Reasons why purchase date = expiration date What are the possible cases?

When the user's purchase information was retrieved from Japan using the AppStoreServerAPI, I was able to obtain it with the status ‘1: The auto-renewable subscription is active.’, However, the expiry date in the Payload was the previous day. How can this be the case?

Example: when the purchase information was retrieved on 10/02/2025 at 21:00:00, the expiry date for status ‘1’ was ‘2025/02/09’.
