Get Date and Time Using PowerShell

PowerShell can do many things, and, like any suitable programming language, it can do just about anything we want with date and time. Using the Windows PowerShell Get-Date cmdlet and other techniques, you can find today’s date, tomorrow’s date, format dates, etc.

This article will explain how we can get the current date and time and how the DateTime object works in PowerShell.

Get Date and Time in PowerShell

One of the ways to discover the current date and time with Windows PowerShell is using the Get-Date command. This cmdlet displays the current date and time.

By default, the Get-Date command looks like it only returns the current date and time, but, in reality, it’s producing a lot more information. To find this information, pipe the Format-List cmdlet output below.

Get-Date | Format-List


DisplayHint : DateTime
Date        : 08/03/2022 12:00:00 am
Day         : 8
DayOfWeek   : Wednesday
DayOfYear   : 68
Hour        : 20
Kind        : Local
Millisecond : 671
Minute      : 18
Month       : 3
Second      : 1
Ticks       : 637824538816714508
TimeOfDay   : 20:18:01.6714508
Year        : 2022
DateTime    : Wednesday, 9 March 2022 8:18:01 pm

You can also use the Get-Member command to find all the object properties by running the Get-Date | Get-Member command.

If we check the type of object Get-Date | Get-Member returns, you’ll notice a System.DateTime object type. This class exposes all of the properties and methods we see.

We can discover its object type by using the below command.




Once we see all available properties, we can reference them with dot(.) notation, as shown below.




Date Arithmetic Using DateTime Methods in PowerShell

The System.DateTime object that Get-Date returns have various methods you can invoke to add or remove chunks of time. For example, if we run Get-Date | Get-Member, we will see different techniques that start with Add.

Get-Date | Get-Member | Where {$_.Name -like "Add*"}


   TypeName: System.DateTime

Name            MemberType Definition
----            ---------- ----------
Add             Method     datetime Add(timespan value)
AddDays         Method     datetime AddDays(double value)
AddHours        Method     datetime AddHours(double value)
AddMilliseconds Method     datetime AddMilliseconds(double value)
AddMinutes      Method     datetime AddMinutes(double value)
AddMonths       Method     datetime AddMonths(int months)
AddSeconds      Method     datetime AddSeconds(double value)
AddTicks        Method     datetime AddTicks(long value)
AddYears        Method     datetime AddYears(int value)

You’ll see a few invoking these methods and their output in the following commands.

#Adding 8 days to the current date

#Adding 3 hours to the current time

#Adding five years to the current date

#Subtracting 7 days from the current date using a negative number.

Compare Dates in PowerShell

You can also compare dates using standard PowerShell operators. For example, PowerShell knows when a date is “less than” (earlier than) or “greater than” (later than) another date.

To compare dates, create two DateTime objects using Get-Date or perhaps by casting strings with [DateTime] and then using standard PowerShell operators like -lt or -gt. We can see a simple example of comparing dates below.

#Declaring the date
$Date1 = (Get-Date -Month 10 -Day 14 -Year 2021)
$Date2 = Get-Date
$Date1 -lt $Date2



Convert Strings to DateTime Object in PowerShell

To convert a string variable to a DateTime object, preface the string (or variable) with the [DateTime] data type. When we do this, Windows PowerShell tries to interpret the string as a date and time and then provide all of the properties and methods available on this object type.

$Date = "2020-09-07T13:35:08.4780000Z"

DateTime Methods in PowerShell

One way to manipulate how a DateTime object is displayed in the console is by using several methods on the DateTime object. The DateTime object has four methods to manipulate the formatting.

  1. ToLongDateString()
  2. ToShortDateString()
  3. ToLongTimeString()
  4. ToShortTimeString()

Let’s see an examples using the ToShortDateString() and ToShortTimeString() methods.

[DateTime]$Date = $Date
$date.ToShortDateString() + " " + $date.ToShortTimeString()

Format DateTime Objects in PowerShell

To change the date and time format of a DateTime object, use the Get-Date command to generate the object and the -Format parameter to change the layout. The -Format parameter accepts a string of characters, representing how a date/time string should look.

Get-Date -Format "dddd dd-MM-yyyy HH:mm K"
