Is Sasuke older than Naruto?

Their birth dates and official ages

In the Naruto series, official sources confirm that Sasuke Uchiha was born on July 23rd, while Naruto Uzumaki was born on October 10th of the same year. This means that Sasuke is about 3 months and 17 days older than Naruto.

Both characters are born in the same year, making the difference in age minimal but still relevant in certain contexts, especially considering their dynamic and development throughout the series.

How their ages affect their rivalry

Throughout their early years at the Ninja Academy, Sasuke and Naruto were in the same class, which means they received training at the same time despite Sasuke being slightly older. This age gap contributed to their rivalry, as Sasuke was often portrayed as more skilled and mature in comparison to Naruto.

Even though Naruto was younger, he constantly sought to surpass Sasuke, leading to one of the most iconic rivalries in anime history. The age difference itself does not play a huge role in their power gap, but it does contribute to the perception of Sasuke being slightly ahead in terms of experience and growth, especially in their younger years.

Their ages at key moments in the series

Part 1 (Naruto)

At the beginning of the original Naruto series, both Sasuke and Naruto are officially 12 years old. However, due to Sasuke's birthdate being in July and Naruto's in October, there is always a slight difference of three months between them.

By the time they participate in the Chūnin Exams, they are still 12 but approaching 13. By the end of Part 1, Sasuke is the first to turn 13, and Naruto follows three months later.
