Class DayCountConvention_30E_360

java.lang.Object
net.finmath.time.daycount.DayCountConvention_30E_360
All Implemented Interfaces:
Serializable, DayCountConvention
public class DayCountConvention_30E_360 extends Object implements DayCountConvention, Serializable
Implementation of 30E/360 and 30E+/360. Calculates the day count of 30E/360 as (endDateYear - startDateYear) * 360.0 + (endDateMonth - startDateMonth) * 30.0 + (Math.min(endDateDay, 30.0) - Math.min(startDateDay, 30.0)) This day count convention is sometime called Eurobond basis or 30/360 ISMA. For 30E/360 we have that:
  • The method getDaycount corresponds to the implementation of the "European method" of Excel function DAYS360, i.e., DAYS360(startDate,endDate,TRUE).
  • The method getDaycountFraction corresponds to the implementation of the "30E/360 method" of Excel function YEARFRAC, i.e., YEARFRAC(startDate,endDate,4).
The day count of 30E+/360 is that of 30E/360 whenever endDateDay is ≤ 30, otherwise it is that of 30E/360 plus one.
