Here are all the birthdates I know of that are canon somewhere in DC, with a preference for the main comics continuities. I have included exact sources and image references when possible. I am not including character introduction dates, just actual birthdays.
If you find any other sources for Batfamily birthdays, please do share!
A moment of silence for Batfamily characters who donāt have canonical birthdays yet, so far as I know. This includes Damian Wayne, Stephanie Brown, Duke Thomas, and more. :(
Summary
Source images will be further down, but hereās an overview in roughly age order (Iām not sure of Kate vs Selinaās ages) with the dates the birthdays were introduced and used:
Tim Drake: July 19th (from 2003)
Jason Todd: August 16th (from 2004)
Cassandra Cain: January 26th (from 2002)
Helena Bertinelli: February 14th (in the Batman: The Brave and the Bold universe, from 2010)
Helena Wayne: September 7th (from 1984), potentially October 20th or the 22nd of unknown month or maybe October 22 or maybe Feb 28th (all the New 52 on passports from 2011-2012). These could also be New 52 Helena Bertinelliās birthdays or nobodyās birthdays. who even knows.
Dick Grayson: March 20th (from 1995), October ~24th ish (from 1990), November 11th (from 1976), December 1st (on Earth-16 in animated Young Justice universe, from 2012)
Barbara Gordon: September 23rd (from 1976), sometime in fall (from 1987)
Selina Kyle: March 14th (from 1976)
Kate Kane: January 26th (in BatwomanĀ TV series from 2020), March 21st? (word-of-god by J.H. Williams III from 2012)
Bruce Wayne: October 7th (from 2021), February 19th (from 1970s various to more recently), April ~7th (from the late 1940s)
Jim Gordon: January 5th (from 1976)
Alfred Pennyworth: April 8th (from 1976), August 16th (in the Injustice: Gods Among UsĀ universe, from 2016)
Note: in this post when I say āmain comics continuity(s)/universeā Iām referring to anything thatās been a āhomeā continuity for the comics at some point. For example, pre-Crisis Earth-2, Earth-1/New Earth, and Earth-0/Prime Earth, as opposed to Elseworlds or DCEU earths that are still part of the broader DC multiverse but have never been the primary continuity of the comics.
Below are further details and source panels.
Details and Sources
Tim Drake
Tim has only been given one canon birthday. He turned 16 on July 19th in Robin Vol. 2 #116 (cover date Sep 2003).
Robin Vol. 2 #116 (Sep 2003)
Jason Todd
Jason turned 18 on August 16th in Detective Comics #790 (March 2004). This is his only canon birthday.
Detective Comics #790 (Mar 2004)
In post-Crisis/preboot (1986-2011) continuity, there was a gap of six months between when Jason died and when he was resurrected (Batman Annual 25). Jason died April 27th according to his death certificates in Batman Annual 25 and Batman Files 2011, so he wouldāve resurrected near late October.
Batman Annual 25 (May 2006)
So, it could be that post-resurrection Jason is biologically 6 months younger than he chronologically should be. But honestly, do we even really know what multiverse-breaking resurrection punches and then a Lazarus Pit on top of that do to someoneās body??? Either way itās just much more simple to just use his chronological age.
Cassandra Cain
Much like Tim and Jason, Cass has only ever been given one birthdate: January 26th from Batgirl Vol. 1 #33. With that birthday, she turned 18 in Batgirl Vol. 1 #37.
Batgirl Vol. 1 #33 (Dec 2002)
When Jan 26th actually comes, Bruce suggests David Cain couldāve lied about it, but Cass denies that idea and continues to treat the day as her birthday.
Batgirl Vol. 1 #37 (Apr 2003)
Why it's likely her real birthday: Bruce initially believes Cain mustāve lied because he doesnāt think Cain couldāve known her birthday. However, we later learn Cain had lied about her origins and was actually her biological father. Batgirl v1 #62 and #73 show he was there for her birth and could absolutely know the date.
On top of that, in Batgirl #37 Cass remembers celebrating her birthday with him as a child, so he did seem to actually keep track of it. I honestly donāt see any reason to believe heād lie (Bruce is just a jealous spoilsport).
