Fans still consider Itachi Uchiha to be one of the strongest characters to have appeared in the Naruto franchise. However, as fans would know, his brother Sasuke wasn't far off in strength than him. This accounts for the fact that he later donned both the Mangekyo Sharingan and Rinnegan.
With the Uchiha siblings being quite close to each other in strength, it is quite normal for fans to wonder about their age difference. Given that Itachi seemed quite old when Sasuke was born, fans find it confusing to decipher their age difference. Thus, here we will take a look at the same.

Naruto: What is the age difference between Itachi and Sasuke?
Itachi Uchiha was five years older than Sasuke Uchiha. At age 5, he witnessed destruction and death during the Third Shinobi World War. Following that, he became Sasuke's older brother when he was 5 years old.
Years after, when Itachi was 13 years old, he, alongside Obito Uchiha, committed the Uchiha Massacre. At the time, Sasuke was 7 years old. While their age difference at the time looked six, that was only because Itachi's birthday had passed and Sasuke was yet to turn 8 years old.
Itachi's birthday was on June 9, while Sasuke's birthday was on July 23. This means that the Uchiha Massacre took place somewhere between the two dates.
Meanwhile, in Naruto Shippuden, Sasuke Uchiha was initially 16 years old but later turned 17 with time. This is further supported by the fact that the war concluded on October 10, which happens to be Naruto's 17th birthday. Given that Sasuke was born a few months prior to Naruto, it is evident that Sasuke had already reached the age of 17.
Regarding Itachi Uchiha, his life was cut short at the age of 21 when he passed away following his defeat by Sasuke in their climactic battle. Given that Sasuke was 17 years old by the end of the series, it means that Itachi passed away before June 9 of the same year. This is why he did not turn 22 in the series.
