Vertical text align for multiple lines - html

Question

1) I was wondering how I can have this text all in one block aligned centerally in the page (both vertically and horizontally).
2) I also want each line of text flush with the other lines of text. Any ideas?

Example fiddle: http://jsfiddle.net/T2T69/1/
with the markup you provided you can remove the absolute position from body and add this style
html, body {
height: 100%;
margin: 0;
padding: 0;
}
body {
display: table;
width: 100%;
}
body > .row {
display: table-cell;
vertical-align: middle;
text-align: center;
}

As a side note, I would suggest to use a cleaner markup instead of nested div, something like
<section>
<time datetime="2014-05-05">5TH MAY 2014</time>
<h1>HIGHGATE MARKET & FAIR <span>ARTS, CRAFTS, ..., FOODS</span></h1>
<p>Lauderdale House Waterlow Park Highgate Hill Highgate N6 5HG</p>
</section>
