daysdif (Financial Toolbox)

daysdif
Days between dates for any day-count basis

Syntax

NumDays = daysdif(StartDate, EndDate, Basis)

Arguments

StartDate
Enter as serial date numbers or date strings.

EndDate
Enter as serial date numbers or date strings.

Basis
(Optional) Day-count basis: 0 = actual/actual (default), 1 = 30/360, 2 = actual/360, 3 = actual/365.

`StartDate`	Enter as serial date numbers or date strings.
`EndDate`	Enter as serial date numbers or date strings.
`Basis`	(Optional) Day-count basis: 0 = actual/actual (default), 1 = 30/360, 2 = actual/360, 3 = actual/365.

Any input argument can contain multiple values, but if so, the other inputs must contain the same number of values or a single value that applies to all. For example, if StartDate is an n-row character array of date strings, then EndDate must be an n-row character array of date strings or a single date. NumDays is then an n-by-1 vector of numbers.

Description
NumDays = daysdif(StartDate, EndDate, Basis) returns the number of days between dates StartDate and EndDate using the given day-count basis. Enter dates as serial date numbers or date strings.

This function is a helper function for the bond pricing and yield functions. It is designed to make the code more readable and to eliminate redundant calls within if statements.

Examples

NumDays = daysdif('3/1/99', '3/1/00', 1)
NumDays =
   360

MoreDays = ['3/1/2001'; '3/1/2002'; '3/1/2003']; 
NumDays = daysdif('3/1/98', MoreDays)
NumDays =
         1096
         1461
         1826
