Method Detail
{number}
equivalentCycleYear(year)
Return the equivalent year in the 2820 year cycle that begins on
Far 1, 474. This particular cycle obeys the cycle-of-years formula
whereas the others do not specifically. This cycle can be used as
a proxy for other years outside of the cycle by shifting them into
the cycle.
- Parameters:
- {number} year
- year to find the equivalent cycle year for
- Returns:
- {number} the equivalent cycle year
{number}
getMonLength(month, year)
Return the number of days in a particular month in a particular year. This function
can return a different number for a month depending on the year because of things
like leap years.
- Parameters:
- {number} month
- the month for which the length is sought
- {number} year
- the year within which that month can be found
- Returns:
- {number} the number of days within the given month in the given year
{number}
getNumMonths(year)
Return the number of months in the given year. The number of months in a year varies
for some luni-solar calendars because in some years, an extra month is needed to extend the
days in a year to an entire solar year. The month is represented as a 1-based number
where 1=first month, 2=second month, etc.
- Parameters:
- {number} year
- a year for which the number of months is sought
- Returns:
- {number} The number of months in the given year
{string}
getType()

The year parameter may be given as a number, or as a PersAlgoDate object.
- Parameters:
- {number} year
- the year for which the leap year information is being sought
- Returns:
- {boolean} true if the given year is a leap year
<deprecated>

options.
- Parameters:
- {Object} options
