NOOOO, which is month, which is day?!
ISO 8601 stipulates that units are in increasing specificity.
27 September 2018
Agreed actually. For filenames, ISO 8601 can't be beat because they sort correctly.
For all public facing communication, I try and try and try to get everyone in marketing to use the 27 September 2018 format and I try and try to explain that 20% of our customers do thing 03/04/18 is April 3 and 75% think it's March 4.... and 5% are like me and have no clue what day they mean.
I actually work with people who write date ranges this way: 4/7-9/10. What does that mean? It means April 7-9, 2010. It's less confusing now that we are past 2012. But still, 4/4-17/18 is almost unreadable.
But people persist in writing dates that way.
Gram-Kilo-Ton
I used to think this made sense. Rational. Organized. All that. Then Arlo Guthrie explained how bad the metric system is for poetry and song and I saw the fatal flaw.
Famous folk song rendered into metric:
"Centimeter by centimeter/gonna make this garden grow"
Famous poem rendered into metric:
"And kilometers to go before I sleep."
Famous play rendered into metric:
"The kilogram of flesh which I demand of him Is deerely bought, 'tis mine, and I will have it."
Sorry, but no. Just no. They should have picked better names ;-)
