Hi All,

Greetings for the day!!!

Today bit different article from Microsoft 365 / Azure / SharePoint but important one.

Background

Recently I got a chance to implement the PowerShell script in which I need to do some date-time calculations. So explored the Get-Date PowerShell CMDLET and hence the article.

In this article we will in depth discuss the Get-Date PowerShell CMDLET

print current date

PS C:> date
Wednesday, June 22, 2022 11:08:20 AM

Get-Date

• Details
  • The Get-Date CMDLET gets a DateTime object that represents the current date or a date that we specify
  • Get-Date CMDLET can format the date and time in several .NET and UNIX formats
  • Get-Date uses the computer’s culture settings to format the output date
  • We can use “Get-Culture” CMDLET to know the our computers date time settings

PS C:\> (Get-Culture).DateTimeFormat
