It's the Pythagorean theorem expressed as a date.

2025-09-16 => 452 = 32 + 42 + fudge And that kids is how I failed maths

But the accurate expression of that date 20250927 does not.

This date format is vulnerable to the Y2K problem. This date format is not ISO 8601 compliant.

by TwoSlow4198 1 week ago

The Y2K problem had nothing to do with the date format and entirely to do with data storage limits. Well, ok, it was a format issue, but the only problem was that the year part of the date was written as two numbers, which was often done to save space. Technically speaking, the order didn't matter at all. The year could have been in the second spot, and there wouldn't have been an issue. ISO prevents the Y2K problem, but it is in no way needed to do so.

One could say: 2025/09/16: 52 = 32 + 42

by Graciekertzmann 1 week ago

TIL that 52 = 452

If we just use the last 2 digits of the year it'd be every 100, not 1000

That's still three squared numbers: 42 32 452

It makes sense for the same reason. And that does not happen daily. Seems like you're grasping for excuses to feel superior.

How and more importantly, why would I feel superior about this. This has nothing to do with me.

That just means you acted like a jerk but didn't even get the benefit of feeling superior.

If you use European dates there are even fewer for ascending squares In the US you can have 9/16/25 as valid but in Europe 9/16/25 is invalid because we don't have 16 months

I like that in one of Mr Bungle's older songs, Mike says 1, 4, 9 instead of 1, 2, 3

If you consider that 3x3 + 4x4 = 5x5 then the answer is: This will only happen once every century. Fermat's famous theorem shows that there are no other natural numbers where the sum of powers of two numbers is equal to the power of another number.

I had noticed the month and date were unique while writing the date at work today, just didn't think about the year

by Ibashirian 1 week ago

It happens just like any other number, it's only significant if you want it to be

by Lebsackkarley 1 week ago

how often does that happen? I don't know, what do you mean by "that"?
