The following are examples of custom date or time formats that are not valid ISO or W3C format normalizations, normalized to a different dating system

<p>Alhazen died in Cairo on the
<date when="1040-03-06"
  when-custom="431-06-12"> 12th day of Jumada t-Tania, 430 AH
 </date>.</p>
<p>The current world will end at the
<date when="2012-12-21"
  when-custom="13.0.0.0.0">end of B'ak'tun 13</date>.</p>
<p>The Battle of Meggidu
(<date when-custom="Thutmose_III:23">23rd year of reign of Thutmose III</date>).</p>
<p>Esidorus bixit in pace annos LXX plus minus sub
<date when-custom="Ind:4-10-11">die XI mensis Octobris indictione IIII</date>
</p>

Not all custom date formulations will have Gregorian equivalents.

The when-custom attribute and other custom dating are not contrained to a datatype by the TEI, but individual projects are recommended to regularize and document their dating formats.

notBefore-customspecifies the earliest possible date for the event in some custom standard form.

<date when-custom="1598" calendar="#julian"
 datingMethod="#julian">1598</date>. by Iohn Stow
Citizen of London.

In this example, the calendar attribute points to a calendar element for the Julian calendar, specifying that the text content of the date element is a Julian date, and the datingMethod attribute also points to the Julian calendar to indicate that the content of the when-custom attribute value is Julian too.

<date when="1382-06-28"
 when-custom="6890-06-20" datingMethod="#creationOfWorld"> μηνὶ Ἰουνίου εἰς <num>κ</num> ἔτους <num>ςωϞ</num>
</date>

In this example, a date is given in a Mediaeval text measured "from the creation of the world", which is normalised (in when) to the Gregorian date, but is also normalized (in when-custom) to a machine-actionable, numeric version of the date from the Creation.
