Thank you for your interest in this new feature! Right now, the calendar feature is in beta and is not yet available to be added to your account. We are very excited to announce that we've had a lot of positive feedback about the calendar feature and will be moving forward with continued development so that all of our customers can utilize it. As soon as this feature is ready, we will make sure to let our customers know here in the Community, in the Notifications Center, and within the KnowledgeBase.
You are welcome! I'm really looking forward to the calendar feature as well.
