java.lang.Object
- org.threeten.extra.chrono.EthiopicDate

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<java.time.chrono.ChronoLocalDate>, java.time.chrono.ChronoLocalDate, java.time.temporal.Temporal, java.time.temporal.TemporalAccessor, java.time.temporal.TemporalAdjuster
```
public final class EthiopicDate
extends java.lang.Object
implements java.time.chrono.ChronoLocalDate, java.io.Serializable
```
A date in the Ethiopic calendar system.
This date operates using the Ethiopic calendar. This calendar system is primarily used in Ethiopia. Dates are aligned such that 0001-01-01 (Ethiopic) is 0008-08-27 (ISO).
Implementation Requirements
This class is immutable and thread-safe.
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 ==.

- Method Detail
  - now
```
public static EthiopicDate now()
```
    Obtains the current EthiopicDate 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.
    
    Returns:
    
    the current date using the system clock and default time-zone, not null
  - now
```
public static EthiopicDate now(java.time.ZoneId zone)
```
    Obtains the current EthiopicDate 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.
    
    Parameters:
    
    zone - the zone ID to use, not null
    
    Returns:
    
    the current date using the system clock, not null
  - now
```
public static EthiopicDate now(java.time.Clock clock)
```
    Obtains the current EthiopicDate 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.
    
    Parameters:
    
    clock - the clock to use, not null
    
    Returns:
    
    the current date, not null
    
    Throws:
    
    java.time.DateTimeException - if the current date cannot be obtained
  - of
```
public static EthiopicDate of(int prolepticYear,
                              int month,
                              int dayOfMonth)
```
    Obtains a EthiopicDate representing a date in the Ethiopic calendar system from the proleptic-year, month-of-year and day-of-month fields.
    This returns a EthiopicDate with the specified fields. The day must be valid for the year and month, otherwise an exception will be thrown.
    
    Parameters:
    
    prolepticYear - the Ethiopic proleptic-year
    
    month - the Ethiopic month-of-year, from 1 to 13
    
    dayOfMonth - the Ethiopic day-of-month, from 1 to 30
    
    Returns:
    
    the date in Ethiopic calendar system, not null
    
    Throws:
    
    java.time.DateTimeException - if the value of any field is out of range, or if the day-of-month is invalid for the month-year
  - from
```
public static EthiopicDate from(java.time.temporal.TemporalAccessor temporal)
```
    Obtains a EthiopicDate from a temporal object.
    This obtains a date in the Ethiopic 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 EthiopicDate.
    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, EthiopicDate::from.
    
    Parameters:
    
    temporal - the temporal object to convert, not null
    
    Returns:
    
    the date in Ethiopic calendar system, not null
    
    Throws:
    
    java.time.DateTimeException - if unable to convert to a EthiopicDate
  - getChronology
```
public EthiopicChronology getChronology()
```
    Gets the chronology of this date, which is the Ethiopic calendar system.
    The Chronology represents the calendar system in use. The era and other fields in ChronoField are defined by the chronology.
    
    Specified by:
    
    getChronology in interface java.time.chrono.ChronoLocalDate
    
    Returns:
    
    the Ethiopic chronology, not null
  - getEra
```
public EthiopicEra getEra()
```
    Gets the era applicable at this date.
    The Ethiopic calendar system has two eras, 'INCARNATION' and 'BEFORE_INCARNATION', defined by EthiopicEra.
    
    Specified by:
    
    getEra in interface java.time.chrono.ChronoLocalDate
    
    Returns:
    
    the era applicable at this date, not null
