Best way to write the date. Year then month then day using numbers. Allows for easy sorting in computer for people and also no gets confused like they do in other systems.
It's an international standard handled by the ISO group
it also just make sense, we already put the more significant number on the left side when writing numbers anyways. MM/dd/YYYY is more like writing one hundred and twenty three as 231
I've grown accustomed to dates in this format, because of software engineering. Yesterday I had to write out MM/DD/YY on some paperwork, and it broke my brain for a good 30s trying to remember the format.
