US30360 class
The 30/360 (US) day count convention which specifies that the number of days in the Calculation Period or Compounding Period in respect of which payment is being made is divided by 360, calculated on a formula basis as follows:
Day Count Fraction = [[360 ∗ (YY2 − YY1)] + [30 ∗ (MM2 − MM1)] + (DD2 − DD1)] / 360
where:
 "Y1" is the year, expressed as a number, in which the first day of the Calculation or Compounding Period falls;
 "Y2" is the year, expressed as a number, in which the day immediately following the last day included in the Calculation Period or Compounding Period falls;
 "M1" is the calendar month, expressed as a number, in which the first day of the Calculation Period or Compounding Period falls;
 "M2" is the calendar month, expressed as a number, in which the day immediately following the last day included in the Calculation Period or Compounding Period falls;
 "D1" is the first calendar day, expressed as number, of the Calculation Period or Compounding Period, unless such number would be 31, in which case D1 will be 30; and
 "D2" is the calendar day, expressed as a number, immediately following the last day included in the Calculation Period or Compounding Period, unless such number would be 31 and D1 is greater than 29, in which case D2 will be 30.
This convention is also known as "Bond_Basis_30360", "30/360", "360/360" or "Bond Basis"
