Compute the day count between 2 dates.

A DayCount is a length of time expressed in years (can also be expressed in days depending on the DayCount Code).

For the 'dayCounter' parameter, please refer to the large number of enumeration functions present within the CapeTools Enums category of functions.

The CapeTools Enums category of functions return correct string codes that can be passed to parameters taking fixed string values defined by the library (ie - DayCount codes, frequency codes, currency codes, compounding codes, business day convention codes etc...).

You can thus execute these enumeration functions which return the proper code, instead of trying to remember the string code needed or making spelling mistakes which can be difficult to debug.

Double CTCalendars.DayCount( _
DayCountEnum dayCounter, _
Long StartDate, _
Long EndDate)

=CT.DTE.DayCount(
Excel String Cell dayCounter,
Excel Numeric Cell StartDate,
Excel Numeric Cell EndDate)

static double DayCount(
DayCountEnum dayCounter,
long StartDate,
long EndDate);

System.Double CTCalendarsSA.DayCount(
CTIEnums.DayCountEnum dayCounter,
System.Int32 StartDate,
System.Int32 EndDate);

The C# example below contains all the sub-function calls leading up to this function call. As a result, the example can contain a lot of code.

The VB.NET, J#, C++.NET, Java, Excel VBA, Visual Basic 6 (via COM) and C++ examples below contain function code stubs for the calls leading up to this function call. However, the function call for this function is displayed.
You can easily reproduce the stub functions code from the C# example.
