Returns a field to access the week of month based on this WeekFields.
This represents the concept of the count of weeks within the month where weeks start on a fixed day-of-week, such as Monday. This field is typically used with WeekFields#dayOfWeek().
Week one (1) is the week starting on the WeekFields#getFirstDayOfWeek where there are at least WeekFields#getMinimalDaysInFirstWeek() days in the month. Thus, week one may start up to minDays days before the start of the month. If the first week starts after the start of the month then the period before is week zero (0).
For example:<br> - if the 1st day of the month is a Monday, week one starts on the 1st and there is no week zero<br> - if the 2nd day of the month is a Monday, week one starts on the 2nd and the 1st is in week zero<br> - if the 4th day of the month is a Monday, week one starts on the 4th and the 1st to 3rd is in week zero<br> - if the 5th day of the month is a Monday, week two starts on the 5th and the 1st to 4th is in week one<br>
This field can be used with any calendar system.
In the resolving phase of parsing, a date can be created from a year, week-of-month, month-of-year and day-of-week.
In ResolverStyle#STRICT strict mode, all four fields are validated against their range of valid values. The week-of-month field is validated to ensure that the resulting month is the month requested.
In ResolverStyle#SMART smart mode, all four fields are validated against their range of valid values. The week-of-month field is validated from 0 to 6, meaning that the resulting date can be in a different month to that specified.
In ResolverStyle#LENIENT lenient mode, the year and day-of-week are validated against the range of valid values. The resulting date is calculated equivalent to the following four stage approach. First, create a date on the first day of the first week of January in the requested year. Then take the month-of-year, subtract one, and add the amount in months to the date. Then take the week-of-month, subtract one, and add the amount in weeks to the date. Finally, adjust to the correct day-of-week within the localized week.
