Description

daysDiff

Return the (signed) number of days between the specified beginDate and endDate according to the ISMA 30/360 day‐count convention. If beginDate <= endDate, then the result is non‐negative. Note that reversing the order of beginDate and endDate negates the result.

yearsDiff

Return the (signed fractional) number of years between the specified beginDate and endDate according to the ISMA 30/360 day‐count convention. If beginDate <= endDate, then the result is non‐negative. Note that reversing the order of beginDate and endDate negates the result; specifically, |yearsDiff(b, e) + yearsDiff(e, b)| <= 1.0e‐15 for all dates b and e.
