A day-of-week, such as 'Tuesday'. !(p) {@code DayOfWeek} is an enum representing the 7 days of the week - Monday, Tuesday, Wednesday, Thursday, Friday, Saturday and Sunday. !(p) In addition to the textual enum name, each day-of-week has an {@code int} value. The {@code int} value follows the ISO-8601 standard, from 1 (Monday) to 7 (Sunday). It is recommended that applications use the enum rather than the {@code int} value to ensure code clarity. !(p) This enum provides access to the localized textual form of the day-of-week. Some locales also assign different numeric values to the days, declaring Sunday to have the value 1, however this class provides no support for this. See {@link WeekFields} for localized week-numbering. !(p) !(b)Do not use {@code ordinal()} to obtain the numeric representation of {@code DayOfWeek}. Use {@code getValue()} instead.</b> !(p) This enum represents a common concept that is found _in many calendar systems. As such, this enum may be used by any calendar system that has the day-of-week concept defined exactly equivalent to the ISO calendar system.
