It's not even that hard. Just apply templates to the following
siblings whose position() is less than $cols:

<xsl:variable name="cols" select="3" />

<xsl:template match="tripdates">
  <xsl:apply-templates select="month[position() mod $cols = 1]"/>
</xsl:template>

<xsl:template match="month">
  <tr>
    <xsl:apply-templates mode="table"
      select=". | following-sibling::month[position() &lt; $cols]" />
  </tr>
</xsl:template>

<xsl:template match="month" mode="table">
  <td><xsl:value-of select="."/></td>
</xsl:template>
