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:
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.
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);
