The Get-Date cmdlet gets a DateTime object that represents the current date or a date that you specify. Get-Date can format the date and time in several .NET and UNIX formats. You can use Get-Date to generate a date or time character string, and then send the string to other cmdlets or programs.

Get-Date uses the computer's culture settings to determine how the output is formatted. To view your computer's settings, use (Get-Culture).DateTimeFormat.

In this example, Get-Date displays the current system date and time. The output is in the long-date and long-time formats.

This example shows how to use Get-Date to get either the date or time element. The parameter uses the arguments Date, Time, or DateTime.

Get-Date -DisplayHint Date

Tuesday, June 25, 2019

Get-Date uses the DisplayHint parameter with the Date argument to get only the date.

In this example, a .NET format specifier is used to customize the output's format. The output is a String object.

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

Tuesday 06/25/2019 16:17 -07:00

Get-Date uses the Format parameter to specify several format specifiers.

The .NET format specifiers used in this example are defined as follows:

For more information about .NET format specifiers, see Custom date and time format strings.

In this example, several UFormat format specifiers are used to customize the output's format. The output is a String object.

Get-Date -UFormat "%A %m/%d/%Y %R %Z"

Tuesday 06/25/2019 16:19 -07

Get-Date uses the UFormat parameter to specify several format specifiers.

The UFormat format specifiers used in this example are defined as follows:

For a list of valid UFormat format specifiers, see the Notes section.

In this example, a property is used to get the numeric day of the year.

The Gregorian calendar has 365 days, except for leap years that have 366 days. For example, December 31, 2020 is day 366.

(Get-Date -Year 2020 -Month 12 -Day 31).DayOfYear

366

Get-Date uses three parameters to specify the date: Year, Month, and Day. The command is wrapped with parentheses so that the result is evaluated by the DayofYear property.

This example uses a boolean method to verify if a date is adjusted by daylight savings time.

$DST = Get-Date
$DST.IsDaylightSavingTime()

True

A variable, $DST stores the result of Get-Date. $DST uses the IsDaylightSavingTime method to test if the date is adjusted for daylight savings time.

In this example, the current time is converted to UTC time. The UTC offset for the system's locale is used to convert the time. A table in the Notes section lists the valid UFormat format specifiers.

Get-Date -UFormat "%A %B/%d/%Y %T %Z"
$Time = Get-Date
$Time.ToUniversalTime()

Wednesday June/26/2019 10:45:26 -07

Wednesday, June 26, 2019 17:45:26

Get-Date uses the UFormat parameter with format specifiers to display the current system date and time. The format specifier %Z represents the UTC offset of -07.

The $Time variable stores the current system date and time. $Time uses the ToUniversalTime() method to convert the time based on the computer's UTC offset.

In this example, a format specifier creates a timestamp String object for a directory name. The timestamp includes the date, time, and UTC offset.

$timestamp = Get-Date -Format o | ForEach-Object { $_ -replace ":", "." }
New-Item -Path C:\Test\$timestamp -Type Directory

    Directory: C:\Test

Mode                LastWriteTime         Length Name
----                -------------         ------ ----
d-----         6/27/2019    07:59                2019-06-27T07.59.24.4603750-07.00

The $timestamp variable stores the results of a Get-Date command. Get-Date uses the Format parameter with the format specifier of lowercase o to create a timestamp String object. The object is sent down the pipeline to ForEach-Object. A ScriptBlock contains the $_ variable that represents the current pipeline object. The timestamp string is delimited by colons that are replaced by periods.

New-Item uses the Path parameter to specify the location for a new directory. The path includes the $timestamp variable as the directory name. The Type parameter specifies that a directory is created.

This cmdlet supports the common parameters: -Debug, -ErrorAction, -ErrorVariable, -InformationAction, -InformationVariable, -OutBuffer, -OutVariable, -PipelineVariable, -ProgressAction, -Verbose, -WarningAction, and -WarningVariable. For more information, see about_CommonParameters.

Get-Date accepts pipeline input. For example, Get-ChildItem | Get-Date.

Get-Date returns a DateTime object except when the Format and UFormat parameters are used. The Format or UFormat parameters return String objects.

When a DateTime object is sent down the pipeline to a cmdlet such as Add-Content that expects string input, PowerShell converts the object to a String object.

The method (Get-Date).ToString() converts a DateTime object a String object.

To display an object's properties and methods, send the object down the pipeline to Get-Member. For example, Get-Date | Get-Member.

DateTime objects are in long-date and long-time formats for the system locale.

The valid UFormat specifiers are displayed in the following table:
