When reading the date portion, Calc first checks to see if it is an
ISO 8601 week-numbering date; if the string contains an integer
representing the year, a ``W'' followed by two digits for the week
number, and an integer from 1 to 7 representing the weekday (in that
order), then all other characters are ignored and this information
determines the date. Otherwise, all words and numbers are isolated
from the string; other characters are ignored. All words must be
either month names or day-of-week names (the latter of which are
