How Old Is Everyone On Grey's Anatomy Now?

PHoto: Courtesy of ABC.
Hypothetically, it should be easy to figure out the ages of everyone on Grey’s Anatomy. The series began in 2005, and most people are about 26 years old when they start their medical residency. The story begins when heroine Meredith Grey (Ellen Pompeo) enters the first year of her residency program, so, she should be about 26 at that point and about 41 now, 15 seasons later, right? Wrong.
The timeline of Grey’s Anatomy is bonkers. Over the last 15 seasons — and 13-and-a-half years — the ABC drama has gone through its fair share of time jumps, flash forwards, and confusingly long “years.” For example, did you know the first three seasons of Grey’s Anatomy, which are, all together, 61 episodes of television, took place over a single calendar year? One measly year, countless breakups, hookups, and makeups over roughly 2,562 minutes of TV.
Then, there were time jumps during seasons 11 and 12 to deal with the death of Derek Shepard (Patrick Dempsey). And there’s the simple question of how long a pre-Grey's Meredith traveling through Europe and how much earlier that backpacking trip took place ahead of the three-season long “year” that is the start of Grey’s Anatomy. And the fact that people can’t decide if those three seasons represent 2004 into 2005 or 2006 into 2007 (in real life, the series starts in 2005, but season 3 wrapped in 2007). These people have gone through a lot!

Meredith Grey

Age: About 39-40

Meredith was described as about 32 years old in the original Grey’s pilot script — a fact often mentioned in the fandom as way to figure out the expert doctor’s age. But, that detail was never mentioned in the actual final product, so we can ignore that fascinating, but not exactly applicable, tidbit.

Instead, let’s pay attention to facts that actually made it to our TV screens. During season 11, it is confirmed Meredith was 5 years old in 1983, when her sister Maggie Pierce (Kelly McCreary) was born. That would mean Meredith was officially born in about 1978.

Since it’s too difficult trying to figure out exactly what year it is on Grey’s Anatomy — it’s doubtful even the writers worry about that anymore — let’s simply accept that, at this point, each season reflects its corresponding year. Between all the time jumps, that has to be close enough to true.

So, Meredith Grey is likely 39 and looking at her 40th birthday party sometime soon.

Maggie Pierce

Age: About 34-35

If Meredith is about 39, that makes her 1983-born little sister about 34.

Jackson Avery

Age: About 39

Jackson Avery (Jesse Williams) and Meredith were in parallel years during their residency programs. That means they should be about the same age.

However, it’s possible Jackson is a year younger than Meredith, as it is likely her aforementioned time backpacking through Europe made her start medical school a year later than expected. Meaning, the majority of the students in her class, like Jackson, might be a year younger than she is.

Alex Karev

Age: About 39

The logic around Jackson’s age also applies to Meredith’s local BFF, Alex Karev (Justin Chambers).

Jo Wilson

Age: About 31-33

Alex’s wife Jo Wilson (Camilla Luddington) entered the Grey’s world in season 9 as a first-year intern. If we’re going by simple math — and the assumption she began interning at 26 — she should be somewhere between 31 and 32. However, considering the hell Jo had to go through to get to Grey Sloan Memorial, including running away from her abusive husband Paul (Matthew Morrison) and changing her identity, it’s possible Jo is a little bit older than her assumed age.

Restarting your life takes time.

Miranda Bailey

Age: About 41-43

At the start of Grey’s Anatomy, Miranda Bailey (Chandra Wilson) was three years ahead of Meredith. So, she should be anywhere between two and three years older than Meredith (again, remember if Mer started medical school a year late, someone who is three years ahead of her in medicine on a traditional track would only be two years older than her).

Andrew DeLuca

Age: About 29-30

Meredith’s fantasy man — at least in her dreams — Andrew DeLuca (Giacomo Gianniotti) began his first-year residency in season 12. So, in season 15, he should be somewhere around 29 years old.

Derek Shepherd

Died at: 49

Everyone seems very confident Derek was born in 1966. That would mean when Meredith’s husband died during season 11, which took place in late 2015, Derek was 49.

It would also mean there was a 12-year age gap between Derek and Meredith.
