Description

daysDiff

Return the (signed) number of days between the specified beginDate and endDate according to the specified day‐count convention with the specified calendar providing the definition of business days. If beginDate <= endDate then the result is non‐negative. The behavior is undefined unless isSupported(convention), calendar.isInRange(beginDate), and calendar.isInRange(endDate). Note that reversing the order of beginDate and endDate negates the result and that the result is 0 when beginDate == endDate.

isSupported

Return true if the specified convention is valid for use in daysDiff and yearsDiff, and false otherwise.

yearsDiff

Return the (signed fractional) number of years between the specified beginDate and endDate according to the specified day‐count convention with the specified calendar providing the definition of business days. If beginDate <= endDate then the result is non‐negative. The behavior is undefined unless isSupported(convention), calendar.isInRange(beginDate), and calendar.isInRange(endDate). Note that reversing the order of beginDate and endDate negates the result; specifically, |yearsDiff(b, e, cal, c) + yearsDiff(e, b, cal, c)| <= 1.0e‐15 for all calendars cal, valid dates b and e, and day‐count conventions c.
