# days360e

Days between dates based on 360-day year (European)

## Syntax

``NumDays = days360e(StartDate,EndDate)``

## Description

example

````NumDays = days360e(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. This day count convention is used primarily in Europe. Under this convention, all months contain 30 days.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 character array of date character vectors, then `EndDate` must be an `N`-by-`1` vector of integers or a single integer. Determine the Number of Days Between Two Dates Given a Basis of 30/360 Based on European Convention`NumDays` is then an `N`-by-`1` vector of date numbers. ```

## Examples

collapse all

Determine the `NumDays` using date character vectors for `StartDate` and `EndDate` for the month of January.

```StartDate = '1-Jan-2002'; EndDate = '1-Feb-2002'; NumDays = days360e(StartDate, EndDate)```
```NumDays = 30 ```

Determine the `NumDays` in the month of January using a datetime array for `StartDate`.

`NumDays = days360e(datetime('1-Jan-2002','Locale','en_US'), '1-Feb-2002')`
```NumDays = 30 ```

Determine the `NumDays` using a vector for `EndDate`.

```MoreDays = ['15-mar-2000'; '15-apr-2000'; '15-jun-2000']; NumDays = days360e('15-jan-2000', MoreDays)```
```NumDays = 3×1 60 90 150 ```

## Input Arguments

collapse all

Start date, specified as a scalar or an `N`-by-`1` or `1`-by-`N` vector using serial date numbers, date character vectors, or datetime arrays.

Data Types: `double` | `char` | `datetime`

End date, specified as a scalar or an `N`-by-`1` or `1`-by-`N` vector using serial date numbers, date character vectors, or datetime arrays.

Data Types: `double` | `char` | `datetime`

## Output Arguments

collapse all

Number of days between two dates given a basis of 30/360 based on European convention, returned as a scalar or an `N`-by-`1` or `1`-by-`N` vector containing the number of days.

`NumDays` returns as a double for serial date number, date character vector, or datetime inputs for `StartDate` and `EndDate`.
