@pabs @stragu It's literally just "the way you say it when you talk."

"When is Halloween?" "October thirty-first, I think."

🤷‍♀️

@Magess @pabs @stragu that's not universal. In British English we say "the 31st of October". Cause and effect are very strange here.
@iMartyn @Magess @pabs @stragu Brits used to say it the way Americans do but started changing in the late 19th century to align more closely with the mainland where in romance languages it was spoken with the day first. It's only the "standard" because Europe made it so. The actual ISO standard is YYYY-MM-DD. Apps should instead just adapt to the locale.
