How can you be sure it's the last day?

If you need to leave feedback for a transaction that is more than 90 days old, you may do so using the "single transaction form" link located on the Leave Feedback page. Remember, eBay only commits to items being available for 90 days, so if it is greater than 90 days you may not be able to leave feedback.
