I am having Sitecore's Date field data coming as 20230804T000000Z, I also have time coming as 11 am. The Date is coming from Sitecore date field, and time from Single-Line Text field as below.

enter image description here

I need to combine these two and get the date and time as this format 2023-08-04T03:02:36+00:00 I got the date and time in my PowerShell using

$field_date_range_start_date = $item.Fields["Event Start Date"]
$field_date_range_start_time =$item.Fields["Event Start Time"]

have tried using

  1. split() but out don't help out it says this is not supported

  2. something like

    $year = $dateString.Substring(0, 4)
    $month = $dateString.Substring(4, 2)
    $day = $dateString.Substring(6, 2)

and concat these to get yyyy-MM-dd format but didn't work out it says Substring() is not supported

  1. ToString("yyyy-MM-dd") also didn't help work out it says this is not supported

  2. [DateTime]::ParseExact( $field_date_range_start_date, "yyyy-MM-dd", [System.Globalization.CultureInfo]::InvariantCulture) gives error in ParseExact

Is there anyway that I can achieve converting 20230804T000000Z to yyyy-MM-dd and combining with 11 am($field_date_range_start_time) and finally get my date variable to have format used in this sample 2023-08-04T03:02:36+00:00, using Sitecore PowerShell Script as I am exporting some of my data


  • You could have used date time field instead and then that would have returned the data in ISO format as you intend...

function Convert-DateFormat {
    $inputDate = [datetime]::ParseExact($inputDateString, "yyyyMMddTHHmmssZ", $null)
    $outputDateString = $inputDate.ToString("yyyy-MM-ddTHH:mm:sszzz")
    return $outputDateString

You can use this method to convert your date to the new format. You need to use also Sitecore powershell extension to update the fields

$item = Get-Item .
$item.Fields["YourDateFieldName"].Value =Convert-DateFormat($currentDateFieldName");

You can change the date format using Powershell using this way.

$homedate = Get-Item "/sitecore/content/Home/Sample"

$date2 = $homedate.Fields["date"].Value

$dateTime = ([sitecore.dateutil]::IsoDateToDateTime($homedate["date"]))

Write-Host $dateTime.ToString("yyyy-MM-dd")

It will give you the output like below.

And using the [string]::Concat($string1, $string2) you can combine them.

Hope this helps.


You could do something like this:

[Sitecore.Data.Fields.DateField] $dateField = $item.Fields["Event Start Date"]
$dateString = $dateField.DateTime.ToString("yyyy-MM-dd")
$timeString = $item["Event Start Time"]
$yourString = [string]::Format("{0}T{1}",$dateString, $timeString)

The format in the $yourString variable can be changed as you need.


You can use following helper to format date in powershell.

$date = $item.Fields["Date"].Value
$isoDate =  [Sitecore.DateUtil]::IsoDateToDateTime($date)
Write-Host ($isoDate.ToString("yyyy-MM-dd"))

This would return in the format as below.

enter image description here

Though I would recommend you to change the field type from date to datetime instead. Hope this helps.


Please use the below script

$field_date_range_start_date = $item.Fields["Event Start Date"]
$field_date_range_start_time =$item.Fields["Event Start Time"]
# Parse date and time
$date = [datetime]::ParseExact($field_date_range_start_date.Value, "yyyyMMddTHHmmssZ", $null)
$time = Get-Date -Date $field_date_range_start_time.Value -Format "HH:mm"
# Combine date and time
$combinedDateTime = $date.ToString("yyyy-MM-dd") + "T" + $time + "+00:00"
# Output the combined date and time
Write-Output $combinedDateTime

This will return like below

Hope this helps!
