XSLT Sort and choose last items problem

Hello.

I am trying to display the last 5 "days" from an XML file, sorted in
descending order.

Sample XML snippet:
<journal>
	<year>
		<month date="1">
			<day date="1">
				<contents/>
			<day date="2">
			...
		</month>
		<month date="2">
			<day date="1">
				<contents/>
			<day date="2">
			...
		</month>
		...
	</year>
</journal>

I currently use XSLT:
(Snippet:)
<xsl:for-each select="journal/year/month[last()]">
	<xsl:for-each select="day[position()>last()-5]">
		<xsl:sort order="descending" select="@date"/>
		<item>
			<xsl:call-template name="item-contents"/>
		</item>
	</xsl:for-each>
</xsl:for-each>

This does not quite do what I want to do. This is because I am unable to
select the last 5 days when they span "month" elements. For example,
when the last day in the XML file is 2 Feb, I want to select (in this
order) 2 Feb, 1 Feb, 31 Jan, 30 Jan, and 29 Jan. I can't figure out how
to select the days from January.

I hope I've explained that well enough.

Sincerely,