Helena Bertinelli + Wayne
Iām combining them here because the New 52 gives me a headache.
Helena Bertinelli celebrated her birthday on February 14th in a spin-off comic from the animated Batman: The Brave and the Bold series. This is obviously not part of regular comics continuity and the characters differ from the usual comics in many ways. And yet, for reasons that will soon be clear, itās my favorite for actually being about Helena Bertinelli the Huntress and for not being an utter mess.
Batman: The Brave and the Bold #14 (Apr 2010)
In a character profile at the end of Infinity Inc. #7 (Oct 1984), Helena Wayneās birthday was September 7th, 1959. Calculating back from October 1984, that would make her 25 at the time.
During the New 52, Helena Bertinelli was initially portrayed as a long-dead (secretly alive but donāt worry about it) mobsterās daughter and replaced by Earth-2ās Helena Wayne who got stranded on Prime Earth. This H. Wayne stole H. Bertinelliās identity in the form of several forged passports and IDs, which had hints toward birthdates. The question is, can we take any of those birthdates seriously, and if so, which birthdates and for which character? (Cue my headache.)
Skip ahead to Dick if overthinking fake passports sounds boring.
When comparing to a real Italian passport, the date on H. Wayneās fake Italian passport appears to be a birthdate. Note that the fake name is Carol Bertinelli, not Helena. H. Wayne said her IDs were inspired by H. Bertinelli but clearly sheās taking liberties for the IDs so thatās a point toward these being useless for H. Bertinelli birthdays.
Huntress Vol. 3 #1 (Dec 2011)
I donāt recognize the month abbreviation as a real abbreviation, but from the visible letter O Iām going to assume it means October. If it is, then the date is 20 October 1985. Sidenote: a 1985 birthdate during 2011 could put her age at about 26, which is actually quite close to how old she couldāve been based on pre-Flashpoint! 1985 has been given as Helena Wayneās death year before, so itās an interesting choice of a birth year for her. (Thanks to DCās sliding timescale, though, birth years donāt actually mean anything in the comics.)
They donāt show her complete US passport, but I can see a ā22ā in line where the day of the month should be for her birthdate. This already contradicts the previous passport. This one uses Helena Bertinelliās actual name, thoughādoes that make it more relevant than the Carol one or this all still ridiculous because of the discrepancies?
Worldsā Finest Vol. 1 #1 (Jul 2012)
We can try to glean the US passport birth month from the passport number at the bottom. The first two digits (ā12ā here) indicate the agency that issued the passport. 12 means the Honolulu agency. Right after āUSAā is supposed to be the birthdate plus an extra number, in the order of year/month/day with the year being the last two digits of a year. Here we encounter another problem. It says 810228. This would imply her birthdate is 1981/02/28. Thatās February 28, 1981. Since the earlier line indicated her birthday fell on a 22nd, this already contradicts itself.
Interpreting a Machine Readable Zone (MZR) on a Machine Readable Travel Document (MRTD)
However, Iād bet comic writers and artists arenāt always well versed in passport numbers (itās already a stretch for me to bother checking itā¦). If they put the extra digit before the birthdate instead after, and the date is formatted month/day/year (the most common format in American English, so probably their first instinct), then we can drop the first 8 and itās 10/22/8[?] with the last digit unknown. This would put her birthday as October 22, sometime in the 1980s. The 22 matches the earlier line, the October might match the previous passport if that really did say October (but contradicts the 20th), and the 1980s year could be 1985 to match the Italian passport.
At the end of the day Iām personally just going to let Helena Bertinelli be a Valentineās born baby and call it a day, unless/until she gets a better one in the comics. For Helena Wayne Iād easily pick September 7th.
(My question is: did they give the crossbow vigilante a Valentineās birthday as a Cupid joke??)
Dick Grayson
Dick has probably had the most birthdays of everyone (unless Bruce has more I donāt know about). All of them have their drawbacks.
