@Deprecated public class PersianCalendar extends Calendar
PersianCalendar is a subclass of Calendar that
that implements the Persian calendar. It is used as the main civil
calendar in Iran and Afghanistan, and by Iranians and Afghans worldwide.
The Persian calendar is solar, and is similar to the Gregorian calendar in various ways, except its leap year rule, which is determined astronomically. The Persian year starts around the March equinox.
The modern Persian calendar (used in Iran since 1925 CE and in Afghanistan since 1957 CE), has the lengths of the months fixed. The first six months are 31 days each, the next five months are 30 days each, and the final month is 29 days in non-leap years and 30 days in leap ones. Historically, the lengths of the month differed in different years, but they were finally fixed at the times mentioned above. Partial information is available about the historical lengths.
The official rule for determination of the beginning of the Persian year is locale dependent, but at the same time, it has not specified a locale. Iranians around the world traditionally follow the calendar authorities of Iran, which haven't officially specified the locale. Some calendarists use some point in Tehran as the locale, while others have tried the more neutral 52.5 degrees east meridian. It is not clear which locale should be used for the Persian calendar of Afghanistan, but it is expected that for about one year in every twenty-four years, the Afghan calendar may become different from the Iranian one.
The exact locale to be used for the Iranian calendar starts to make a difference at around 2090 CE. The specific arithmetic method implemented here, commonly known as the 33-year cycle rule, matches the astronomical calendar at least for the whole period that the calendar has been both well-defined and official, from 1925 to around 2090 CE. The other commonly known algorithm, the 2820-year cycle, has been incorrectly designed to follow the tropical year instead of the spring equinoctial year, and fails to match the astronomical one as early as 2025 CE.
This class should not be subclassed.
PersianCalendar usually should be instantiated using
Calendar.getInstance(ULocale) passing in a
ULocale with the tag "@calendar=persian".
