Following Alfonso's suggestion, this is the code I've gone for. Where #blogdate is a span element.

<script type="text/javascript">    
google.load("feeds", "1");
function feedLoaded(result) {
    if (!result.error) {
          var pubDate = result.feed.entries[0].publishedDate;
          var date = new Date(pubDate);
          var months = Array("January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December");
          var pubDateString = date.getDate() + " " + months[date.getMonth()] + " " + date.getFullYear()
          $('#blogdate').text("last post: '" + result.feed.entries[0].title + "' on " + pubDateString); 
    }
}
function OnLoad() {
   var feed = new google.feeds.Feed(**XML URL**);
   feed.load(feedLoaded);
}
google.setOnLoadCallback(OnLoad);
</script>

It is likely that your blog supports RSS. RSS provides an xml file with your recent updates so you could for example use a javascript / jQuery based parser to parse this file and get your last post date, title and link.
