I am not sure if the best way to do this is in Coldfusion or SQL.

I would like to output calendar months based on the current month.

For example, with this month being April, I would like to output one month prior(March) and four months into the future(May, June, July, August).

So, my results would like March, April, May, June, July, August.

The following is the hardcoded code I am using but naturally I do not want to have to change the month name and month number every month.

<a href="page?m_id=3" onclick="change_month(3)"><h6  class="" >March</h6></a>
          <a href="page?m_id=4" onclick="change_month(4)"><h6  class="active" >April</h6></a>
            <a href="page?m_id=5" onclick="change_month(5)"><h6 >May</h6></a>
            <a href="page?m_id=6" onclick="change_month(6)"><h6 >June</h6></a>
            <a href="page?m_id=7" onclick="change_month(7)"><h6 >July</h6></a>
            <a href="page?m_id=8" onclick="change_month(8)"><h6 >August</h6></a>
            <a href="/secc_chicago/includes/events_by_month.cfm?m_id=9" onclick="change_month(9)"><h6 >September</h6></a>

How about something like:

<cfset t = DateAdd("m", -2, now())   />
<cfoutput>
    <cfloop from="0" to="6" index="n">
        <cfset t = DateAdd("m", 1, t) />
        <a href="page?m_id=#Month(t)#" onclick="change_month(#Month(t)#)"><h6  class="" >#MonthAsString(Month(t))#</h6></a>
    </cfloop>
</cfoutput>

....but you might need to change the final link.

You could use either. But if it's just month name and number you need, I'd probably use ColdFusion

            <!--- get date last month --->
           <cfset startDate = dateAdd("m", -1, now())>

           <cfoutput>
           <cfloop from="0" to="4" index="x">
                  <cfset monthNumber = datePart("m", dateAdd("m", x, startDate))>
                  <!--- requires CF9. for CF8 just use cfif/cfelse ---->
                  <cfset className =  monthNumber eq month(now()) ? "active" : "normal">
                  <a href="page?m_id=#monthNumber#" onclick="change_month(#monthNumber#)">
                            <h6  class="#className#">#MonthAsString(monthNumber)#</h6>
                  </a>
           </cfloop>
           </cfoutput>

Oops.. too slow ;-)  I assumed the last link was a copy / paste error.  Just don't forget to adjust the css class for the "current" month.

Also typo correction, this:

          <cfloop from="0" to="4" index="x">

should be:

          <cfloop from="0" to="5" index="x">

The only issue seems to be that the class="active" seems to always default to April, the current month.

That was just me guessing from your original code. But the logic can be anything you want.  For example, if you're linking to the same page, you could use the #url.m_id# value to determine what's "active"

         <!--- use whatever default you want, current month ie #month(now())#, 0, etc... --->
         <cfparam name="url.m_id" default="0">
         ....
         <cfset className =  monthNumber eq url.m_id ? "active" : "normal">
