MM/DD/YYYY

The shittiest date format in the world, only used by countries that lost their twin towers.

As an American, MDY sucks. So fucking confusing

Person 1: Today is 10/23/2024
Me: WHAT DATE IS THAT? IS THAT MM/DD/YYYY FORMAT? KILL YOURSELF YOU FUCKING CUNT
Person: but you're American...
Me: I DONT CARE IF IM AMERICAN, THE MONTH DAY YEAR FORMAT IS TRASH

Today is actually 23/10/2024
