I would be lost without my calendar as well. Let’s work together to see what we can recover. When you say your Yahoo account, did you sign in from a computer to check and see what is on that calendar? If the information is available from the computer, we should be able to recover on the device. If it is not, then you would need to reach out to Yahoo support through their website.
