public final class HybridDate extends Object implements ChronoLocalDate, Serializable
This date operates using the British Cutover calendar.
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 ==.

public static HybridDate now()
HybridDate
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 HybridDate now(ZoneId zone)
HybridDate
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 HybridDate now(Clock clock)
HybridDate
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 nullDateTimeException
- if the current date cannot be obtainedpublic static HybridDate of(int prolepticYear, int month, int dayOfMonth)
HybridDate
representing a date in the British Cutover calendar
system from the proleptic-year, month-of-year and day-of-month fields.
This returns a HybridDate
with the specified fields.
Dates in the middle of the cutover gap, such as the 10th September 1752, will not throw an exception. Instead, the date will be treated as a Julian date and converted to an ISO date, with the day of month shifted by 11 days.
Invalid dates, such as September 31st will throw an exception.
prolepticYear
- the British Cutover proleptic-yearmonth
- the British Cutover month-of-year, from 1 to 12dayOfMonth
- the British Cutover day-of-month, from 1 to 31DateTimeException
- if the value of any field is out of range,
or if the day-of-month is invalid for the month-yearpublic static HybridDate from(TemporalAccessor temporal)
HybridDate
from a temporal object.
This obtains a date in the British Cutover 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 HybridDate
.
The conversion 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, HybridDate::from
.

public HybridChronology getChronology()
The Chronology
represents the calendar system in use.
The era and other fields in ChronoField
are defined by the chronology.
getChronology
in interface ChronoLocalDate
public JulianEra getEra()
The British Cutover calendar system has two eras, 'AD' and 'BC',
defined by JulianEra
.
getEra
in interface ChronoLocalDate
public int lengthOfMonth()
This returns the length of the month in days. This takes into account the cutover, returning 19 in September 1752.
lengthOfMonth
in interface ChronoLocalDate
public int lengthOfYear()
This returns the length of the year in days. This takes into account the cutover, returning 355 in 1752.
