PowerShell log filename with datetime issue-CodePudding

I am trying to create a log filename for today date time using powershell command

 $date = Get-Date
    $log = "D:\NewFolder\Logs\FixService$date.log"  
    "Write this text to log" >> $log

I am getting error as shown below , How to do this?

 out-file : The given path's format is not supported.
    At D:\NewFolder\somefile.ps1:5 char:1
      "Write this text to log" >> $log
      ~~~~~~~~~~~~~~~~~~~~~~~~~~~
          CategoryInfo          : OpenError: (:) [Out-File], NotSupportedException
          FullyQualifiedErrorId : FileOpenFailure,Microsoft.PowerShell.Commands.OutFileCommand

But this works without date in log file name

$date = Get-Date  
$log = "D:\Crowdstrike\Logs\FixService.log"   
"Write this to log" >> $log

What I am doing wrong?

Powershell uses ToString method to convert the value of the current DateTime object to its equivalent string representation using the specified format and the formatting conventions of the current culture. You can inspect your current culture by

[System.Globalization.CultureInfo]::CurrentCulture.Name

Or using Get-Culture Cmdlet. The issue here is that the resultant string contain the characters that are not allowed in filenames. So one solution is to use the format parameter of the get-date Cmdlet.

Get-Date -Format yyyyMMdd

$LogPath = "C:\Users"

$LogPathName = Join-Path -Path $LogPath -ChildPath "logToday-$(Get-Date -Format 'MM-dd-yyyy').log"
