Nintendo released a book to celebrate the 25th anniversary of the Zelda series titled 'Hyrule Historia'. The book contains artwork, designs, and information. It also contains the hotly debated timeline of the series - except this time it's 100% official. In the early 2000s Nintendo of America released this timeline - complete with a warning that this was only their interpretation and the actual timeline remains open to debate. Translator Dan Owsen wanted to upload a draft but Nintendo Japan requested them to cancel the plan - as despite having an official plan in Japan they want to keep the speculation and theories running for the fandom.
The book is currently available in Japanese only however a fan translation has begun. The above image is a translated version of the official timeline provided in the book.
