This was ridiculously fun for me!

I got 2827 as a score which isn't that great, but I nailed the year perfectly on 2/5. Super interesting!


Also nailed 2 out of 5, but managed a 4154 on my first go :D

It's interesting to think about the epochal details our minds use to produce these guesses. Technology like the cars/cameras/phones present (or missing), the fashion styles on the people, the quality/sharpness of the image overall, face masks in post-2019 photos, etc.


This would be fun as a team or on a stream. Theres a lot to learn from the "speak aloud" aspect of the reasoning here. Film grain. Colour. Hair. Clothes. Cultural clues. Etcetc

Absolutely love these types of games. Geoguessr is another classic.

EDIT: oof, just got the Columbine High School class photo.


I prefer Explordle to Geoguessr

Fun game! Wish the UI would stay static when going between rounds. The scroll down was jarring.

This was a lot of fun. Very unique game. Congratulations on making it! :)

That‘s fun :-) What‘s the source of the photos?

This is really fun! Never really thought about how nice some very old film photos can look, took me by surprise on a few ones!

This reminds me of some TV show games here in Sweden. :)

Got a perfect 1000 points on a pretty gruesome WW2 photo with jews around a train. Sort of a pyrrhic victory there... :|

~2200 on my first try, a lot obviously thanks to That Photo.


På spåret :)

Fun game. Does stutter a lot in Firefox on my phone for some reason.

No problem here, latest ff, s10e.

Awesome.

The first photo I got was some guy in a cartoonish space suit talking with a kid at a festival. I guessed 1966 and got it on the nose. That heartened me.

After 3 rounds my high score was 3154


Nice to see an unique game!

Wow… for the first time in my life, knowing intricate information about film development colouring paid off

It's tricky. I got one that was full bright standard colour... from 1912. Normal contrast a and hue and saturation, no noise. I assume recoloured later?

There are bw photos from 70s and colour photos from 50s. Contrast and noise and hue can give clues, but nothing stops a photographer from using old film in new times. I ended up going for cars and styles more when possible.


Fair point! Maybe I just got lucky and my 5 or so photos were all time accurate to their development methods!

> I assume recoloured later?

Color capable film has been around since the late 19th century.

https://en.wikipedia.org/wiki/List_of_color_film_systems


Sure, but the character of the saturations and hues is different. I think that’s what parent is talking about.

A bit like the car meta in Geoguessr

People still use old film sometimes ...

do geoguessr style livestreaming but for old photos and talk thru your process, people will love it

yes, I would 100 percentage watch it

The slider was incredibly frustrating to use on (Android) mobile. The game itself was fun though.

Works fine for me on Android. Perhaps a fix was made in the 4 hours since you posted your comment and me trying it.

It's fixed now. It wasnt't finely grained enough before, so you'd try to select 1978 and end up with e.g. 1979 or 1980.

Very fun, almost wish there were less overt cultural clues though. I got 3912 on the first go but it was mostly because I recognized Bowie and Le Corbusier, and got a theater marquee with Happy Gilmore playing.

I enjoyed the pics where you needed to analyze hair/clothing styles and car models more.


One of mine had a picture of JFK giving a speech.

It said Clinton Shaking Kennedy's hand was 1962... thought it was 63

Well it certainly wasn't 1964

Definitely no later than 65

Very nice game, fast site, nice photos and likes the overall feel of it, well done!

3 rounds and 3502. Well done to the creator!

I'd love to see trends and stats on the photos across regions and collaboratively filtered (e.g., someone who accurately predicts photo XX is more likely to accurately predict photo YY).

Also, it's a super curious dataset, photos with year metadata.


Simple and fun game. I just wish the score was more forgiving the older the photo was. It’s a lot harder to tell 1905 and 1910 apart than 2015 and 2020, from the perspective of 2023.

Interesting, unless there was a major clue, I've had as much pain in both cases.

I always got the most points when I just did a completely random guess haha. Taking the actively misleading part out of the equation.

I found 1973-1997 looking very similar in color film quality, and cars on the street. maybe if I was more familiar with models, maybe.

it was only obvious it was 80s or 90s if something silly was going on.

my top score is 2900 right now


Changes in consumer-grade photo quality between 70s/80s/90s are actually quite visible if you've looked at many of them. It's subtle, but e.g. newer ones have better range in brightness, i.e. less overly bright or dark areas in high-contrast images.

