create any class in your project.
put this static member in this class

C#

public class AnyClass
    {
        public static int ind = 0;
        public static string lastDay = "";
    }

add your asp.net project a global.asax file

and configure your application_start and session_start area

C#

protected void Application_Start(object sender, EventArgs e)
       {
           AnyClass.lastDay = DateTime.Now.ToShortDateString();
       }

       protected void Session_Start(object sender, EventArgs e)
       {
           string toDay = DateTime.Now.ToShortDateString();

           // this will work only one times in a day. hour check the time after a new day. AnyClass.lastDay != toDay check if your computer time is am and pm. i didnt test clearly but i hope this will help you.
           if (DateTime.Now.Hour == 0 && (AnyClass.lastDay != toDay) && AnyClass.ind != 0)
           {
               AnyClass.ind = 0;
               AnyClass.lastDay = toDay;
           }
           AnyClass.ind++;
       }

dont forget this will took in session. you can manage your sessions time in web.config file or under iis.

call your AnyClass.ind in your project anywhere
