Thoughts

Screenshot from the Dashboard.app showing 20,200,202 on the Calculator, a Calendar with Sunday 2nd February, and clocks.

We’ve got another palindromic date, if one were to write it without dashes. It even works across multiple formats:

  • The correct ISO 8601 convention as YYYY-MM-DD
  • The logically ordered but still incorrect DD-MM-YYYY
  • The illogically ordered and entirely incorrect MM-DD-YYYY

People who don’t use the ISO format are as bad as those who don’t use leading zeros on their dates and times. You know who you are.

I also discovered the Dashboard.app still exists, which I used to highlight the fact I took a screenshot at 20:02, which is also a palindrome. That’s also the correct way to write digital time, none of this ambiguous and verbose AM/PM nonsense!

I’ve told the story a few times, but I remember an Australian primary school teacher showing us a mnemonic for remembering AM and PM: AM is for After Midnight and PM is Past Midday. I scratched my head the whole walk home, wondering why it wasn’t After Midday and Past Midnight in that same system. And isn’t the evening technically still after midnight on that day?

AM/PM need to be relegated to the litter basket of history, along with the various incompatible Imperial systems, non-ISO dates, and coriander.