First time 2200.. what a fun game. I'll use your 2900 as a goal

I got a bunch of Edwardian—WW2 photos in one go, and netted 3190. I might be able to get higher than that, but only if the photos predate 2000.

I think styles changed a lot from 1900—1970. After that, things are pretty hard to distinguish; retroactive clothing styles muddyvthe waters.


got 3632! and now my watch has ended

One of the photos was labeled with the year, and the game identified it differently. It's all in fun.

I was finding that I had a harder time with very recent photos. Fashion has become a bit static perhaps.

Actually I've been doing consistently worse in the years I lived through than the rest of the timeline. Apparently the older I get the more styles blur together. I tend to estimate ~5 years too early for the 1980-2000, and ~10 years too early for 2010 to present.

Disagree, it’s just a matter of analyzing each decade precisely

Thought often the pictures are not a great representation of the time they convey :/


I love this. The summary at the end could be a bit more compact. Scrolling all the way to the bottom to start a new page is a bit inconvenient.

Maybe full points for scoring within 5 years? Some photos are very hard to place in an exact year.


Use stylebot (chrome) for these type of sites. 1 min or so the site would to your taste.

This is a fun little game. It is interesting to see what the tells are for the time periods. The reliable ones for me so far are military uniforms, cars, and computers. Hairstyles and clothes for some time periods are a give away, but some of those have thrown me off too.

Helped for me that I am in one of the photos (NHL game played at Lake Tahoe during the pandemic).

That is fantastic. Gotta wonder what the chance of that is.

This is very similar to Wikitrivia: https://wikitrivia.tomjwatson.com/ , which asks you to place general historical concepts/events on a timeline.

Not sure how similar it is, but hey Wikitrivia is great!

Amusing. Summary screen is hard to read and kinda redundant, needs a leaderboard.

Don't these always end up getting spammed by script kiddies submitting the best scores?

Love it! I got some terrible scores but then realized a good trick is to judge a photo by its quality and aesthetics rather than the content.

Nice, I always thought I’m pretty good in guessing the production years of movies, photos, and music, so this game is a lot of fun for me.

My first try gave me a score of 4125. I’m curious if I can replicate that result or if I just got lucky!

Edit: Nope… second try: 2728

Edit: 3rd round: 3823


It’s incredible to see how quickly things changed ~1910-1930 in terms of infrastructure and technology. You’re going from horses and cobblestone to almost modern cars and pavement, within just 20 years or so.

Same thing with smartphones. If the photos is of a crowd, it is immediately obvious if it is after 2012 by the fact that everybody is watching their hands.

I would say that change happened much earlier, and was almost complete by 1911 in many US cities. OTOH I had a hard time telling apart cars from 1910s vs 1930s. Around the early/mid 30s a much more modern style of car came on the scene (Ford Phaeton etc. I guess), but I suppose it took a while before the Model-T style vehicles were all replaced.

Great game ! Thanks for sharing.

Small suggestion: it would be great to get some information about the picture (location, context, people) in addition to the year, after we tried to guess the date.


I feel proud and eager to share my 3150 score point.

PS: No such sharable gold nugget was presented.


Lol I took a screenshot. Endorphin hit from getting 2 in a row exactly right was ridiculous

that's the good stuff

This is a AI training job gamified isnt it?

What would be the help of this game to ai?

Potentially, it might help find errors in the existing year-labeling - either via recognizing cases where guessers have wide divergences with a certain bias, or the explicit avenue via the about (email with errors).

Or, help identify features of a photo that definitively place it at certain times, by human perception. That might help tune autogenerated content intended to reflect certain eras to avoid anachronisms, or more strongly hint specific years or vague ranges.

Now, I don't think these are likely motivations for the game – the mere fun of playing seems enough to me. But it seems they could be.


Pretty far fetched. The date of the photos are known so ai's only intention would be to find out if humans suck at guessing or not. Which would be a useless data to improve the systems.

But some of the dates have errors, which one might, in some applications like to find.

And alternatively, how well a scene matches the audience's clear indicators of era is valuable in entertainment – even moreso than accuracy, in some cases.

