Your calculations seem correct based on the information provided. Itachi assassinated the Uchiha clan when he was 13, while Kakashi was 22 and Yamato is four years younger than Kakashi, meaning that Kakashi was 20 years old when Itachi joined Anbu. Yamato joined Kakashi's Anbu team for two years before Itachi joined, meaning that Yamato joined Team Ro when Kakashi was 18 and Yamato was 14 at that time.

based on your assumption that they met three years before Yamato joined Team Ro, Kakashi would have been 15 years old and Yamato would have been 11 years old when they first met. It's always great to see fans digging deep into the omegle.2yu.co details and timelines of their favorite shows and characters. Keep up the good work!
