Beautiful visualisation - I just wish I could hover over the grid and see which PIN my cursor is pointing at.

By counting grid points it looks like codes in the form 0[1-9][32-99] are the least common with a few exceptions (like 0990 or 0987).

I suspect this is leading zero bias: a leading zero is not meaningful mathematically and we tend to drop it. The exceptions are dates. The day first block doesn't extend vertically into an unused area but the month first one drops off a cliff around 32 because no month has 32 days.

It's nice but also flawed because you can't easily see if the first two digits are the same. Or the last two digits.

Kind of like GitHub's contribution graph? Which is an awesome little piece of design.
