The `date:day-abbreviation` function returns the abbreviation of the day of the week of a date. If no argument is given, then the current local date/time, as returned by `date:date-time` is used the default argument. The date/time string specified as the argument is a left or right-truncated string in the format defined as the lexical representation of `xs:dateTime` in one of the formats defined in [XML Schema Part 2: Datatypes]. The permitted formats are as follows: `xs:dateTime` (`CCYY-MM-DDThh:mm:ss`) `xs:date` (`CCYY-MM-DD`) If the date/time string is not in one of these formats, then the empty string (`''`) is returned. The result is a three-letter English day abbreviation: one of `'Sun'`, `'Mon'`, `'Tue'`, `'Wed'`, `'Thu'` or `'Fri'`. ## Implementations The following XSLT processors support `date:day-abbreviation`: SAXON from Michael Kay (version 6.4.2) Xalan-J from Apache (version 2.4.D1) 4XSLT, from 4Suite.