Again, I don't think these are likely motivations for this particular system. But in a wide world of many aims, it's within the realm of possibiity that someone might try a system like this for such purposes.


I love how there are no instructions, and yet it's pretty obvious what the goal is and how to achieve it, good UX.

Yes. Is a great example of "less is more"

[dead]

for the first 30 seconds with the "Submit" button I thought it was a crowdsourced analytical thing though. Almost bounced. Might be worth changing the wording but otherwise agree

Reminds me of the Timeline (I think this is the name) card game where every player has a bunch of cards, each of which represents a historical event (e.g., moon landing, or sinking of Titanic, discovery of Radium, etc. Each player has to put down the card in the proper order, with respect to previous cards played. It gets harder as more cards are "on the timeline". Fun game.

Yeah, it's called Timeline. At work we took Armenian colleagues to a pub which had it available. It was funny to play with the Polish localization, they understood more than we assumed (Armenians know Russian). But the replay value is dubious. The guy who won turned out to have this game at home. Kinda cheating ;)

In the U.S. we have Chronology, sounds like the same game.

This link (grabbed from another thread here) is similar.

https://wikitrivia.tomjwatson.com/


Timeline is easily found in the US. I bought a copy a couple months ago.

Love it!

You can tell a crowd photo wasn't taken in the last 10 years because nobody's looking at their phones.


* 15 years. 10 years ago is already 5 years after the iPhone.

Yeah, but it took a while for looking at your phone while walking to become normalised.

Love it! I got some terrible scores but then realized a good strategy is to judge a photo by its quality and aesthetics rather than the content.

Except when you don't do it. My first (and best) guess was one year off, because I guessed based on a specific war with a specific way of building trenches.

Yes, the war photos are way easier to place than like the lady looking at the jewelry.

Addictively fun. I'd love to see a leaderboard for this or at least what the score distribution is.

3244! The first photo was hard because it was recent but had an old car in it.

This is great! I'd love to see some stats on on the distribution of all guesses for each photo

It's a shame, but its privacy policy[1] is pretty clearly contravening the GDPR. There's a link on the top of the privacy page which seems to be supposed to show you a consent modal, but it doesn't work on my Chromebook, and their claimed justifications for using the user's data are clearly not actually justified.

[1]: https://www.chronophoto.app/privacy.html


This is really fun. My only wish is that I could see some information about the photos in the summary screen. Maybe a photographer credit or link to a Wikipedia?

it's fun! Would be good if each set had a unique id so that you coul send the same set to a friend and compare scores

Fun game, thanks!

I fancy myself to be much more historically than most people and yeah… no. Consistently off by 5 years or so.

In a range of 120 years that’s pretty good I’d say. At least, I was pretty proud of myself for doing the same.

I feel like this would work even better as a daily game like Wordle with the same 5 pics for everyone to play so you can (lightly) compete with friends.

And at the end, you could get some trivia for each of the photos


Why would this work better as a daily game like wordle?

I ask because I disagree. Visuals are far more infinite than guessing a 5 letter word with restricted choices. Chrono and Wordle are not comparable.


People like to compete: seeing the same questions makes the scores comparable. Having common context of the same "daily pics" also creates opportunities for discussion & debate which don't exist otherwise.

Trickling out synchronized games may create more durable entertainment, because otherwise many tend to play intensely until they bore of it, considering it "done". Checking back each day may generate more 'fun' per game, as well as having a built-in audience for incremental improvements/experiments that take time to implement & evaluate.


If it gets popular by going viral, the creator could sell it for 7 figures to the New York Times too.

Framed is pretty popular with some of my daily game friends, and it's visual.

https://framed.wtf/


This is great

Well I want to play it again

I wish it had a seed that you could specify.

The trivia thing was asked for at reddit too, but i looked into the file storage of the server and it seems that the photos are just plainly stolen from all over the internet with file names like chronophoto.app/years/1963/ap630629032-02fcaf4ca7736109b998d760283a3a9ba7bceda7-s900-c85.webp or chronophoto.app/years/2017/ed-jones-north-korea-top-100-photos-2017.jpg No credit is given anywhere too. This is probably illegal and the author will get in a lot of trouble if he does not do something about that soon.

