The Anime Timeline attempts to reconcile the strange time set-up by the anime adaptation of the Toaru Majutsu no Index universe. Having events widely different from the novels, the anime exists as its own universe separate from the novels and manga, though that doesn't mean elements and characters cannot be reused in their parent mediums, as Toaru Majutsu no Index universe is extremely dynamic to changes. Different from the Unified Story Timeline, the complete Anime Timeline does not list dates unless specifically stated in the show itself. Past events are mentioned only in the episode they appear in and will not have its own section if the date is listed. Because of this, some events, especially those that are outside of the episode order, are simply conjectures on which position of the timeline they are. Audio dramas and videogames are not included, but the Toaru Majutsu to Kagaku no Ensemble which is connected with the animated universe, specifically that of the Toaru Majutsu no Index Movie is included, as its place and canonicity in the universe is concretely given.

This timeline can also be viewed as a guide on how to view the anime adaptation in a chronological manner.
