Many hospitals do. Not actually put together the surgery schedule until a day before, due to last minute cancellations and additions. Call your doctor's office to confirm the date of your surgery. The exact time to report may not be known until the evening before.
Confidential info. Be cautious with your information. Your friend is trying to help you, but operating rooms are highly confidential and much effort goes in to protecting patient privacy. Okay to call your surgeon for reassurance about your or time.
