Function Syntax

number date:day-in-week(string?, string?)

The date:day-in-week function returns the day of the week given in a date as a number. If no argument is given, then the current local date/time, as returned by date:date-time is used the default first argument.

The date/time string specified as the first argument is a 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:

If the date/time string is not in one of these formats, then NaN is returned.

The second argument is the name of a date format (declared by date:date-format) that is used to work out the numerical day of the week of the specified date. For details about how the format pattern is constructed and used, see date:date-format). The numbering of the days of the week always begins at 1.

An implementation of this extension function in the EXSLT date namespace must conform to the behaviour described in this document.
