days360

Days between dates based on 360-day year

Syntax

NumDays = days360(StartDate, EndDate)

Arguments

StartDate

Enter as serial date numbers or date strings.

EndDate

Enter as serial date numbers or date strings.

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-by-1 vector of integers or a single integer. NumDays is then an n-by-1 vector of date numbers.

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.

Examples

NumDays = days360('15-jan-2000', '15-mar-2000')
NumDays =

    60
MoreDays = ['15-mar-2000'; '15-apr-2000'; '15-jun-2000'];
NumDays = days360('15-jan-2000', MoreDays)
NumDays =

    60
    90
   150
