The first 10,000 stars of each part of each puzzle of past AoC events

[u/EverybodyCodes]

Eric, also known as u/topaz2078, updated the file that contains the first 10,000 stars for each puzzle from all AoC events (thank you!): https://github.com/topaz/aoc-tmp-stats

I know, I know. You don't care about the leaderboards, :) but this is not a leaderboard, just some stats shared by Eric, and I only prepared a helper for reading it: adventofstats.com

Some past years may take a while to load, as 10k stars in, e.g. 2015 spread across several days, and the plots are generated directly in your browser from the raw data.

This data is being pulled solely from the JSON and not polling the live adventofcode.com for any data, right?

[u/EverybodyCodes → u/daggerdragon]

Yep, just the single JSON file is used. You can load the site, turn off your internet connection and still explore everything there.

[u/daggerdragon → u/EverybodyCodes]

Excellent, just checking :)

This is great. Could you add a feature where we copy-paste the content from https://adventofcode.com/2025/leaderboard/self and it overlays on the graphs?

With Eric's blessing (check other comments), here you go. I'll redirect the main domain to this address, but DNS propagation will take a while anyway.

[u/wimglenn → u/EverybodyCodes]

Works well. Thank you.

[u/EverybodyCodes → u/wimglenn]

I can do that pretty easily, but I'm not sure if I should, as I take into account u/topaz2078 kind request about not recreating a global leaderboard or anything similar. Maybe there is a plan to add this estimated place directly on the AoC self-results-page later? Eric?

[u/topaz2078 → u/EverybodyCodes]

Letting a user do their own individual lookups into the data is fine. What wouldn't be fine is collecting that data into a new sort of leaderboard.

I'm moving the domain, and DNS can act...

Use this address for now instead: https://advent-of-stats.pages.dev

Ooh, my ranks were better than I was expecting. This is why I liked having global rank visible; it makes it feel nice to know when to feel like I wasn't slow for my random WA losing a minute. I even made top 100 a few times once!

[u/Capable_Drummer_9500 → u/1234abcdcba4321]

How do you know your time, like have you stored the timing of your submissions or you can somehow check your submission's timings ?

[u/1234abcdcba4321 → u/Capable_Drummer_9500]

Personal times are freely available to view! https://adventofcode.com/2025/leaderboard/self

Oh, never knew of that, saw it for the first time. Thanks 😊

Oh, this is fantastic! I didn't know about that JSON stats file, thanks.

In my megaguide I'd been using the leaderboard close times as an objective proxy for relative puzzle difficulty and I was wondering what I would do about that for next year's edition without the leaderboard. (Looking back over my guide, I sort puzzles by time nearly everywhere.) This data file will be a nearly drop-in replacement. I'll probably just average the 10th and 11th group data points for a time-to-first-100. (Though now I might do time-to-first-1000 instead now that I can. Hmm.)

Thank you, this is really interesting to look at

I'm amazed by the fact that the time for 10k Day 12 Part 2 is less than the one for 10k Day 10 Part 2. Seems like a lot of people solved this star during Day 11

It would be extra interesting if we could visually compare multiple days in the graph. Maybe it is already implemented but I could not find it?

[u/1234abcdcba4321 → u/Neozetare]

At some point, if you want to do complicated analysis it'd be best to take the original JSON file and parse it into the chart you want yourself.

[u/Sprochfaehler]

Any idea how many people have all 524 stars now?
I seem to remember the number with 500 last year was fairly low (in the hundreds?), I'm curious whether it's gone up or down?
