how to add a local calendar on iPhone Calendar app in iOS 18.x or macOS 15.x
Whenever I try to add a new calendar account on iPhone or MacBook using iOS 18.x or macOS 15.x, it gives prompt to choose any of the cloud based accounts.
Is it possible to add a local device based calendar which is not connected to any cloud based account, and also include that local calendar in the iCloud backup taken from the apple device.
