<date> is a generic element that contains a month, day, and/or year in any format. It should be used for dates which merit encoding and do not fall under <unitdate>. It may be entered as text or numbers and as a single date or range. The NORMAL attribute may be used to facilitate machine date reading and comparison, using YYYYMMDD, etc.
A standard numeric form of the date (YYYYMMDD, etc.) can be specified with the NORMAL attribute to facilitate machine comparison of dates for searching, for example, 19480101/19980401 (YYYYMMDD/YYYYMMDD), or 1948/1998 (YYYY/YYYY). The TYPE attribute can be used to supply a more specific designation, for example, “life,” “flourish,” “depiction,” “publication,” or “acquisition.” The CERTAINTY attribute may be used to indicate the degree of precision in the dating, for example, “circa,” “approximately,” or “after.” The CALENDAR attribute, which has a default value of “gregorian,” specifies the calendar from which the date stems. The value “ce” (common or Christian era) is the default for the ERA attribute.
<date> may be used within <change>, <chronitem>, <creation>, <entry>, <event>, <extref>, <extrefloc>, <imprint>, <item>, <label>, <legalstatus>, <p>, <physdesc>, <physfacet>, <publicationstmt>, <ref>, <refloc>, <subtitle>, <title>, <titlepage>, <titleproper>, and <unittitle>.
