A date in the International fixed calendar system.

Implements a pure International Fixed calendar (also known as the Cotsworth plan, the Eastman plan, the 13 Month calendar or the Equal Month calendar) a solar calendar proposal for calendar reform designed by Moses B. Cotsworth, who presented it in 1902.

It provides for a year of 13 months of 28 days each. Month 6 has 29 days in a leap year, but the additional day is not part of any week. Month 12 always has 29 days, but the additional day is not part of any week. It is therefore a perennial calendar, with every date fixed always on the same weekday. Though it was never officially adopted in any country, it was the official calendar of the Eastman Kodak Company from 1928 to 1989.

This date operates using the International fixed calendar. This calendar system is a proposed reform calendar system, and is not in common use. The International fixed differs from the Gregorian in terms of month count and length, and the leap year rule. Dates are aligned such that 0001/01/01 (International fixed) is 0001-01-01 (ISO).

More information is available in the International Fixed Calendar Wikipedia article.

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 ==.

public InternationalFixedDate minus(TemporalAmount amount)

Overrides default java.time.chrono.ChronoLocalDate.minus.

Doc from java.time.chrono.ChronoLocalDate.minus.

Returns an object of the same type as this object with an amount subtracted.

This adjusts this temporal, subtracting according to the rules of the specified amount. The amount is typically a java.time.Period but may be any other type implementing the TemporalAmount interface, such as java.time.Duration.

Some example code indicating how and why this method is used:

 date = date.minus(period);               // subtract a Period instance
 date = date.minus(duration);             // subtract a Duration instance
 date = date.minus(workingDays(6));       // example user-written workingDays method

Note that calling plus followed by minus is not guaranteed to return the same date-time.

Parameters
amount:TemporalAmount

Doc from java.time.temporal.Temporal.minus.

the amount to subtract, not null

Returns:InternationalFixedDate

Doc from java.time.temporal.Temporal.minus.

an object of the same type with the specified adjustment made, not null

public InternationalFixedDate minus(long amountToSubtract, TemporalUnit unit)

Overrides default java.time.chrono.ChronoLocalDate.minus.

Doc from java.time.chrono.ChronoLocalDate.minus.

Returns an object of the same type as this object with the specified period subtracted.

This method returns a new object based on this one with the specified period subtracted. For example, on a LocalDate, this could be used to subtract a number of years, months or days. The returned object will have the same observable type as this object.

In some cases, changing a field is not fully defined. For example, if the target object is a date representing the 31st March, then subtracting one month would be unclear. In cases like this, the field is responsible for resolving the result. Typically it will choose the previous valid date, which would be the last valid day of February in this example.

Parameters
amountToSubtract:long

Doc from java.time.temporal.Temporal.minus.

the amount of the specified unit to subtract, may be negative

unit:TemporalUnit

Doc from java.time.temporal.Temporal.minus.

the unit of the amount to subtract, not null

public InternationalFixedDate plus(TemporalAmount amount)

Overrides default java.time.chrono.ChronoLocalDate.plus.

Doc from java.time.chrono.ChronoLocalDate.plus.

Returns an object of the same type as this object with an amount added.

This adjusts this temporal, adding according to the rules of the specified amount. The amount is typically a java.time.Period but may be any other type implementing the TemporalAmount interface, such as java.time.Duration.

Some example code indicating how and why this method is used:

 date = date.plus(period);                // add a Period instance
 date = date.plus(duration);              // add a Duration instance
 date = date.plus(workingDays(6));        // example user-written workingDays method

Note that calling plus followed by minus is not guaranteed to return the same date-time.

Parameters

Overrides default java.time.chrono.ChronoLocalDate.plus.

Doc from java.time.chrono.ChronoLocalDate.plus.

Returns an object of the same type as this object with the specified period added.

This method returns a new object based on this one with the specified period added. For example, on a LocalDate, this could be used to add a number of years, months or days. The returned object will have the same observable type as this object.

In some cases, changing a field is not fully defined. For example, if the target object is a date representing the 31st January, then adding one month would be unclear. In cases like this, the field is responsible for resolving the result. Typically it will choose the previous valid date, which would be the last valid day of February in this example.

Parameters

Gets the range of valid values for the specified field.

All fields can be expressed as a long integer. This method returns an object that describes the valid range for that value. The value of this temporal object is used to enhance the accuracy of the returned range. If the date-time cannot return the range, because the field is unsupported or for some other reason, an exception will be thrown.

Note that the result only describes the minimum and maximum valid values and it is important not to read too much into them. For example, there could be values within the range that are invalid for the field.

private static InternationalFixedDate resolvePreviousValid(int prolepticYear, int month, int day)

Consistency check for dates manipulations after calls to plus(long, TemporalUnit), minus(long, TemporalUnit), until(AbstractDate, TemporalUnit) or with(TemporalField, long).

Parameters
prolepticYear:int

the International fixed proleptic-year

month:int

the International fixed month, from 1 to 13

day:int

the International fixed day-of-month, from 1 to 28 (29 for Leap Day or Year Day)

Returns:InternationalFixedDate

the resolved date

public long toEpochDay()

Overrides default java.time.chrono.ChronoLocalDate.toEpochDay.

Doc from java.time.chrono.ChronoLocalDate.toEpochDay.

Converts this date to the Epoch Day.

The Epoch Day count is a simple incrementing count of days where day 0 is 1970-01-01 (ISO). This definition is the same for all chronologies, enabling conversion.

This default implementation queries the EPOCH_DAY field.

Returns:long

the Epoch Day equivalent to this date

public long until(Temporal endExclusive, TemporalUnit unit)

Implements java.time.chrono.ChronoLocalDate.until.

Doc from java.time.chrono.ChronoLocalDate.until.

Calculates the amount of time until another date in terms of the specified unit.

This calculates the amount of time between two ChronoLocalDate objects in terms of a single TemporalUnit. The start and end points are this and the specified date. The result will be negative if the end is before the start. The Temporal passed to this method is converted to a ChronoLocalDate using Chronology#date(TemporalAccessor). The calculation returns a whole number, representing the number of complete units between the two dates. For example, the amount in days between two dates can be calculated using startDate.until(endDate, DAYS).

There are two equivalent ways of using this method. The first is to invoke this method. The second is to use TemporalUnit#between(Temporal, Temporal):

  // these two lines are equivalent
  amount = start.until(end, MONTHS);
  amount = MONTHS.between(start, end);
The choice should be made based on which makes the code more readable.

The calculation is implemented in this method for ChronoUnit. The units DAYS, WEEKS, MONTHS, YEARS, DECADES, CENTURIES, MILLENNIA and ERAS should be supported by all implementations. Other ChronoUnit values will throw an exception.

If the unit is not a ChronoUnit, then the result of this method is obtained by invoking TemporalUnit.between(Temporal, Temporal) passing this as the first argument and the converted input temporal as the second argument.

This instance is immutable and unaffected by this method call.

Parameters
endExclusive:Temporal

the end date, exclusive, which is converted to a ChronoLocalDate in the same chronology, not null

unit:TemporalUnit

the unit to measure the amount in, not null

Returns:long

the amount of time between this date and the end date

public ChronoPeriod until(ChronoLocalDate endDateExclusive)

Implements java.time.chrono.ChronoLocalDate.until.

Doc from java.time.chrono.ChronoLocalDate.until.

Calculates the period between this date and another date as a ChronoPeriod.

This calculates the period between two dates. All supplied chronologies calculate the period using years, months and days, however the ChronoPeriod API allows the period to be represented using other units.

The start and end points are this and the specified date. The result will be negative if the end is before the start. The negative sign will be the same in each of year, month and day.

The calculation is performed using the chronology of this date. If necessary, the input date will be converted to match.

This instance is immutable and unaffected by this method call.

Parameters
endDateExclusive:ChronoLocalDate

the end date, exclusive, which may be in any chronology, not null

Returns:ChronoPeriod

the period between this date and the end date, not null

public InternationalFixedDate with(TemporalAdjuster adjuster)

Overrides default java.time.chrono.ChronoLocalDate.with.

Doc from java.time.chrono.ChronoLocalDate.with.

Returns an adjusted object of the same type as this object with the adjustment made.

This adjusts this date-time according to the rules of the specified adjuster. A simple adjuster might simply set the one of the fields, such as the year field. A more complex adjuster might set the date to the last day of the month. A selection of common adjustments is provided in TemporalAdjusters. These include finding the "last day of the month" and "next Wednesday". The adjuster is responsible for handling special cases, such as the varying lengths of month and leap years.

Some example code indicating how and why this method is used:

 date = date.with(Month.JULY);        // most key classes implement TemporalAdjuster
 date = date.with(lastDayOfMonth());  // static import from Adjusters
 date = date.with(next(WEDNESDAY));   // static import from Adjusters and DayOfWeek
Parameters
adjuster:TemporalAdjuster

Doc from java.time.temporal.Temporal.with.

the adjuster to use, not null

Returns:InternationalFixedDate

Doc from java.time.temporal.Temporal.with.

an object of the same type with the specified adjustment made, not null

public InternationalFixedDate with(TemporalField field, long newValue)

Overrides org.threeten.extra.chrono.AbstractDate.with.

Overrides default java.time.chrono.ChronoLocalDate.with.

Doc from java.time.chrono.ChronoLocalDate.with.

Returns an object of the same type as this object with the specified field altered.

This returns a new object based on this one with the value for the specified field changed. For example, on a LocalDate, this could be used to set the year, month or day-of-month. The returned object will have the same observable type as this object.

In some cases, changing a field is not fully defined. For example, if the target object is a date representing the 31st January, then changing the month to February would be unclear. In cases like this, the field is responsible for resolving the result. Typically it will choose the previous valid date, which would be the last valid day of February in this example.

Parameters
field:TemporalField

Doc from java.time.temporal.Temporal.with.

the field to set in the result, not null

newValue:long

Doc from java.time.temporal.Temporal.with.

the new value of the field in the result

Returns:InternationalFixedDate

Doc from java.time.temporal.Temporal.with.

an object of the same type with the specified field set, not null
