Question : Sql syntax( datetime) problem

Experts
please see the following sql query and suggest me whether it is correct or wrong .
As it is not giving any o/p.

DateTime dt=DateTime.Today;
using (SqlConnection con = new SqlConnection(Connectionstring.Connection))
{
string query = "select count(InteractionID) from Table_Interaction where reminderDate '" + dt + "' ";
using (SqlCommand cmd = new SqlCommand(query, con))
{
con.Open();
SqlDataReader reader = cmd.ExecuteReader();
while (reader.Read())
{
label2.Text = string.Format("{0}", reader[0]);
}
}

}

For more information please see the images attached for the table design.
Experts I am using Sql server 2005 not sql server 2008.
Thanking you
Anindya
