Hanukkah of Data: Practice your data skills with 8 free data puzzles (bluebird.sh)

I'm working with some data that has a large number of date formats within a single document - day seconds, week seconds, ISO8601, ticks, some with hardcoded offsets and others with different datums ... it would be quite funny I think to throw in a new column in the Hebrew calendar, just to join the party, so to speak.


The Hebrew calendar is a marvel of historical engineering and complexity. Both solar and lunar with exceptions to accommodate Shabbat and other holidays, and be consistent with the Torah.

I haven't seen glazing this hard at a cinnabun.


Thanks for the link! Better than the articles I came across before. It has a kind of GEB vibe to it which is nice.


Discussed on HN last year. The top comment has some other links you might be interested in:

That is a very good link. The top comment has direct implications for any software / report generation dealing with tidal (-> lunar) cycles. Perhaps using something non-ISO to store time on the inside could have its benefits.


dwimmer's animated text art elevates everything about Hanukkah of Data! I wrote about how it works, here: https://evalapply.org/posts/animate-text-art-javascript/


You did a great job on the text animation code, Adi! I've found myself falling into a trance watching the flickering candles.


Aw shucks... thank you :)

And I find myself waiting to catch the various creatures twitch.


I know it's a week old, but I just finished and had a lot of fun! Thank you! I'm going to attempt the speed run after my toddler goes to sleep.


The ASCII candle is really charming, especially when lit. Looking forward to exploring this further. Great work!


Thanks for putting this together, it's very creative.

Do you mind if I post videos of solving this to my youtube channel (that has absolutely no viewers)


For sure! Just be sure to include a spoiler warning :)


Hey, Whats your Youtube channel name? I am interested in watching the videos of your Solutions for these Data Puzzles.


This was pretty fun! Sometimes the stories were a bit harder to parse than others, but honestly, that's pretty reflective of what it's like being a technical person communicating with non-technical people.

Hope to see this again next year!


I love the story! Excited for the next challenge!


Fun "crossover" observation (ROT13; spoiler for first night)

Congrats Saul! Hope it’s ok to solve this during Christmas, because of vacation ;-)


Thanks! It'll stay up past the end of Hanukkah.


Solved it all last year, looking forward to finishing this year’a puzzles!


Well, the puzzles are the same, only the clues and dataset are different. But you might want to do them again anyway, to polish up your scripts--on the last day of Hannukah, we'll be posting a more challenging dataset for you to try to speedrun.

And keep on the lookout for more data puzzles from us in the near future!


Pretty cool. Got the first two. Now I have to wait for the next one...


The phone number input requires dashes, which are entirely optional in general for communicating telephone numbers (dashes and parens only serve as decoration for readability these days).


Thanks for this, will give it a try :)


why can i only do the first 2 puzzles? it says i have to wait 17hrs. is it like a christmas countdown?


chanukah is 8 days. presumably one puzzle will be released each day.


Yes, exactly! A new puzzle will be released at 4pm UTC each day.


oh cool, can't wait for it.


Yay, it’s back!


im keen but not sure how to get started


Click on the candles to see the puzzle! Start with the 0th candle in the centre. =)
