We've had APs off and on for 20 years or so, and I don't recall being given an extra day - but I obviously could just be misremembering. But since around 2017, we've had them non-stop, through the pandemic, and don't remember the extra day. It got all mixed up over the pandemic with them extending things automatically by a number of months. We've also been in a mode of renewing, so perhaps any extra day was kind of lost in the mix for us.....
So, don't know what you tell you, but I believe your pass will be good for 365 days. Is not having 366 days in 2025 a deal breaker?
