Attempting to construct a date using a mixture of ISO week and Gregorian date fields is nonsensical, and could yield unexpected results. In the context of an ISO year, the concept of a 'month' or 'day of month' has no meaning. In the context of a Gregorian year, the ISO week has no meaning. Users should take care to keep Gregorian and ISO date specifications separate.
Attempting to construct a date using a mixture of ISO week and
Gregorian date fields is nonsensical, and will cause an error. In the
context of an ISO year, the concept of a <quote>month</> or <quote>day
