Here's the breakdown:
* Naruto Shippuden was originally released weekly with new episodes. This was a common format for anime during its run.
* Boruto: Naruto Next Generations, the sequel to Shippuden, also follows a weekly release schedule.
However, new episodes are not always released on the same day every week. Some weeks might have a new episode, while others might have a recap episode or a special episode.
It's important to check your preferred streaming platform or anime news sites for the latest release schedules.
Perhaps you are thinking of a specific anime with a weekly release schedule, or you might have encountered a delay in new episodes.
