Description

The value space of xs:gDay is the periods of one calendar day recurring each calendar month (such as the third of the month); its lexical space follows the ISO 8601 syntax for such periods (i.e., " -- -DD”) with an optional timezone.

When needed, days are reduced to fit in the length of the months, so ---31 would occur on the the 28th of February of nonleap years.

Restrictions

The period (one month) and the duration (one day) are fixed, and no calendars other than the Gregorian are supported.

Example

Valid values include "---01", "---01Z", "---01+02:00", "---01-04:00", "---15", or "---31".

The following values would be invalid: "--30-" (the format must be "---DD"), "---35" (the day is out of range), "---5" (all the digits must be supplied), or "15" (missing leading "---").