> author will get in a lot of trouble if he does not do something about that soon.

probably worst thing that will happen is some kind of cease and desist.


Finally! A game I enjoy and am somewhat good at.

Neat simple little trivia thing, but fun to think about each one and any clues. I got 1969, 1968, 1971, 1906 and 1904, score of 3435. First two were war related, for 1000 and 777. First was b&w but obvious forest clearing mid Vietnam war, so bit of a guess but on the dot, then the second was a color picture of a bus with "Saigon" on it that I underestimated but again, era was clearly Vietnam. Second one showed people in front of cricket scoreboard and with all the batters names and that was pure luck for me because only one possible famous match featured those players! (test #679, Australia v Sydney 1971). Utterly bombed the next, 83 points, I agree with others that I found older photos tougher. Guess 1923, way off. Then I could guess at the final based on the period late 1800s/early 1900s dress at 1910 which was good for 575.

Anyway, fun in terms of trying different strategies and it making one focus on the details whereas normally with photographs it's easy to just sort of look at it more abstractly without really thinking about it. Could be a neat party game even as-is, but I also agree with a sibling poster that it'd be easy to expand a touch to favor that (allow having n different guesses each with different colors, so everyone can take a shot for each image for some light competition maybe?).


* * *

So fun! Have some friends courious about culture and history that will love this.

I think the UX can improve a bit:

- Would like that after a submit show both the correct date and the player guess, now only shows the correct date on screen (and the guess in the slider but not with numbers, just a visual gap)

- The slider is a bit hard to interact on phones.


Also, it should show public info about public photos. If you photo search, you can easily find - and see some interesting information that the app could include. Example: https://www.prints-online.com/cub-scouts-taking-operation-sh...

I got a 1976 and a 1992 correct on my only attempt. What are the odds of that? You can narrow a picture down to roughly a 20 yr span. Is that 1 in 400 for just those two? Worst case would be 100 x 100?

At least one of the photos is mislabeled.

This one[0] shows time square with an ad for a UFC fight that happens in 2009, but it's labelled as 2007.

Wow, that's quite the lead up.

So simple, yet a lot of fun!

2,889 on my first round, 4,4xx on my second. It's fun zooming in and looking for cars, logos, and clothing style for hints. It's also neat to see, say, a road with cars from Model T style through to swoopy 1930s sedans. Contrast that with most historical movies where, if it's set in 1955, every car is from 1950 - 1957.


I improved with each round, so is clearly educational.

Is Top Score highest everyone has gotten because I just got 3063 which shows top.

That's yours. I got 4500~. If you score 800ish every round you get around 4000 already.

4409. Amazing how can you tell the approximate year by how the women are dressed, an exercise I hadn't done conscientiously before. Thanks!

A good game for kids to show them how to recognize different eras. Many clues in each pic, including the colors that are representative of the film/tech used.

As my last image in round 5 I got a photo of WWF where Mankind was on top of the hell in a cell. I guessed 1998 because of the meme and got it correct! It was the only image I hit dead on.

Same for me with Musk on stage with the Cybertruck (2019).

It would be more interesting if these popular photos were removed, and guessing would be based only on knowledge about clothing and hair styles, film type, car design, etc.

Great game!


4625! One was obvious (Biden inauguration), and another I got lucky with a dead on guess.

I played this with my 8 y.o. son. I called it a social studies activity, was that accurate?

Absolutely. It would help if the results included some context for the photo, but that seems like a great way to spend educational & fun time with your son.

Just beware there seems to be little content filtering, one of the images I got was pictures of war casualties tossed on the side of the road from 2015.

Extremely enjoyable, thank you!

This is very fun, but I'm wondering why you haven't included source or some context for the photos? Also, you've disabled right click so reverse image searching them is painful.

>disabled right click

Try Shift + Right click to bypass this.


Unfortunately, that's not working for me on mac or linux :(

Maybe it is a Firefox only feature? Works fine for me on Linux.

Screenshot

My issue is there being no credits or sources for the image. Screenshot and reverse image search is certainly a solution on my end to get to that info, but it should be present on the website, probably at the round summary.

Was fun. Got 2 perfect out of the 5 on my first try :) Score 3098 total

Score: 2358. In general I was within 5 years except for the first one where I was off by 12.

