/**
|
* A month-day in the ISO-8601 calendar system, such as `--12-03`.
|
*
|
* {@link MonthDay} is an immutable date-time object that represents the combination
|
* of a year and month. Any field that can be derived from a month and day, such as
|
* quarter-of-year, can be obtained.
|
*
|
* This class does not store or represent a year, time or time-zone.
|
* For example, the value "December 3rd" can be stored in a {@link MonthDay}.
|
*
|
* Since a {@link MonthDay} does not possess a year, the leap day of
|
* February 29th is considered valid.
|
*
|
* This class implements {@link TemporalAccessor} rather than {@link Temporal}.
|
* This is because it is not possible to define whether February 29th is valid or not
|
* without external information, preventing the implementation of plus/minus.
|
* Related to this, {@link MonthDay} only provides access to query and set the fields
|
* {@link MONTH_OF_YEAR} and {@link DAY_OF_MONTH}.
|
*
|
* The ISO-8601 calendar system is the modern civil calendar system used today
|
* in most of the world. It is equivalent to the proleptic Gregorian calendar
|
* system, in which today's rules for leap years are applied for all time.
|
* For most applications written today, the ISO-8601 rules are entirely suitable.
|
* However, any application that makes use of historical dates, and requires them
|
* to be accurate will find the ISO-8601 approach unsuitable.
|
*
|
* ### Specification for implementors
|
*
|
* This class is immutable and thread-safe.
