Chapter Text
DC comic books exist in a shared continuity in which events from one story can influence another. For this reason, I find it interesting and beneficial to try and consider when the comics occur relative to one another.
But BOY does DC not always make this easy! Of course, it's normal for fictional characters like Charlie Brown or the Simpsons to exist frozen in time. However, comic book characters are different in that they're part of an ongoing serialized narrative rather than a "status quo," and yet despite this they too are frozen in time, except only sort of because sometimes time DOES pass for them. Or sometimes, the stories will SAY that time passes but then later retcon it so that time didn't pass after all.
Most recently, for instance, the event "Absolute Power" was published in 2024 and is said to occur in late summer / early autumn. After that came the comic "Batman/Santa Claus: The Silent Knight Returns," in which the characters all celebrate Christmas, and plot threads from after Absolute Power are continued upon. Next year, we get "I Saw Ma Hunkel Kissing Santa Claus," and then Supergirl (2025) #9 in which Supergirl celebrates New Year's. So far so good. We've followed cleanly from 2024 into 2026.
But then we get Justice League Unlimited (2025) #19-21. A newspaper clearly shows that this story occurs in June. Going by the holidays that have passed, this should be June 2026, which matches the publication date. And yet, the characters say that Absolute Power happened "a few months back." But that was two Christmases ago! It should have happened almost two years ago!
The comics are full of this sort of thing. For whatever reason, DC editorial wants lots of events to happen but for very little time to pass. Every major event in DC comics history happened "recently," which results in decades of comics happening in extremely short timespans.
So for Part 1 of my timeline ramblings, i want to not worry about the precise dates of things. Instead, I want to lay out the timeline of the DC Universe, as I think it works according to DC editorial.
A further wrinkle in all this: DC comic lore gets retconned and rebooted quite a lot. Since such changes can be controversial with fans and make prior stories feel "unimportant," DC editorial has lately learned to retcon things quietly without really announcing it or even making clear what exactly has been changed. Most recently, the New History of the DC Universe miniseries enacted a pretty major series of retcons and more or less serves as a "reboot" even if DC isn't calling it such. So I would argue that anything published after New History is "more canon" than things published before it. "Post-New History" comics definitely happened, whereas "Pre-New History" comics only sort of happened. All comic books are canon, but some comic books are more canon than others.
Anywho, let's take a look now at our "Post-New History" DC Universe, based on how I think DC editorial probably thinks about it:
42 Years Ago
Baby Kal-El crash lands on Earth.
Action Comics #1098 shows that the Kents in the current continuity visited a fertility clinic prior to the spaceship crashing. That would place this in 1980 at the earliest, when the first IVF clinic opened in the US. You could say science progresses more rapidly in the DC universe, but I would argue this detail is probably a deliberate reference placed by the writers to give a clue about when this is taking place.
8 year old Bruce Wayne's parents are killed. According to New History of the DC Universe, he leaves soon after this to travel the world and train as Batman.
29 Years Ago
Published shortly after New History of the DC Universe (2025) #2 and immediately retconning it, Titans Annual 2025 establishes that Diana rescued Donna Troy from an apartment fire when she was a baby, drawn to look probably 1 year old (The comic also says she lived with a foster family for "about a year" before the orphanage fire so we know she's at least 1). It also establishes that Donna is roughly the same age as Dick Grayson, meaning Dick must also be a baby during this time.
This means Diana has been retconned to have debuted BEFORE Superman and Batman, overriding what New History of the DC Universe says. Her rescue of Donna even got a newspaper article written about it, so the public knows about Wonder Woman (meaning you can't fanwank and say that Diana was acting as Wonder Woman in secret before her "debut" or anything like that).
Of course, you could argue there was some form of time travel or magic age-up involved, but that's really not what Titans Annual 2025 implies. It's also mentioned that her biological dad was able to figure out who she is because she looks so much like her biological mom. If she were a different age than he expected, he probably would have assumed she was some other relative, not his daughter specifically.
