Hi, I'm Carl and welcome to Just Answer. Total bummer about losing your iPad! Have you tried restoring your new iPad from an iCloud Backup? By default, Apple gives you 5GB of Cloud Storage so that you can backup your device to the Cloud where it's safe and restore to an Apple device if it becomes lost, broken, or stolen. If you do have a backup, restoring it will also restore your Gmail Account and Calendar to the new iPad making CalenGoo much more easier to set back up.
