    The main API for dates, times, instants, and durations.

    The main API for dates, times, instants, and durations.

    The classes defined here represent the principal date-time concepts, including instants, durations, dates, times, time-zones and periods. They are based on the ISO calendar system, which is the de facto world calendar following the proleptic Gregorian rules. All the classes are immutable and thread-safe.

    Each date time instance is composed of fields that are conveniently made available by the APIs. For lower level access to the fields refer to the org.threeten.bp.temporal package. Each class includes support for printing and parsing all manner of dates and times. Refer to the org.threeten.bp.format package for customization options.

    The org.threeten.bp.chrono package contains the calendar neutral API. This is intended for use by applications that need to use localized calendars. It is recommended that applications use the ISO-8601 dates and time classes from this package across system boundaries, such as to the database or across the network. The calendar neutral API should be reserved for interactions with users.

    Dates and Times

    org.threeten.bp.Instant is essentially a numeric timestamp. The current Instant can be retrieved from a org.threeten.bp.Clock. This is useful for logging and persistence of a point in time and has in the past been associated with storing the result from java.lang.System#currentTimeMillis().

    org.threeten.bp.LocalDate stores a date without a time. This stores a date like '2010-12-03' and could be used to store a birthday.

    org.threeten.bp.LocalTime stores a time without a date. This stores a time like '11:30' and could be used to store an opening or closing time.

    org.threeten.bp.LocalDateTime stores a date and time. This stores a date-time like '2010-12-03T11:30'.

    org.threeten.bp.OffsetTime stores a time and offset from UTC without a date. This stores a date like '11:30+01:00'. The ZoneOffset is of the form '+01:00'.

    org.threeten.bp.OffsetDateTime stores a date and time and offset from UTC. This stores a date-time like '2010-12-03T11:30+01:00'. This is sometimes found in XML messages and other forms of persistence, but contains less information than a full time-zone.

    org.threeten.bp.ZonedDateTime stores a date and time with a time-zone. This is useful if you want to perform accurate calculations of dates and times taking into account the org.threeten.bp.ZoneId, such as 'Europe/Paris'. Where possible, it is recommended to use a simpler class. The widespread use of time-zones tends to add considerable complexity to an application.

    Duration and Period

    Beyond dates and times, the API also allows the storage of period and durations of time. A org.threeten.bp.Duration is a simple measure of time along the time-line in nanoseconds. A org.threeten.bp.Period expresses an amount of time in units meaningful to humans, such as years or hours.

    Additional value types

    org.threeten.bp.Year stores a year on its own. This stores a single year in isolation, such as '2010'.

    org.threeten.bp.YearMonth stores a year and month without a day or time. This stores a year and month, such as '2010-12' and could be used for a credit card expiry.

    org.threeten.bp.MonthDay stores a month and day without a year or time. This stores a month and day-of-month, such as '--12-03' and could be used to store an annual event like a birthday without storing the year.

    org.threeten.bp.Month stores a month on its own. This stores a single month-of-year in isolation, such as 'DECEMBER'.

    org.threeten.bp.DayOfWeek stores a day-of-week on its own. This stores a single day-of-week in isolation, such as 'TUESDAY'.

    Support for calendar systems other than the default ISO.

    Support for calendar systems other than the default ISO.

    The main API is based around the calendar system defined in ISO-8601. This package provides support for alternate systems.

    The supported calendar systems includes:

    -Hijrah calendar -Japanese calendar -Minguo calendar -Thai Buddhist calendar

    It is intended that applications use the main API whenever possible, including code to read and write from a persistent data store, such as a database, and to send dates and times across a network. This package is then used at the user interface level to deal with localized input/output. See ChronoLocalDate for a full discussion of the issues.

    Example

    This example creates and uses a date in a non-ISO calendar system.

            // Print the Thai Buddhist date
        ChronoLocalDate now1 = ThaiBuddhistChronology.INSTANCE.now();
        int day = now1.get(ChronoField.DAY_OF_MONTH);
        int dow = now1.get(ChronoField.DAY_OF_WEEK);
        int month = now1.get(ChronoField.MONTH_OF_YEAR);
        int year = now1.get(ChronoField.YEAR);
        System.out.printf("  Today is %s %s %d-%s-%d%n", now1.getChronology().getId(),
                dow, day, month, year);

        // Enumerate the list of available calendars and print today for each
        Set<String> names = Chronology.getAvailableIds();
        for (String name : names) {
            Chronology<?> chrono = Chronology.of(name);
            ChronoLocalDate<?> date = chrono.now();
            System.out.printf("   %20s: %s%n", chrono.getId(), date.toString());
        }

        // Print today's date and the last day of the year for the Thai Buddhist Calendar.
        ChronoLocalDate first = now1
                .with(ChronoField.DAY_OF_MONTH, 1)
                .with(ChronoField.MONTH_OF_YEAR, 1);
        ChronoLocalDate last = first
                .plus(1, ChronoUnit.YEARS)
                .minus(1, ChronoUnit.DAYS);
        System.out.printf("  %s: 1st of year: %s; end of year: %s%n", last.getChronology().getId(),
                first, last);

final class MinguoChronology extends Chronology with Serializable

The Minguo calendar system.

This chronology defines the rules of the Minguo calendar system. This calendar system is primarily used in the Republic of China, often known as Taiwan. Dates are aligned such that 0001-01-01 (Minguo) is 1912-01-01 (ISO).

The fields are defined as follows:

  • era - There are two eras, the current 'Republic' (ROC) and the previous era (BEFORE_ROC).
  • year-of-era - The year-of-era for the current era increases uniformly from the epoch at year one. For the previous era the year increases from one as time goes backwards. The value for the current era is equal to the ISO proleptic-year minus 1911.
  • proleptic-year - The proleptic year is the same as the year-of-era for the current era. For the previous era, years have zero, then negative values. The value is equal to the ISO proleptic-year minus 1911.
  • month-of-year - The Minguo month-of-year exactly matches ISO.
  • day-of-month - The Minguo day-of-month exactly matches ISO.
  • day-of-year - The Minguo day-of-year exactly matches ISO.
  • leap-year - The Minguo leap-year pattern exactly matches ISO, such that the two calendars are never out of step.
Specification for implementors

This class is immutable and thread-safe.

    Creates the chronology era object from the numeric value.

    The era is, conceptually, the largest division of the time-line. Most calendar systems have a single epoch dividing the time-line into two eras. However, some have multiple eras, such as one for the reign of each leader. The exact meaning is determined by the chronology according to the following constraints.

    The era in use at 1970-01-01 must have the value 1. Later eras must have sequentially higher values. Earlier eras must have sequentially lower values. Each chronology must refer to an enum or similar singleton to provide the era values.

    This method returns the singleton era of the correct type for the specified era value.

    Obtains a period for this chronology based on years, months and days.

    This returns a period tied to this chronology using the specified years, months and days. All supplied chronologies use periods based on years, months and days, however the ChronoPeriod API allows the period to be represented using other units.

    The default implementation returns an implementation class suitable for most calendar systems. It is based solely on the three units. Normalization, addition and subtraction derive the number of months in a year from the #range(ChronoField). If the number of months within a year is fixed, then the calculation approach for addition, subtraction and normalization is slightly different.

    If implementing an unusual calendar system that is not based on years, months and days, or where you want direct control, then the ChronoPeriod interface must be directly implemented.

    The returned period is immutable and thread-safe.