Also worth noting is that Wonder Woman (2023) #36 establishes that Diana was born AFTER Hippolyta's WWII adventures. She's likely around the same age as Batman and Steve Trevor, as opposed to some versions of Diana in other continuities who are centuries old. Wonder Woman's Dawn of DC era comics mention that she became Wonder Woman when she was "just a girl." It's also possible she ages a bit more slowly than a normal human.
27 Years Ago
15 year old Clark Kent debuts as Superboy.
The current run of Action Comics takes place during Clark's time as Superboy, and it shows computers in the home and in school. That would place this in the mid-1980s at the earliest (Logically, it should be in 1995 at the earliest due to the fertility clinic seen 15 years ago). It's also definitely set before the rise of smartphones.
22 Years Ago
Probably around age 20, Clark Kent is renamed from Superboy to Superman (He’s technically a bit older than 20 since he spent an unknown amount of time having adventures in the future with the Legion of Superheroes, but the world would assume Clark Kent is 20, anyways).
If we take the DC Black Label comic Jenny Sparks (2024) as canon, then Clark was SuperMAN sometime during the Iraq War, which would be 2003 at the earliest and 2011 at the latest.
On his birthday, Bruce turns 28, and soon afterwards, he debuts as Batman.
20 Years Ago
Dick Grayson turns 10. In August of Bruce's third year as Batman, Dick's parents are killed, and 3 weeks later he debuts as Robin (according to Batman and Robin: Year One).
15 Years Ago
Barbara Ann Minerva becomes the Cheetah.
Justice League and Teen Titans form.
According to Titans Annual 2025, the Teen Titans were around for a "few years" before Dick became Nightwing.
Roy Harper's daughter Lian is probably conceived somewhere like 14 to 15 years ago. The comics also had her spend years getting "teleported across time" and uses that to sidestep questions about her age.
Somewhere from 13 to 15 years ago, Bruce and Talia conceive a child, Damian Wayne.
11 Years Ago
Okay, get ready, this is a huge year for DC comics history!
Sometime shortly before Dick becomes Nightwing, Earth-3’s Lois Lane AKA Superwoman is seen pregnant with Earth-3’s Jon Kent.
Around now is when the Batman/Superman World's Finest (2022) comics are set. These comics shows a 2010s era Youtube and iPads. Titans Annual 2025 also shows a laptop around this same time.
Dick turns 19 and becomes Nightwing. Donna Troy is also 19 around this time and gets married (Her age is confirmed in Titans Annual 2025).
Around the time Dick becomes Nightwing, Clark gets Lois knocked up. Can't believe the Big Blue Boyscout did it out of wedlock!
Roy Harper meets his daughter Lian Harper for the first time around now. Lian's precise age is unclear, but she's definitely a baby.
The Crisis on Infinite Earths
14-to-16-ish year old Billy Batson becomes Captain Marvel. He seems to be "forever 14-16," never aging like he should.
The Jon Kent of Earth-3 is born. He’s a couple months older than Prime Earth’s Jon Kent.
Clark Kent and Lois Lane get married while Lois is already pregnant.
Lex Luthor is elected president of the United States. Of course, that would mean "12 Years Ago" would have to fall upon an election year, but DC editorial doesn't care about such details.
Jon Kent is born.
Wally West's kids, Jai and Irey, are also born around this time. The Flash (2023) #6 says Wally's kids are 13 and a half in the "present day." However, with them being born around the same time as Jon Kent, their ages must have been retconned since Superman Unlimited #15 proves that basically no time has passed since Jon was aged up (The point of timeline retcons is generally to keep the characters from getting too old, so I'm more inclined to think Jai and Irey have been retconnected to 11 year olds as opposed to thinking Jon Kent was retconned into being 13-and-a-half before his time travel age up). It could also be that they gained some extra years from their time in the Dark Multiverse somehow. Maybe time flows differently in other dimensions?
