To get the last day of a specified month in PowerShell, you can use the following code:

$month = Get-Date "2021-04-01" # Specify the month you want to get the last day for $lastDay = ([datetime]::ParseExact("$($month.Month)/1/$($month.Year)", 'M/d/yyyy', [System.Globalization.CultureInfo]::InvariantCulture)).AddMonths(1).AddDays(-1).Day Write-Output $lastDay

This code snippet will return the last day of the specified month. You can replace the Get-Date value with any other date within the month you want to target.

What is the difference between using Get-Culture and Get-Date to get the last day of a specified month in PowerShell?

The key difference between using Get-Culture and Get-Date to get the last day of a specified month in PowerShell is that Get-Culture provides information about the current culture settings of the operating system, while Get-Date is used to retrieve the current date and time.

To get the last day of a specified month using Get-Culture, you would need to extract the calendar information from the specified culture and then calculate the last day of the month. This can be a more complex and error-prone approach compared to using Get-Date.

On the other hand, using Get-Date to get the last day of a specified month is more straightforward. You can specify the desired month and year and then use the AddMonths and AddDays methods to navigate to the following month and the previous day to get the last day of the specified month.

In summary, while both methods can be used to get the last day of a specified month in PowerShell, using Get-Date is typically a simpler and more direct approach.

How to get last day of July in PowerShell?

You can get the last day of July using the following PowerShell script:

$lastDayOfJuly = Get-Date -Year (Get-Date).Year -Month 7 -Day 1 -Hour 0 -Minute 0 -Second 0 $lastDayOfJuly = $lastDayOfJuly.AddMonths(1).AddDays(-1)

Write-Output $lastDayOfJuly

This script will get the current year, set the month to July, and then find the last day of July by adding 1 month and subtracting 1 day.

How to get the last day of a specified month in PowerShell for a specific year?

You can use the following PowerShell script to get the last day of a specified month for a specific year:

$year = 2022 $month = 12

$lastDay = [datetime]::DaysInMonth($year, $month)

Write-Output "The last day of the month is: $lastDay"

Just replace the values of $year and $month with the desired year and month for which you want to get the last day. This script uses the [datetime]::DaysInMonth() method to get the number of days in the specified month, which corresponds to the last day of that month for the specified year.

How to format the output of the last day of a specified month in PowerShell?

To format the output of the last day of a specified month in PowerShell, you can use the following script:

$Month = 2 $Year = 2022 $LastDayOfMonth = Get-Date -Year $Year -Month $Month -Day 1 -Hour 0 -Minute 0 -Second 0 -Millisecond 0 | AddMonths 1 | AddDays -1

Write-Output $LastDayOfMonth.ToString("yyyy-MM-dd")

Replace the values of $Month and $Year with the desired month and year. This script will calculate the last day of the specified month and format the output as "YYYY-MM-DD".

How to get last day of March in PowerShell?

You can get the last day of March in PowerShell by using the following command:

[DateTime]::DaysInMonth((Get-Date).Year, 3)

This command uses the DaysInMonth method to get the number of days in the month of March for the current year, which will give you the last day of March.
