public final class PaxDate extends Object implements java.time.chrono.ChronoLocalDate, Serializable
This date operates using the Pax calendar.
This calendar system is a proposed reform calendar system, and is not in common use.
The Pax differs from the Gregorian in terms of month count and length, and the leap year rule.
Dates are aligned such that 0001-01-01 (Pax) is 0000-12-31 (ISO).
More information is available in the Pax Calendar Wikipedia article.
This class must be treated as a value type. Do not synchronize, rely on the identity hash code or use the distinction between equals() and ==.

clone, finalize, getClass, notify, notifyAll, wait, wait, waitpublic static PaxDate now()
PaxDate from the system clock in the default time-zone.
This will query the system clock in the default
time-zone to obtain the current date.
Using this method will prevent the ability to use an alternate clock for testing because the clock is hard-coded.
public static PaxDate now(java.time.ZoneId zone)
PaxDate from the system clock in the specified time-zone.
This will query the system clock to obtain the current date.
Specifying the time-zone avoids dependence on the default time-zone.
Using this method will prevent the ability to use an alternate clock for testing because the clock is hard-coded.
zone - the zone ID to use, not nullpublic static PaxDate now(java.time.Clock clock)
PaxDate from the specified clock.
This will query the specified clock to obtain the current date - today. Using this method allows the use of an alternate clock for testing. The alternate clock may be introduced using dependency injection.
clock - the clock to use, not nulljava.time.DateTimeException - if the current date cannot be obtainedpublic static PaxDate of(int prolepticYear, int month, int dayOfMonth)
PaxDate representing a date in the Pax calendar
system from the proleptic-year, month-of-year and day-of-month fields.
This returns a PaxDate with the specified fields.
The day must be valid for the year and month, otherwise an exception will be thrown.

or if the day-of-month is invalid for the month-yearpublic static PaxDate from(java.time.temporal.TemporalAccessor temporal)
PaxDate from a temporal object.
This obtains a date in the Pax calendar system based on the specified temporal.
A TemporalAccessor represents an arbitrary set of date and time information,
which this factory converts to an instance of PaxDate.
The conversion typically uses the EPOCH_DAY
field, which is standardized across calendar systems.
This method matches the signature of the functional interface TemporalQuery
allowing it to be used as a query via method reference, PaxDate::from.

The Chronology represents the calendar system in use.
The era and other fields in ChronoField are defined by the chronology.
getChronology in interface java.time.chrono.ChronoLocalDatepublic PaxEra getEra()
The Pax calendar system has two eras, 'CE' and 'BCE',
defined by PaxEra.

This returns the length of the month in days. Month lengths do not match those of the ISO calendar system.

Compares this date with another ensuring that the date is the same.
Only objects of this concrete type are compared, other types return false.
To compare the dates of two TemporalAccessor instances, including dates
in two different chronologies, use ChronoField.EPOCH_DAY as a comparator.
