                    }
                }
            }
        }
    }
}
replaceWordsDates();
</script>

this one is to change the word for the dates you can add to it

<style type="text/css">
div.blogheader, .caption {
font-family:arial;
text-transform:lowercase;
font-size:21px;
line-height:14px;
font-weight:bold;
color:#FF0000;
text-align: left;
}
</style>

this edits the format of the date. you change and add things to it
