One Piece: How old was Luffy when he set sail and became a pirate?

Monkey D. Luffy, the protagonist of Eiichiro Oda's One Piece manga, is known for his many epic adventures. He is one of the most famous anime characters in history, and his adventures are known and followed worldwide. We know that Luffy embarked on his adventures on July 22, 1997, when the first chapter of the manga was released. It's been almost 26 years since that moment, and Luffy is still very active and present in our lives. But how old was Luffy when he actually set sail? We know he's wanted to become a pirate since he was a child, but when did his journey begin? In this article, we'll tell you a little about Luffy's journey in the One Piece series and how old he was when it all began.
As Oda confirmed in SBS Volume 4, Monkey D. Luffy was 17 years old when he set sail from the East Blue to become a pirate. The youngest we've seen him was 7, still just a boy who wanted to become a pirate. Ten years later, he actually began his journey, and given that he's been at sea for about two years, we know he's 19 years old at this point in the series.
The rest of this article will focus on the timeline of Luffy's seafaring adventures. Determining the timeline of a manga series is usually quite difficult, but thanks to Oda and his work, we have some official information to work with. This article will contain many spoilers, so be careful if you're not fully up to date on the latest events in the series.
The thing to know is that manga timelines are often impossible to trace correctly.
A general problem with shonen manga, in general, is that they don't follow an actual timeline. Now, this wouldn't be a problem if the authors were more precise in determining their in-universe timelines, but since that's not the case, fans usually have a hard time pinpointing certain moments and determining when certain events took place (Naruto is infamously known as an example of this). One Piece is a work that doesn't really stray far from this formula, and even if we know the general idea of the timeline, a precise determination is basically impossible.
In-universe, we know that there are two timelines, and it's important to know that these two timelines only give a rough overview of events in the One Piece world. We know that Luffy has been at sea for about two and a half years, but this was obvious just by knowing that we had a two-year time jump in the series. Now that we've given you these general points, we can explore Luffy's journey.
Thanks to Oda and a timeline, we can easily determine Luffy's age.
Now, before we give you the answer, we have to go back and thank Reddit user adnaphsaka, who created a timeline of the One Piece series so you can see how the series progressed up to the start of the Onigashima raid. This is important so you understand how long Luffy has been at sea and how his age has changed over the course of the series. Here's the timeline:

As you can see, this is a very accurate timeline confirming that Luffy has been at sea for approximately two years and 134 days, or roughly two years and four months, based on the data collected. So, given this fact, we know that Luffy is now about two years older than he was at the beginning of his journey. Knowing that Luffy was 19 at the time, we can infer that he was 17 when he began his journey, and Oda actually confirmed this in SBS Volume 4, back in 1998, revealing the following:
Q: How old are Luffy, Zoro, Nami and Shanks?
One Piece FigureCome seeA: A lot of people have sent me questions regarding age. Like, a lot of people. I guess this must be the number one question everyone always thinks about. Well, I'll answer it now! Luffy is currently 17, Zoro is 19, and Nami is 18. Well, since we have no idea where Shanks is right now, I'll just answer how old he was supposed to be 10 years ago. In Luffy's village, he was 27. As for Usopp, he's 17, just like Luffy.
As you can see, Luffy was 17 years old when he began his journey, and this was confirmed by Oda himself. You can follow the progression of his journey in the timeline we provided above, and you'll see that it all adds up.
The youngest we saw him was seven years old, still a small child with a burning desire to become a pirate. Ten years later, that same child set out alone, hoping to assemble a pirate crew and become the Pirate King by finding Gol D. Roger's One Piece treasure. And the rest is history.
