The difficult part, which is glanced over, is calculating the number of leap years for the year "slide" in Part 5.
A bit more guidance there would go a long way.

Awesome site and guide, I just don't understand why all dates have the month in front of the date.
Isn't this very confusing to anyone outside US?
I get why it defaulted to this format, but in this day and age - it's trivial to automatically adjust it to the user's localization / preferences.

There are only two dates that aren't symmetrical - 3/14 and 2/28 - and they are easier to remember in the mm/yy format.

Yes that tripped me up a few times.
I’d also suggest that when the user guesses wrong and you show the “correct” working, also continue to show the date so they can work it through correctly. The date changes right away so you can’t rework it and understand your mistake.

Cool site! When I do this trick I prefer using Bob Goddard's 'first Sunday' method [0]. It minimises the number of operations you need to do and makes it so you only need to keep track of one running total.
Pretty sure he was not when I posted my comment. It currently says "more on him at the end" and that bit seems not to have been written yet. Also there are two mathematicians called "John Conway" so it's good form to say "John H Conway".

Author here, good call! I credit Conway in the center of the article, the content for "more on him at the end" was hidden after reader finish the challenge in part 6. I guess it worth to show it by default, updated already.
I'd also need to thanks for Dr. Arthur Benjamin. I saw his "That math show" with my 9 years old where he introduced this Doomsday rule, I thought it was really cool and try to create some interactive tutorial for it. Would love to see if this can help other kids or adults https://www.thatmathshow.com/

>The trick = nearest squad date → leftover → walk from the Doomsday.
When i do the 31/OCT, the solution show 10/10 as nearest squadday, i though 11/7 is the nearest ?

I can’t decide whether I find the AI writing or AI design more offensive.
Laughable that the footer has the stereotypical “made with <3” tagline (because of course AI has to use an emoji instead of words), for a site that almost certainly took less time to prompt than it takes to read it.
