=ISO 8601=<br />
<br />
The '''International Standards Organisation''''s standard, number '''8601''' is an international standard for date and time representations. It is used for all date-time representations in microformats.<br />
<br />
==Overview==<br />
<br />
For a plain-language overview of ISO 8601, we recommend the [http://www.cl.cam.ac.uk/~mgk25/iso-time.html ISO 8601 summary by Markus Kuhn].<br />
<br />
==Microformats==<br />
<br />
Microformats using ISO8601 include:<br />
<br />
*[[hAtom]]<br />
*[[hCalendar]]<br />
*[[hCard]]<br />
*[[hReview]]<br />
*...<br />
<br />
==<nowiki>RFC 3339</nowiki>==<br />
<br />
RFC 3339 defines a profile of ISO 8601 for the use in Internet protocols and standards.<br />
<br />
*It explicitly excludes durations and dates before the [http://en.wikipedia.org/wiki/Common_era common era].<br />
*The more complex formats like week numbers and ordinal day are not permitted (see <nowiki>RFC 3339</nowiki>, section 5.6). <br />
<br />
Microformats {{should}} use <nowiki>RFC 3339</nowiki>.<br />
<br />
==Issues==<br />
* How should dates before the common era be marked up? [[User:AndyMabbett|Andy Mabbett]]<br />
* If a web page is created or edited by a non-technical human, it is unfriendly to expect them to work in ISO date format. [[User:CharlesBelov|Charles Belov]]<br />
