Hi All,

How do I say "Albert Einstein (March 14, 1879 – April 18, 1955)" using hCard? Specifically, what is the best way of expressing a person's life dates?

"bday" seems like an obvious choice for date of birth. Would adding a term like "dday" be appropriate for date of death?

Or would it be better to use "dtstart" and "dtend" from hCalendar? This feels more elegant, except that "bday" is a more semantically precise than "dtstart".

Or maybe some hybrid? perhaps class="bday dtstart" for birthday and class="dtend" for death date?

To go back to the beginning...

One option would be to use both. This may seem a bit convoluted, but hopefully it can be illustrative of how microformats can be overlaid.

<div class="vcard vevent">
    <span class="fn summary">Albert Einstein</span>
(<abbr class="dtstart bday" title="1879-03-14">March 14, 1879</ abbr -
     <abbr class="dtend" title="1955-04-18">April 18, 1955</abbr>)
</div>

A couple notes:
1. Using vevent class name without a surrounding vcalendar class name implies that the entire document is a vcalendar. 2. You could optionally add the class name ddady (or some other semantic, meaninful class name) to the dtend property. (more explanation at [1])
