The date:week-in-year function returns the week of the year as a number. If no argument is given, then the current local date/time, as returned by date:date-time is used as the default argument. For the purposes of numbering, counting follows ISO 8601: week 1 in a year is the week containing the first Thursday of the year, with new weeks beginning on a Monday.

The date/time string specified as the 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.