In a main comics continuity, his most popular and most recent is āthe first day of springā so probably March 20th. This comes from Robin Annual 4 when his mom says she calls him Robin because he was born on the first day of spring. That presents some problems since there are other explanations given for the origin of āRobin,ā including that his mom said he was āalways bobbinā alongā (Dark Victory #12, page 17) or the original inspiration of Robin Hood (Detective Comics #38, p3).
Robin Annual 4 (Jun 1995)
Before that, in Secret Origins Vol. 2 #50 (Aug 1990), Marv Wolfman wrote a version of Dickās origins where Dick turned 10 a week before his parents died on Halloween. That would make his birthday October ~24th (presuming that āa weekā before Halloween literally means 7 days here).
Secret Origins Vol. 2 #50 (Aug 1990)
The first drawback of the October birthday is that itās tied to Dick being 10 when his parents die on Halloween. Dickās age and the date his parents die change a lot depending on the writer (Nightwing Vol. 1 #1 says his parents died June 27th, Dark Victory #8-9 says May, etc.). The second drawback is that few people remember this version of his birthday even exists.
Dickās birthday is November 11th in Super DC Calendar 1976. Note: Despite being a non-diegetic calendar from almost 50 years ago, this source remains well known and used among comic enthusiasts (including those working at DC). Generally, I would say it should mainly apply just to pre-Crisis continuity, but it is also useful for characters that havenāt gotten updated birthdays ever since (like Roy Harper, Barbara Gordon, or Selina Kyle, for example).
Super DC Calendar 1976
Sidenote: Since Damian doesnāt have a canon birthday, November 11th is favorite to steal for my own fan canon Damian birthday. Dick has plenty birthdays to share and I think itās cute. @ DC, give Damian and Steph birthdays, theyāve been birthday-less for decades!
Indeed, DC writer Tim Sheridan and editor Mike Cotton debated whether Dickās birthday was in March or November. They favored March 20th and wrote a birthday scene in Teen Titans Academy #1 (published March 23rd, 2021). The publishing time near Dickās birthday was intentional, though the date isnāt mentioned within the comic itself.

The above birthdays were all meant to apply to a main comics continuity at some point. However, Earth-16, better known as the animated Young Justice universe (therefore outside of main comics continuity), says YJ Dickās birthday is December 1st.
Young Justice Vol. 2 #20 (Nov 2012)
Unlike Helena Bertinelli, Dick has plenty of comics birthdays to choose from, so personally Iāll only count Dec 1st as being the birthday for YJ animated/Earth-16 Dick Grayson until or unless itās ever mentioned to apply to main comics continuity.
Barbara Gordon
Super DC Calendar 1976 says Barbaraās birthday is September 23rd.
Super DC Calendar 1976
Since then, the only time I recall her birthdate hinted at is in Secret Origins #20 when her adoptive mom says her birthday is in the fall. This could support her birthday being September 23rd.
Secret Origins Vol. 2 #20 (Nov 1987)
Although she has celebrated her birthday on panel since then (the end of Nightwing Vol. 2 #153), she hasnāt been given any other actual birthdate. So Iāll keep September 23rd and call it a day.
Selina Kyle
Super DC Calendar 1976 says Selinaās birthday is March 14th. Once again, although it hasnāt been mentioned within a comic, itās stuck around in popular consciousness (see: Catwoman actress ZoĆ« Kravitz wishing Selina a happy birthday on March 14th).
Super DC Calendar 1976
Selina celebrated a birthday on panel in Catwoman (2002) #37 but the date was never mentioned. I donāt know of any other reference to her birthday, but my reading of Selina is thus far more sparse than my reading of the others.
Kate Kane
Kateās birthday options all come from outside of the comics themselves.
In āAn Un-Birthday Present,ā season 1 episode 11 of Batwoman, a parallel version of her twin Beth had a driverās license showing her date of birth as January 26, 1990. She and Kate later celebrated their birthdays on an episode aired Jan 26th, 2020. I donāt keep up with live action DC shows so I unfortunately canāt offer a screenshot (if anyone has one or the timestamp, please let me know!).
(I kinda wonder if somebody looked up Batwomanās birthday for these episodes, saw Batgirlās (Cassās) birthday, and just ran with it. Batwoman and a Batgirl sharing a birthday is just. Ughhh.)
