# DateTimeOffset.AddMinutes(Double) Method

## Definition

Returns a new DateTimeOffset object that adds a specified number of whole and fractional minutes to the value of this instance.

```
public:
DateTimeOffset AddMinutes(double minutes);
```

`public DateTimeOffset AddMinutes (double minutes);`

`member this.AddMinutes : double -> DateTimeOffset`

`Public Function AddMinutes (minutes As Double) As DateTimeOffset`

#### Parameters

- minutes
- Double

A number of whole and fractional minutes. The number can be negative or positive.

#### Returns

An object whose value is the sum of the date and time represented by the current DateTimeOffset object and the number of minutes represented by `minutes`

.

#### Exceptions

The resulting DateTimeOffset value is less than MinValue.

-or-

The resulting DateTimeOffset value is greater than MaxValue.

## Remarks

The fractional part of the `minutes`

parameter is the fractional part of a minute. For example, 4.5 is equivalent to 4 minutes, 30 seconds, 0 milliseconds. The `minutes`

parameter is rounded to the nearest millisecond.

Note

This method returns a new DateTimeOffset object. It does not modify the value of the current object by adding `minutes`

to its date and time.

Because a DateTimeOffset object does not represent the date and time in a specific time zone, the AddMinutes method does not consider a particular time zone's adjustment rules when it performs date and time arithmetic.

Converting time intervals of less than a minute to a fraction can involve a loss of precision. (For example, one second is 0.01666 of a minute.) If this is problematic, you can use the Add method, which enables you to specify more than one kind of time interval in a single method call and eliminates the need to convert time intervals to fractional parts of a minute.
