* {@code MonthDay} is an immutable date-time object that represents the combination * of a month and day-of-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 {@code MonthDay}. *
* Since a {@code 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, {@code MonthDay} only provides access to query and set the fields * {@code MONTH_OF_YEAR} and {@code 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. *
* This is a value-based
* class; use of identity-sensitive operations (including reference equality
* ({@code ==}), identity hash code, or synchronization) on instances of
* {@code MonthDay} may have unpredictable results and should be avoided.
* The {@code equals} method should be used for comparisons.
* @implSpec This class is immutable and thread-safe.
* @since 1.8
