boost counting_range doesn't include iterating the last value

Question

I have this code:

void CMeetingScheduleAssistantApp::InitDateTransArrays()
{
    if (theApp.UseTranslationINI() || theApp.GetProgramLanguage() == LANGUAGE_MALAGASY)
    {
        CString strKey;

        // Days of the week
        for (auto const &i : boost::counting_range(0, 7))
        //for (int i = 0; i <= 6; i++)
        {
            strKey.Format(_T("Day%d"), i);
            // AJT v17.1.3 Now use our own methods
            m_aryDateTrans[DATE_TRANS_DAY].Add(GetStringFromTranslationINI(_T("Days"), strKey));
            m_aryDateTrans[DATE_TRANS_DAY_SHORT].Add(GetStringFromTranslationINI(_T("DaysAbbreviated"), strKey));
        }

        // Months of the year
        for (auto const &i : boost::counting_range(1, 13))
        //for(int i = 1; i <= 12; i++)
        {
            strKey.Format(_T("Month%d"), i);
            // AJT v17.1.3 Now use our own methods
            m_aryDateTrans[DATE_TRANS_MONTH].Add(GetStringFromTranslationINI(_T("Months"), strKey));
            m_aryDateTrans[DATE_TRANS_MONTH_SHORT].Add(GetStringFromTranslationINI(_T("MonthsAbbreviated"), strKey));
        }
    }
}

Notice the for loops I had then set to 0 - 6 and 1 - 12 respectively. I found out that they had to be 0 - 7 and 1 - 13. It iterates UPTO the last number, it doe snot include the last number itself!

So this is misleading:

Please confirm.
