DateTime.Add(TimeSpan) Method (System) | Microsoft Learn

DateTime.Add(TimeSpan) Method Definition

Returns a new DateTime that adds the value of the specified TimeSpan to the value of this instance.

public:
 DateTime Add(TimeSpan value);

public DateTime Add(TimeSpan value);

member this.Add : TimeSpan -> DateTime

Public Function Add (value As TimeSpan) As DateTime

Parameters

value: TimeSpan

A positive or negative time interval.

Returns

An object whose value is the sum of the date and time represented by this instance and the time interval represented by value.

Exceptions Examples

The following example demonstrates the Add method. It calculates the day of the week that is 36 days (864 hours) from this moment.

// Calculate what day of the week is 36 days from this instant.
let today = DateTime.Now
let duration = TimeSpan(36, 0, 0, 0)
let answer = today.Add duration
printfn $"{answer:dddd}"

// Calculate what day of the week is 36 days from this instant.
System.DateTime today = System.DateTime.Now;
System.TimeSpan duration = new System.TimeSpan(36, 0, 0, 0);
System.DateTime answer = today.Add(duration);
System.Console.WriteLine("{0:dddd}", answer);

' Calculate what day of the week is 36 days from this instant.
Dim today As System.DateTime
Dim duration As System.TimeSpan
Dim answer As System.DateTime

today = System.DateTime.Now
duration = New System.TimeSpan(36, 0, 0, 0)
answer = today.Add(duration)

System.Console.WriteLine("{0:dddd}", answer)

Remarks

You can use the Add method to add more than one kind of time interval (days, hours, minutes, seconds, or milliseconds) in a single operation. This method's behavior is identical to that of the addition operator. The DateTime structure also supports specialized addition methods (such as AddDays, AddHours, and AddMinutes) for each time interval.

The Add method takes into account leap years and the number of days in a month when performing date arithmetic.

This method does not change the value of this DateTime. Instead, it returns a new DateTime whose value is the result of this operation. The Kind property of the new DateTime instance is the same as that of the current instance.
