How can a global admin list all the shared calendars in the tenant?

I am a global admin and need to search for a calendar by name. Does Office 365 have this capability or do I have to write a PowerShell script to get all the data and filter it with a regex or something?

Thanks!

Nothing built-in, but easy to report on via PowerShell. Here's a sample script I wrote a while back: https://www.michev.info/Blog/Post/3676/office-365-permission-inventory-calendar-permissions-2

You could use the script below to check whether there exists non-default permissions and non-anonymous permissions on user calendar:

 $users = Get-Mailbox -ResultSize Unlimited -RecipientTypeDetails UserMailbox
    
 foreach($user in $users){
     $user = $user.PrimarySmtpAddress+":\calendar"
     if(Get-MailboxFolderPermission -Identity $user | where{$_.User -notlike "*Default*" -and $_.User -notlike "*Anonymous*"}){
         "`n"+ $user + ":"
         Get-MailboxFolderPermission -Identity $user | where{$_.User -notlike "*Default*" -and $_.User -notlike "*Anonymous*"}
     }
 }

If there exists such permission, you will get an output like below:
