There's also an alternative approach to put a leading 1 called Holocene Calendar: https://en.wikipedia.org/wiki/Holocene_calendar

I'm really surprised that it's 265 and not 256... I mean, there's got to be a good reason not to make it a round number, right? I'm mind blown anyways...

Was shooting for 256 but went over to implement touch events ;)

Well I guess that's the downfall of the touch screen era

The downfall is that you an add a complete secondary interface in 9 lines of code?

It's f(x) = (x0 + xn) * n/2 Where x0 - is the first element (here: 1) xn - last element (here: 3000) n - number of elements (here 3000)

That makes it: $4,501,500

I like that 'Rules of Usability'[1] that the article links to. It could be used as a great checklist for your apps.
