I am saving recurring calendar events programatically. Here is my code.

SPSite site = new SPSite(SPContext.Current.Web.Url);
            using (SPWeb web = site.OpenWeb())
            {
                SPList list = web.Lists["Bookings"];
                SPListItem recEvent = list.Items.Add();
                try
                {
                    recEvent["Attendees_x0020_Number"] = "5";

                    #region startdate
                    string strtDate = txtStartDate.Text;
                    string day = strtDate.Substring(0, 2);
                    string month = strtDate.Substring(3, 2);
                    string year = strtDate.Substring(6, 4);
                    string hour = ddlStrtHour.SelectedValue;
                    //string hour_int = hour.Split(' ')[0];
                    //string am_pm = hour.Split(' ')[1];
                    string mins = ddlStrtMins.SelectedValue;

I am facing issue when i add a new event which is recurring Daily Every Weekday and End After 10 Occurances, the Reccurence rule formed is

<recurrence><rule><firstDayOfWeek>su</firstDayOfWeek><repeat><daily weekday="TRUE" /></repeat><repeatInstances>10</repeatInstances></rule></recurrence>

But when i look at the Calendar view than i get the entries Starting on next day of the start date as seen in fig: I had set Start Date as 10/09/2012 but the event starts from 11/09/2012 and weekdays are considered from Tuesday to Saturday instead of Monday To Friday. I dont know why this is happening.

enter image description here The view which consists of all instances of recurring items: enter image description here

Please help me to sort out why the week days are considered from Tuesday to Friday, this issue happens only when i add entry programatically, works fine when adding event through Sharepoint UI.also why is Start Date gets saved as 11/09/2012 when the input was 10/09/2012?

The issue was with setting the TimeZone while saving. Remove it/ Set it correctly. Should work fine
