How to Get the First Day of Next Month in PowerShell?

If you’re working with dates in PowerShell, you might need to get the first day of the next month. As a PowerShell developer, you might meet this requirement. In this tutorial, explain several methods to get the first day of the next month using PowerShell with examples.

To get the first day of the next month in PowerShell, you can use the Get-Date cmdlet combined with the .AddMonths(1) method. First, calculate the current date plus one month using $nextMonth = (Get-Date).AddMonths(1), then create a new date object for the first day of that month with $firstDayNextMonth = Get-Date -Year $nextMonth.Year -Month $nextMonth.Month -Day 1. This will give you the first day of the next month efficiently.

The basic syntax to get the first day of the next month in PowerShell involves using the Get-Date cmdlet combined with the .AddMonths() method. Here’s a simple script:

$nextMonth = (Get-Date).AddMonths(1)
$firstDayNextMonth = Get-Date -Year $nextMonth.Year -Month $nextMonth.Month -Day 1

In this snippet, we first calculate the current date plus one month using .AddMonths(1). Then, we construct a new date object representing the first day of that month.

Now, let me show you three methods to achieve this.

Method 1: Using Get-Date and AddMonths

In PowerShell, you can use the AddMonths() method with Get-Date to get the first day of the next month.

Let me show you an example.

Example

$nextMonth = (Get-Date).AddMonths(1)
$firstDayNextMonth = Get-Date -Year $nextMonth.Year -Month $nextMonth.Month -Day 1
Write-Output $firstDayNextMonth

In this example, we first get the current date and add one month to it. Then, we create a new date object for the first day of the calculated month.

I executed the above PowerShell script, and you can see the exact output in the screenshot below:

Method 2: Custom Function

You can also create a custom function and reuse it in PowerShell.

Example

function Get-FirstDayOfNextMonth {
    $nextMonth = (Get-Date).AddMonths(1)
    return Get-Date -Year $nextMonth.Year -Month $nextMonth.Month -Day 1
}

$firstDay = Get-FirstDayOfNextMonth
Write-Output $firstDay

Here, we define a function Get-FirstDayOfNextMonth that encapsulates the logic for calculating the first day of the next month. This function can be called whenever needed.

Here is the exact output in the screenshot below:

Method 3: Using DateTime Object

Another approach to get the first day of the next month involves directly working with .NET DateTime objects.

Here is an example.

Example

$today = [datetime]::Now
$nextMonth = $today.AddMonths(1)
$firstDayNextMonth = New-Object datetime ($nextMonth.Year, $nextMonth.Month, 1)
Write-Output $firstDayNextMonth

In this method, we use the [datetime]::Now to get the current date and time, add one month, and then create a new DateTime object for the first day of the next month.

After executing the PowerShell script, the output is in the screenshot below.