I recently been going through all of my family photos. A lot of them are scanned and undated. I’ve been looking for some kind of machine learning library that will allow me to automatically date them. Approximates are fine, but an algorithm would do better than I would. Even just grouping photos of similar film stock and scene would be useful as they’re all completely jumbled. Does anyone know if there’s anything like that?

That’s an awesome app, I love that!

These photos are gorgeous. Love the photos that were selected. Are you willing to share the source for the photos?

Like others, I wish there was some info about the photos like context, location or source (Wikipedia?).

Anyway, here's the complete dataset (funny way to store it):

https://www.chronophoto.app/badSneakers.txt

Also, I couldn't resist and cheated a bit to see if you'ld get something special for 5000, but nothing :(

https://imgur.com/a/aEUMZlJ


Ooh I got the high score it seems! On the first try! First three I did exceptionally well:

I said 1942 Photo was taken in 1943 924 points

I said 1925 Photo was taken in 1927 849 points

I said 1985 Photo was taken in 1986 924 points

I said 1957 Photo was taken in 1942 117 points

I said 1931 Photo was taken in 1923 453 points

NYEH NYEH!

Final Total: 3267 High Score: 3267


Trying to use this on mobile sure is frustrating. I pinch zoom to look at the photo and somehow I end up changing photos when I zoom back out to click the buttons.

My scores are getting progressively better and I’ve reached 4481 by the 5th game!

I guessed better with photos that had telling elements such as hair styles, clothing, cars, beards - and preferably more than one instance of them. Bigger samples got to better results.

Fun game overall. OP, thanks for sharing the link.


I came back to play again after 10 hours and noticed some of the 1950's photos are fake colored and fooled me. I think those photos make this game less authentic.

Would be interesting if all pictures were black and white, irrespective of when they were taken.

Or the other way round, have some AI colorize the older pictures.


score 3203!

I feel I'd be doing better at this game if I was a car person. The only time I've got the year spot on was with a photo of the toppling of a statue of Saddam Hussein. The worst I did was guess 1960 on a black and white photo taken almost directly above of some cars on a road, it was actually 1980.

Fun but tricky


I was a cat nut in middle school. The four photos with cars? All guessed within 5 years. The one without a car? Off by 30 years.

Would be interesting to train an AI on another dataset and then see how it does on this

First two games I tried I did pretty well on (~3000 score?), then had some shockers (at least 2 or 3 I'd need some convincing on, photos dated in the 30s that were in full high resolution colour?), then got lucky with 3 photos clearly in the early 1900s, one with a cinema listing a film I knew the release year for and one with a somewhat iconic pre-war coca cola ad that I managed to pick the exact year for, scored just over 4400 (I guess 5k's the max?). Willing to bet a suitably trained AI would whoop any human's ass though, even ensuring none of the photos were explicitly part of the training data.

Why would photos dated in the 30s that were in full high resolution colour be surprising?

Resolution has never been a problem for early color photos, the actual coloring was, and the expense/difficulty of the process.

This - https://en.wikipedia.org/wiki/Sergey_Prokudin-Gorsky#/media/... and this https://en.wikipedia.org/wiki/Sergey_Prokudin-Gorsky#/media/... - come from 1910s.

And in 1935-1936 effectively modern color film was mass-released, so starting from late 30s nothing should be surprising.


Perhaps, but this particular one (looked like some dignitary inspecting an army, assuming an Asian country but couldn't say which) was especially crisp with high colour saturation that didn't match that of other photos from that period, indeed I assumed it was from the 70s or 80s.

https://jsfiddle.net/9dvx1sua/show is another photo I would never have guessed the year of from the quality of the image. Even if the outfits/equipment are obviously from a particular period, I'd think it was a reenactment or a scene from a movie...

Love it! Nice job.

It would be nice to have a link with more information about the single photos, at least the exact time and place where it was shot, i can then look for the related events myself.


3820 so far I like this

My best over probably 50 games was 4261. It's really fun to play with other people too and make guesses together.

  for (i=1;i<6;i++) console.log(i+' '+Math.round(sessionStorage.getItem("realDate"+i)/29.234));

It would be interesting to see results around what styles and ages of photos people are worse at guess age for on average.
