How to: Return Quarter by Month

This is how we can get specified quarter by month. Example code

private string returnQuarterPeriod(string month)
    {
        string strReturn = "";
        try
        {
            int iMonth = DateTime.Parse(month).Month;
            if (iMonth <= 3)
            { return "1"; }
            else if (iMonth >= 4 && iMonth <= 6)
            { return "2"; }
            else if (iMonth >= 7 && iMonth <= 9)
            { return "3"; }
            else if (iMonth >= 10 && iMonth <= 12)
            { return "4"; }
            else
            {
                //Something probably is wrong 
                return "0";
            }
        }
        catch (Exception ex)
        {
            throw ex;
        }
        return strReturn;
    } 

Hope this helps!