In 2012, one of her comic writers tweeted to choose a random date for her birthday and picked March 21st, which so far as I know has never been used as her birthday in comics.

Bruce Wayne
Bruceās most popular birthday is February 19th, but his most recent one is October 7th from the digital-only comic Legends of the Dark Knight. I believe thatās the only time October 7th has been referenced, but Iāve heard the animated show The Batman said his birthday was in October (canāt confirm, havenāt watched it recently).
Legends of the Dark Knight #10 (Jun 2021) - Note: two pages have been combined into one for this post
Still, even associates of DC seem to remember his February 19th birthday better. In February 2023, Warner Broās Gotham Knights game did a sale for Bruceās birthday. Iāve also heard the birthday was used in the Gotham TV show, but again, I donāt watch much live action DC shows.
The February 19th birthday appears to come from the 70s and 80s. Itās his birthday in the Super DC Calendar 1976,Ā and in Batman Family Vol. 1 #11: āSuprise, Suprise!ā (May 1977). Bob Rozakis (known as DCās āAnswer Manā) said Feb 19th was Bruceās birthday in the letter column of Detective Comics #494 (Sep 1980).
Letter column of Detective Comics #494 (Sep 1980)
Batman Family Vol. 1 #11: āSuprise, Suprise!ā (Jun 1977)
Super DC Calendar 1976
Way back in the 40s, his birthday was in April, possibly April 7th. During a birthstone murder mystery, Bruce says his birthstone is a diamond, which is traditionally the April birthstone.
Star Spangled Comics #91 (Apr 1949) might imply the exact date was April 7th but weād have to assume the party is on his birthday and that āthis monthā refers to the publishing month of April. I believe this is where people get the April 7th birthday when they bring it up.
Star Spangled Comics #91 (Apr 1949)
Early April also shines in Batman: Year One where it shows Bruceās first night out as Batman being either the night of April 6th or the early morning of April 7th (Batman #405). So although the April Bruce birthday hasnāt been used in decades, itās still a Batman birthday in a way.
I have also heard people say Frank Miller considered Bruceās birthday to be in November. However, I have yet to find an original source of him saying that, and honestly (just like the āMarch 21stā birthday for Kate) if he never used it in any canon material I donāt put much weight in that.
Jim Gordon
The only birthday Iāve ever seen for Jim is January 5th from Super DC Calendar 1976.
Super DC Calendar 1976
Alfred Pennyworth
Alfredās birthday in Super DC Calendar 1976 is April 8th.
Super DC Calendar 1976
In the Injustice: Gods Among Us universe (an alternate reality where the video game of the same name is set in), they show Alfredās birth certificate, where it says his birthday is August 16th, 1943.
Injustice: Gods Among Us Year Five #26 (Jun 2016)
Maybe youāll notice that August 16th is Jasonās birthday. A little funny considering the issue features Alfred refusing to share his birthday only for us to learn itās the same date as Jasonās. Still, annoying. There are so many days in the year! Stop choosing the same ones!
This Alfred birthdate runs into a similar problem Helenaās birthdates did: itās not part of main comics canon, itās an alternate universe, so it may not be applicable to the main comics universe.
Note: if we calculate that 1943 birth year from Jun 2016 when the comic was published, thatād make Alfred 72 soon to be 73. Does that mean anything in canon? Probably not, but oh well. Also...token British character born by Windsor Castle? ā¦of course.
Personally, I would rather go with the April 8th birthday than the Injustice one, since Injustice is an alternate universe. Also, outside of the humor of it, the idea of Alfred and Jason sharing a birthday is a bit too much for me. Still, itās up to peopleās own cherry picking.

Itās important to me that dick Grayson is a ānightmareā child and Bruce loves him unconditionally anyways like it doesnt really phase him at all
Dick hits and bites and yells and scares off therapist and has intense mood swings and Bruce doesnāt care thatās his lil Robin
Because Bruce remembers being the nightmare child and how every adult didnāt get it and even the good old fashioned āI hope you get a kid like yourself one dayā and Bruce does and he loves him
