Class DayCountConvention_30U_360

java.lang.Object
net.finmath.time.daycount.DayCountConvention_30U_360
All Implemented Interfaces:
Serializable, DayCountConvention
public class DayCountConvention_30U_360 extends Object implements DayCountConvention, Serializable
Calculates the day count using the US 30/360 adjusted method. The daycount is calculated via (endDateYear - startDateYear) * 360.0 + (endDateMonth - startDateMonth) * 30.0 + (endDateDay - startDateDay) where startDateDay and endDateDay are adjusted towards 30, when being larger than 30 or if isEndOfMonth, also if they fall on the last day of February. See 30/360 US definition for details. This day count convention is sometime called Bond basis.
  • The method getDaycount corresponds to the implementation of the "US method" of Excel function DAYS360, i.e., DAYS360(startDate,endDate,FALSE).
  • The method getDaycountFraction corresponds to the implementation of the "30U/360 method" of Excel function YEARFRAC, i.e., YEARFRAC(startDate,endDate,0).
