID="txtdate" runat="server"></asp:TextBox><div id="custompop"></div></td></tr>

int year = date.Year;
       
string monthname =
date.ToString("MMMM");
       
int nodays = DateTime.DaysInMonth(year,
monthno);
       
lblresult.Visible = true;

Dim nodays As Integer = DateTime.DaysInMonth(year,
monthno)
       
lblresult.Visible = True
       
lblresult.Text = "Month Name : " & monthname & "<br/>Month
