Examples of org.jfree.data.time.Week

org.jfree.data.time.Week
A calendar week. All years are considered to have 53 weeks, numbered from 1 to 53, although in many cases the 53rd week is empty. Most of the time, the 1st week of the year *begins* in the previous calendar year, but it always finishes in the current year (this behaviour matches the workings of the GregorianCalendar class).
This class is immutable, which is a requirement for all {@link RegularTimePeriod} subclasses.

     *
     * In London and Paris, Monday is the first day of the week, while in the
     * US it is Sunday.
