Class PersianDate

Extends IDate.
Construct a new Persian astronomical date object. The constructor parameters can contain any of the following properties:

unixtime - sets the time of this instance according to the given unix time. Unix time is the number of milliseconds since midnight on Jan 1, 1970, Gregorian
julianday - sets the time of this instance according to the given Julian Day instance or the Julian Day given as a float
year - any integer, including 0
month - 1 to 12, where 1 means Farvardin, 2 means Ordibehesht, etc.
day - 1 to 31
hour - 0 to 23. A formatter is used to display 12 hour clocks, but this representation is always done with an unambiguous 24 hour representation
minute - 0 to 59
second - 0 to 59
millisecond - 0 to 999
timezone - the TimeZone instance or time zone name as a string of this persian date. The date/time is kept in the local time. The time zone is used later if this date is formatted according to a different time zone and the difference has to be calculated, or when the date format has a time zone component in it.
locale - locale for this persian date. If the time zone is not given, it can be inferred from this locale. For locales that span multiple time zones, the one with the largest population is chosen as the one that represents the locale.
date - use the given intrinsic Javascript date to initialize this one.

If the constructor is called with another Persian date instance instead of a parameter block, the other instance acts as a parameter block and its settings are copied into the current instance.
If the constructor is called with no arguments at all or if none of the properties listed above from unixtime through millisecond are present, then the date components are filled in with the current date at the time of instantiation. Note that if you do not give the time zone when defaulting to the current time and the time zone for all of ilib was not set with ilib.setTimeZone(), then the time zone will default to UTC ("Universal Time, Coordinated" or "Greenwich Mean Time").
If any of the properties from year through millisecond are not specified in the params, it is assumed that they have the smallest possible value in the range for the property (zero or one).

Defined in: ilib-full-dyn.js.

BP dates are any date before Farvardin 1, 1 AP. In the proleptic Persian calendar, there is a year 0, so any years that are negative or zero are BP.

Returns:

{number} 1 if this date is in the common era, -1 if it is before the common era

{RataDie} newRd(params)

Return a new RD for this date type using the given params.
