The official timeline from Nintendo
So the timeline starts with the golden goddesses Nayru, Din, and Farore. The created the land of Hyrule then the first game on the normal time line ⬆️ is skyward sword. After a fight between the goddess Hylia and Demise for the triforce, the goddess Hylia sends the normal people up into the sky and reincarnates into the first Zelda. Then Link and Zelda defeat Demise with the help of the master sword. I really don't know what happens in minish cap and four swords. Link fights against a dude named Vatti. Then we get to Ocarina of Time. Now this is one of the most important game in the timeline. This is where the split happens. In OoT Link travels between time. Then this where the split kicks in at the end of the game. Link can maybe die to Ganon and he is able to obtain all the triforce pieces but gets sent to the sacred realm by the six sages. This then leads into the fallen timeline, an alternate universe if link does and Ganon is a pig. Now back to the actual timeline. In the ending and spoilers ahead Zelda sends link back to his childhood. This causes two twin timelines. One where link from OoT is reliving his childhood that he didn't have and one where without link as an adult, Ganon breaks free from his seal and the Three Golden Goddess flood Hyrule leaving only islands for people to live on. In the child timeline link goes to find his missing fairy but then goes to termina in the process and has to stop the moon from crashing on termina in three days. Then we go to twilight princess. In tp link gets turned into a wolf and has to save Hyrule from the twilight kingdom with the help of Midna. Back to the adult timeline. After the flood a toon link has to save Hyrule. Then it goes into the other two. And that's my terrible explanation on the Zelda timeline. If you want more information videos game theory and chase kip both on YouTube are great.