Shortly after Jon's birth, Damian Wayne debuts as Robin. Damian was "artificially aged" to 10 (His debut age of 10 is reaffirmed in Batman 2025 #11). Strangely, Damian ages much slower than he ought to, and the characters in-universe seem to be unaware of this fact. However, he debuted in comics published in 2006, which is also when Jon Kent was born (during Infinite Crisis), and New History of the DC Universe indeed seems to suggest that Damian was artificially aged to 10 when Jon was a newborn.
In Batman (2025) #11, Damian says he read The Great Gatsby when he was 6. I think probably Damian here was counting his literal years without artificial aging in order to make himself sound more impressive. He was never "physically" 6. But that does at least prove he has physically existed for at least 6 years.
5-6 Years Ago
The "Flashpoint" storyline occurs when Jai and Irey are about 5-6.
Around now, sometime during the "New 52" era, Harley and Ivy Life and Crimes (2026) takes place. They reference the phrase "believe women," which suggests the Me Too movement has already begun, which should place this in like 2017 at the earliest, relative to the "present day" of 2026 (although this comic is being narrated by Harley as a framing device, and she could be an unreliable narrator).
1 Year Ago
Shortly after turning 10, Jon Kent debuts as Superboy.
Sometime soon after Damian turns physically 13, they form the iconic Super Sons duo. Damian chronologically ought to be much older than 13, but for whatever reason he has aged only 3 years in all the time it took Jon to grow up.
0 Years Ago
Jon Kent, age 11, goes to the future and ages up. Superman Son of Kal-El #9 confirms that he aged from 11 to 16.
Ever since that moment, time has been "frozen" despite plenty of events occurring. That's how Damian is 14 in 2021 and still 14 in 2025. Billy is likewise frozen at age 16.
Think of it like the Red Queen's race from Through the Looking Glass. No matter how far you run, you never go anywhere.
The clearest example of this is Superman Unlimited (2025) #15. The entire plot of this issue is about Jon Kent of Earth-3 impersonating Jon Kent of Prime Earth. But we saw that Earth-3 Jon's mom was pregnant with him during the "Silver Age," before the Justice Society met the Crime Syndicate and therefore also before Dick became Nightwing. Furthermore, the way that the characters talk, the situation would only make sense if Jon hasn't been aged up for very long. Earth-3 Jon was born before our Jon and is "from the present," and yet he's so close in age that the two are mistaken for one another? Even after adding on the pregnancy gap between the two Lois Lanes and whatever time our Jon has spent as an adult by now?
It only makes sense if Jon's age up happened fairly recently and the gap from early Silver Age to Infinite Crisis is also extremely small.
You'd think that at least 9 months should have passed from Jon's age up because of the birth of Wally West's son, Wade West, but that happened well before the publication of New History, so I consider its status in the current canon to be more fluid. Maybe Wally's wife got pregnant earlier in the Post-New History continuity?
As of me writing this on August 6, 2026, the "present day" of the DC universe seems to be 2026. In Justice League Unlimited (2025) #19, we see a newspaper dated June 5. In Superman (2023) #38-40, set right before the Justice League issue, it's said to be a Wednesday, which would make it Wednesday, June 3, 2026. That lines up perfectly, which suggests to me that DC editorial was looking at the 2026 calendar as a reference.
Of course, that's going to get retconned again as soon as they feel the characters are growing too old. The characters have been allowed to age somewhat at times, though, such as Bruce mentioning in DCKO that he's getting really old by now.
Personally, I hate comic book sliding time and think it leads to bland, stagnant storytelling, but it is useful to at least understand how it works and what the creative intention is.
What this doesn't help me with, though, is understanding when exactly particular comic book issues occur relative to one another. Time is so squashed, it seems like all the comics are happening at once, which just makes it all more confusing!
Grr! If only someone were to actually skim through the past several years of comic books and count the exact number of days that pass! But that will never happen. No one is that neurotic.
NEXT TIME: I COUNT THE EXACT DAYS THAT PASS, ISSUE BY ISSUE
