When executing the job, the determination to generate a feed is done taking in consideration the date and time in UTC format. Depending on which time zone users set on their profile, the feed event may appear either ahead or behind their local time.
Take for example a user with their profile set to Central Standard time and having a birthday on August 15. Central Standard Time is UTC-6, meaning that this feed could be generated at 6:00 PM and would show up on the recent activities before midnight of the user's birthday.
This behavior is expected and in accordance with the product specification.
