Syntax

NumDays = days360(StartDate,EndDate)

Description

NumDays = days360(StartDate,EndDate) returns the number of days between StartDate and EndDate based on a 360-day year (that is, all months contain 30 days). If EndDate is earlier than StartDate, NumDays is negative.

Either input argument 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 datetime, then EndDate must be an N-by-1 vector of integers or a single integer. NumDays is then an N-by-1 vector of date numbers.

Determine the NumDays using a datetime for StartDate and EndDate. 

NumDays = days360(datetime(2000,1,15) , datetime(2000,3,15))
NumDays = 
60

Determine the NumDays using a datetime array for EndDate. 

MoreDays = [datetime(2000,3,15) ; datetime(2000,4,15) ; datetime(2000,6,15)];
NumDays = days360(datetime(2000,1,15), MoreDays)
NumDays = 3×1

Start date, specified as a scalar or an N-by-1 or 1-by-N vector using a datetime array, string array, or date character vectors.

To support existing code, days360 also accepts serial date numbers as inputs, but they are not recommended.
