daysact

Actual number of days between dates

Syntax

NumDays = daysact(StartDate, EndDate)

Arguments

Either input can contain multiple values, but if so, the other 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 = daysact(StartDate, EndDate) returns the actual number of days between two dates. Enter dates as serial date numbers or date strings. NumDays is negative if EndDate is earlier than StartDate.

NumDays = daysact(StartDate) returns the actual number of days between the MATLAB^® base date and StartDate. In MATLAB software, the base date 1 is 1-Jan-0000 A.D. See datenum for a similar function.

Examples

NumDays = daysact('7-sep-2002',  '25-dec-2002')
NumDays =
   109

NumDays = daysact('9/7/2002')
NumDays =
      731466

MoreDays = ['09/07/2002'; '10/22/2002'; '11/05/2002'];
NumDays = daysact(MoreDays, '12/25/2002')
NumDays =
   109
    64
    50
